Deployment Guide 45Chapter 4 The HiveAP 340 PlatformThe Aerohive HiveAP 340 is a high-performance and highly reliable 802.11n wireless access point. The HiveAP 340 provides dual concurrent 802.11b/g/n and 802.11a/n radios for 3x3 MIMO (Multiple In, Multiple Out) and dual 10/100/1000 Ethernet ports for link aggregation or link redundancy. Its power management system uses a concept called smart PoE (Power over Ethernet) to adjust its power consumption automatically in response the available power in different environments. Smart PoE supports the IEEE 802.3af standard and the 802.3at pre-standard.This chapter covers the following topics relating to the HiveAP:•"HiveAP 340 Product Overview" on page 46•"Ethernet and Console Ports" on page 48•"Status LEDs" on page 52•"Antennas" on page 52•"Mounting the HiveAP 340" on page 56•"Ceiling Mount" on page 56•"Surface Mount" on page 58•"Device, Power, and Environmental Specifications" on page 59

Deployment Guide 47 HIVEAP 340 PRODUCT OVERVIEW10/100/1000 Mbps PoE Ports The two 10/100/1000-Mbps Ethernet ports—ETH0 and ETH1—support IEEE 802.3af and 802.3at PoE (Power over Ethernet) and receive RJ-45 connectors. The HiveAP can receive power through one or both Ethernet connections from power sourcing equipment (PSE) that is compatible with the 802.3af standard and forthcoming 802.at standard. (If you connect the HiveAP to a power source through the power connector and PoE ports simultaneously, the device draws power through the power connector and automatically disables PoE.)You can configure ETH0 and ETH1 as two individual Ethernet interfaces, combine them into an aggregate interface to increase throughput, or combine them into a redundant interface to increase reliability. You can connect the HiveAP 340 to a wired network or to a wired device (such as a security camera) through these ports using bridging. They are compatible with 10/100/1000Base-T/TX and automatically negotiate half- and full-duplex connections with the connecting device. They are autosensing and adjust to straight-through and cross-over Ethernet cables automatically. For details, see "Ethernet and Console Ports" on page 48.Power Connector The 48-volt DC power connector (0.625 amps) is one of two methods through which you can power the HiveAP 340. To connect it to a 100 – 240-volt AC power source, use the AC/DC power adaptor that is available as an extra option. Because the HiveAP does not have an on/off switch, connecting it to a power source automatically powers on the device.Console Port You can access the CLI by making a serial connection to the RJ-45 console port. The management station from which you make a serial connection to the HiveAP must have a VT100 emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems). The following are the serial connection settings: bits per second: 9600, data bits: 8, parity: none, stop bits: 1, flow control: none. For details, see "Ethernet and Console Ports" on page 48.Reset Button The reset button allows you to reboot the device or reset the HiveAP to its factory default settings. Insert a paper clip, or something similar, into the Reset pinhole and press the reset button. To reboot the device, hold the button down between 1 and 5 seconds. To return the configuration to the factory default settings, hold it down for at least 5 seconds. After releasing the button, the Power LED goes dark as the system reboots. Then it pulses green while the firmware loads and the system performs a self-test. After the software finishes loading, the Power LED glows steady green.To disable the reset button from resetting the configuration, enter this command: no reset-button reset-config-enable Pressing the button between 1 and 5 seconds will still reboot the HiveAP, but pressing it for more than 5 seconds will not reset its configuration.Note: The rear surface of the HiveAP 340 is used for heat dissipation to reduce the internal temperature. Consequently, it can become hot, so use caution when handling it.Component Description
Chapter 4 The HiveAP 340 Platform48 AerohiveEthernet and Console PortsThere are three ports on the HiveAP 340: two RJ-45 10/100/1000Base-T/TX Ethernet ports and an RJ-45 console port.The pin assignments in the PoE (Power over Ethernet) Ethernet ports follow the TIA/EIA-568-B standard (see Figure 2). The ports accept standard types of Ethernet cable—cat3, cat5, cat5e, or cat6—and can receive power over this cable from power sourcing equipment (PSE) that is 802.3af-compatible. If you use cat5, cat5e, or cat6 cables, the HiveAP 340 can also support 802.3at-compliant PSE. Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that inject power into the Ethernet line en route to the HiveAP. Because the PoE ports have autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or cross-over.Figure 2 PoE Wire Usage and Pin AssignmentsETH0Pin T568A Wire Color1 White/Green2 Green3 White/Orange4Blue5 White/Blue6 Orange7 White/Brown8Brown(View of the ETH0 PoE Port on the HiveAP 340)8 1Pin NumbersPin T568B Wire Color1 White/Orange2 Orange3 White/Green4Blue5 White/Blue6 Green7 White/Brown8BrownT568A-Terminated Ethernet Cable with an RJ-45 Connector802.3af Alternative A(Data and Power on the Same Wires)802.3af Alternative B(Data and Power on Separate Wires)802.3at Wiring OptionsPin Data Signal MDI MDI-X MDI or MDI-X 1 2 3 41 Transmit + DC+ DC– – – – DC1+ DC1– DC1+ DC1–2 Transmit - DC+ DC– – – – DC1+ DC1– DC1+ DC1–3 Receive + DC– DC+ – – – DC1– DC1+ DC1– DC1+4 (unused) – – – – – – DC+ DC2+ DC2+ DC2– DC2–5 (unused) – – – – – – DC+ DC2+ DC2+ DC2– DC2–6 Receive - DC– DC+ – – – DC1– DC1+ DC1– DC1+7 (unused) – – – – – – DC– DC2– DC2– DC2+ DC2+8 (unused) – – – – – – DC– DC2– DC2– DC2+ DC2+MDI = Medium dependent interface for straight-through connectionsMDI-X = Medium dependent interface for cross-over (X) connectionsThe PoE ports are auto-sensing and can automatically adjust to transmit and receive data over straight-through or cross-over Etherneconnections. Likewise, they can automatically adjust to 802.3af Alternative A and B power delivery methods. Furthermore, when the Alternative A method is used, the ports automatically allow for polarity reversals depending on their role as either MDI or MDI-X. In 802.3at, the 1/2 and 3/6 wire pairs connect to DC source 1 and 4/5 and 7/8 pairs to DC source 2 in PSE. Although the exact polarity depends on the PSE design, the HiveAP 340 Ethernet ports can support all possible options.T568B -terminated Ethernet Cable with an RJ-45 ConnectorT568A and T568B are two standard wiring termination schemes. Note that the only difference between them is that the white/green + solid green pair of wires and the white/orange + solid orange pair are reversed.For straight-through Ethernet cables—using either the T568A or T568B standard—the eight wires terminate at the same pins on each end.For cross-over Ethernet cables, the wires terminate at one end according to the T568A standard and at the other according to T568B.
Deployment Guide 49 HIVEAP 340 PRODUCT OVERVIEWSmart PoEThe HiveAP 340 applies the Aerohive concept of smart PoE to adjust power consumption as necessitated by varying levels of available power. If the HiveAP needs more power than is available, it first disables the ETH1 interface. If it still needs more power, it switches from 3x3 MIMO (Multiple In, Multiple Out) to 2x3 (see "MIMO" on page 53). In rare cases when further power conservation is necessary, the HiveAP then reduces the speed on ETH0 from 10/100/1000 Mbps to 10/100 Mbps. Finally, in the event that there is a problem with the PoE switch or Ethernet cable, the HiveAP disables its wireless interfaces and returns its ETH0 and ETH1 interfaces to 10/100/1000 Mbps speeds. Through the application of smart PoE, the HiveAP 340 can make power usage adjustments so that it can continue functioning even when the available power level drops.Aggregate and Redundant InterfacesBy default ETH0 and ETH1 act as two individual Ethernet interfaces. When both interfaces are connected to the network and are in backhaul mode, the HiveAP transmits broadcast traffic only through ETH0. The HiveAP transmits broadcast traffic through ETH1 only when ETH0 does not have network connectivity. When both Ethernet interfaces are connected to the network and are in access mode, then the HiveAP transmits broadcast traffic through all the access interfaces: ETH0, ETH1, and all wireless subinterfaces in access mode.In addition to using ETH0 and ETH1 as individual interfaces, you can combine them into an aggregate interface (agg0) to increase throughput, or combine them into a redundant interface (red0) to increase reliability. The logical red0 and agg0 interfaces support all the settings that you can configure for Ethernet interfaces except those pertaining to physical link characteristics such as link speed. See the sections below for configuration information.Aggregate InterfaceYou can increase throughput onto the wired network by combining ETH0 and ETH1 into a single logically aggregated interface called "agg0". The aggregate interface effectively doubles the bandwidth that each physical has when used individually. In this configuration, both Ethernet ports actively forward traffic, the HiveAP applying an internal scheduling mechanism based on the source MAC address of each packet to send traffic through the aggregate member interfaces. To configure an aggregate interface, enter the following commands:interface eth0 bind agg0interface eth1 bind agg0In addition to configuring the HiveAP, you must also configure the connecting switch to support EtherChannel. For example, the following commands bind two physical Ethernet ports—0/1 and 0/2—to the logical interface port-channel group 1 on a Cisco Catalyst 2900 switch running Cisco IOS 12.2:Switch#conf tSwitch(config)#interface port-channel 1Switch(config-if)#switchport mode accessSwitch(config-if)#spanning-tree portfastSwitch(config-if)#exitSwitch(config)#interface fastEthernet 0/1Switch(config-if)#switchport mode accessSwitch(config-if)#channel-group 1 mode onSwitch(config-if)#spanning-tree portfastSwitch(config-if)#exit

In this mode, only one Ethernet interface is actively forwarding traffic at any one time. If eth0 is active and eth1 is passive and eth0 loses its connection, the HiveAP switches over to eth1. To configure a redundant interface, enter the following commands:interface eth0 bind red0 primaryinterface eth1 bind red0The interface that you specify as primary is the one that the HiveAP uses when both interfaces have network connectivity. Because the HiveAP uses eth0 as the primary interface, it is unnecessary to specify "primary" in the first command above. However, it is included to make the role of eth0 as the primary interface obvious. Interface Selection for the Default RouteIn cases where there are multiple active interfaces in backhaul mode, the HiveAP uses the following logic to choose which interface to use in its default route: • If there is an Ethernet interface and a wireless interface in backhaul mode, the HiveAP uses the Ethernet interface in its default route.• If there are multiple Ethernet interfaces in backhaul mode, the HiveAP chooses which one to use in its default route in the following order:• It uses red0 or agg0 if one of them has at least one member interface bound to it and its link state is UP.• It uses ETH0 if neither red0 nor agg0 has any member interfaces and the link state for ETH0 is UP.• It uses ETH1 if neither red0 nor agg0 has any member interfaces, the link state for ETH0 is DOWN, and the link state for ETH1 is UP.Note: No extra configuration is necessary on the connecting switch or switches to support a redundant interface.

Insert the RJ-45 connector into the HiveAP 340 console port, and attach the DB-9 connector to the serial (or COM) port on your management system. The management system must have a VT100 terminal emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems).

Chapter 4 The HiveAP 340 Platform52 AerohiveStatus LEDsThe five status LEDs on the top of the HiveAP 340 indicate various states of activity through their color (dark, green, amber, and red) and illumination patterns (steady glow or pulsing). The meanings of the various color + illumination patterns for each LED are explained below.Power•Dark: No power• Steady green: Powered on and the firmware is running normally• Pulsing green: Firmware is booting up• Steady amber: Alarm indicating a firmware issue has occurred• Pulsing amber: Firmware is being updated• Steady red: Alarm indicating a hardware issue has occurredETH0 and ETH1• Dark: Ethernet link is down or disabled• Steady green: 1000 Mbps Ethernet link is up but inactive• Pulsing green: 1000 Mbps Ethernet link is up and active• Steady amber: 10/100 Mbps Ethernet link is up but inactive• Pulsing amber: 10/100 Mbps Ethernet link is up and activeWIFI0 and WIFI1• Dark: Wireless interface is disabled• Steady green: Wireless interface is in access mode but inactive• Pulsing green: Wireless interface is in access mode and active• Steady amber: Wireless interface is in backhaul mode but inactive• Pulsing amber: Wireless interface is in backhaul mode and active• Alternating green and amber: Wireless interface is in backhaul mode and is searching for other hive membersAntennasThe HiveAP 340 can accept up to six detachable dipole antennas. The three shorter antennas are designed for the 5 GHz band and have a 2-dBi gain. The three longer antennas are designed for the 2.4 GHz band and have a 4.9-dBi gain. These antennas are omnidirectional, providing fairly equal coverage in all directions in a toroidal (donut-shaped) pattern around each antenna (see Figure 4 on page 28). For greater coverage on a horizontal plane, it is best to orient the antennas vertically. So that you can easily do that whether the HiveAP chassis is mounted horizontally or vertically, the antennas hinge and swivel (see Figure 5 on page 53.)Although hive members automatically adjust their signal strength according to their environments, you can resize the area of coverage by increasing or decreasing the signal strength manually by entering the interface { wifi0 | wifi1 } radio power <number> command, where <number> can be from 1 to 20 and represents a value in dBm.
Deployment Guide 53 HIVEAP 340 PRODUCT OVERVIEWFigure 5 HiveAP 340 AntennasMIMOMIMO (Multiple In, Multiple Out) is a major WLAN advancement introduced in the IEEE 802.11n standard in which multiple RF links are formed on the same channel between the transmitter and receiver simultaneously. To accomplish this, the transmitter separates a single data stream into multiple spatial streams, one for each RF chain (an antenna + various digital signal processing modules linked to the antenna). The transmit antennas at the end of each RF chain then transmit their spatial streams. The recipient’s receive antennas obtain streams from all the transmit antennas. In fact, due to multipath, they receive multiple streams from each transmit antenna. The receive antennas pass the spatial streams to the digital signal processors in their RF chains, which take the best data from all the spatial streams and reassemble them into a single data stream once again (see Figure 6).Figure 6 2x2 MIMO (2 Transmit Antennas x 2 Receive Antennas)5 GHz Antenna for IEEE 802.11a/nLength when fully extended: 5 15/16” (15 cm)2.4 GHz Antenna for IEEE 802.11b/g/nLength when fully extended: 7 7/8” (20 cm)The base of the antennas hinge up to 90 degrees so that you can orient the antennas independently of the orientation of the HiveAP chassis. The antennas also rotate in a full circle.When mounting the HiveAP 340 on a ceiling, orient its antennas downward.When mounting the HiveAP on a wall or post, fully extend its antennas upward and downward.When mounting the HiveAP above a ceiling or on a horizontal beam, orient its antennas upward.Generally, orient the antennas vertically for improved radio coverage, as shown here:Transmit AntennasDigital Signal ProcessorsRF Chains RF Signals (Multipath)Receive Antennas Digital Signal ProcessorsRF Chains802.11n wireless client with two antennas HiveAP 340 using two antennasObjectData Reassembled Data
Chapter 4 The HiveAP 340 Platform54 AerohiveIn previous 802.11 standards, access points and clients each employed a single set of components, or RF chain, for transmitting or receiving. Although two antennas are often used for diversity, only the one with the best signal-to-noise ratio is used at any given moment, and that antenna makes use of the single RF chain while the other antenna remains inactive. A significant improvement that MIMO introduces is to permit each antenna to have its own RF chain and for all antennas to function simultaneously. For the HiveAP 340, you can connect up to three antennas per radio and configure the radio to use two or three transmit chains and two or three receive chains.1 Using two or three transmit and receive chains simultaneously increases the amount of data that can flow across the WLAN and accelerates the processing of that data at each end of the wireless link.Another major aspect of MIMO is how it turns multipath signals from a curse to a boon. As a radio signal moves through space, some objects reflect it, others interfere with it, and still others absorb it. The receiver can end up receiving multiple copies of the original signal, all kind of muddled together. However, the digital signal processors in the multiple receive chains are able to combine their processing efforts to sort through all the received data and reconstruct the original message. Furthermore, because the transmitter makes use of multiple RF chains, there is an even richer supply of signals for the receive chains to use in their processing. To set the transmit and receive RF chains for a radio profile, enter the following commands:radio profile <name> transmit-chain { 2 | 3 }radio profile <name> receive-chain { 2 | 3 }There are two sets of antennas—three antennas per set—that operate concurrently in two different frequency ranges: 2.4 GHz (IEEE 802.11b/g/n) and 5 GHz (IEEE 802.11a/n). Using two different frequency ranges reduces the probability of interference that can occur when numerous channels operate within the same range. Conceptually, the relationship of antennas and radios is shown in Figure 7.Figure 7 Antennas and Radios\The wifi0 interface links to radio 1 (frequency range = 2.4 GHz for IEEE 802.11b/g), and the wifi1 interface links to radio 2 (frequency range = 5 GHz for IEEE 802.11a). These interface-to-radio relationships are permanent.When deciding how many antennas to use, consider the types of wireless clients—802.11n only, 802.11g/n, 802.11b/g/n, or 802.11a/n—the area needing coverage, and the RF environment.1. The convention for presenting the configuration of transmitting and receiving MIMO RF chains is TxR. For example, a HiveAP 340 radio functioning in access mode might be configured to use two RF chains for transmitting and three for receiving. In that case, its configuration can be presented as "2x3". In general, the number of receive antennas is equal to or greater than the number of transmit antennas.PWRETH1ETH0WIFI1WIFI0Radio 1RF 802.11b/g/n2.4 GHzRadio 2RF 802.11a/n5 GHz2.4 GHz (A)2.4 GHz (B)2.4 GHz (C)5 GHz (A)5 GHz (B)5 GHz (C)RP-SMA ConnectorsRP-SMA ConnectorsCut-away view of the HiveAP 340 to show the relationship of the antennas and the two internal radios
Deployment Guide 55 HIVEAP 340 PRODUCT OVERVIEWUsing MIMO with Legacy ClientsIn addition to supporting up to 300-Mbps throughput per radio for 802.11n clients, MIMO (Multiple In, Multiple Out) can improve the reliability and speed of legacy 802.11a/b/g client traffic. When an 802.11a/b/g access point does not receive acknowledgement that a frame it sent was received, it resends that frame, possibly at a somewhat lower transmission rate. If the access point must continue resending frames, it will continue lowering its transmission rate. As a result, clients that could get 54-Mbps throughput in an interference-free environment might have to drop to 48- or 36-Mbps speeds due to multipath interface. However, because MIMO technology makes better use of multipath, an access point using MIMO can continue transmitting at 54 Mbps, or at least at a better rate than it would in a pure 802.11a/b/g environment, thus improving the reliability and speed of 802.11a/b/g client traffic.Although 802.11a/b/g client traffic can benefit somewhat from an 802.11n access point using MIMO, supporting such legacy clients along with 802.11n clients can have a negative impact on 802.11n client traffic. Legacy clients take longer to send the same amount of data as 802.11n clients. Consequently, legacy clients consume more airtime than 802.11n clients do, causing greater congestion in the WLAN and reducing 802.11n performance. By default, the HiveAP 340 supports 802.11a/b/g clients. You can restrict access only to clients using the IEEE 802.11n standard. By only allowing traffic from clients using 802.11n, you can increase the overall bandwidth capacity of the access point so that there will not be an impact on 802.11n clients during times of network congestion. To do that, enter the following command:radio profile <string> 11n-clients-onlyYou can also deny access just to clients using the IEEE 802.11b standard, which has the slowest data rates of the three legacy standards, while continuing to support 802.11a and 802.11g clients. To do that, enter the following command:no radio profile <string> allow-11b-clientsBy blocking access to 802.11b clients, their slower data rates cannot clog the WLAN when the amount of wireless traffic increases.
Chapter 4 The HiveAP 340 Platform56 AerohiveMOUNTING THE HIVEAP 340Using the mounting plate and track clips, you can mount the HiveAP 340 to the tracks of a dropped ceiling grid. Using just the mounting plate, you can mount the HiveAP to any surface that can support its weight (3.3 lb., 1.5 kg).Ceiling MountTo mount the HiveAP 340 to a track in a dropped ceiling, you need the mounting plate, two track clips, and two Keps nuts that ship as an option with the HiveAP 340. You also need a wrench and—most likely—a ladder.Nudge the ceiling tiles slightly away from the track to clear some space. Attach the track clips to the ceiling track, and then fasten the mounting plate to the clips, as shown in Figure 8. When you have the mounting plate in the correct location, cut or drill a hole in the ceiling through which you can then pass the Ethernet and power cables.Figure 8 Attaching the Track Clips and Mounting Plate to the Ceiling TrackAttach the HiveAP 340 to the mounting plate and connect the cables, as shown in Figure 9 on page 57.Note: You can tie the cables to the tie points (small arched strips) on the mounting plate to prevent them from being pulled out of their connections accidentally.12Press the track clips against the ceiling track and swivel them until they grip the edges of the track.If necessary, slide one or both of the clips along the track to position them at the proper distance to fit through the holes in the mounting plate (2 1/4” or 7 cm).Insert the mounting plate over the bolts attached to the track clips, and use the Keps nuts to fasten the plate to the clips. Use a wrench to tighten the nuts firmly to the bolts and secure the plate to the track.3Through the oblong opening in the plate, cut or drill a hole in the ceiling tile (not shown). Then pass one or both Ethernet cables through the hole, and if you plan to supply power from an AC power source rather than through PoE, pass the power cable through as well.Cut hole in ceiling tile and feed cables through here.Mounting PlateCeiling TrackTrack Clip(worms’s eye view with ceiling tiles removed for clarity)2 1/4 “ (7 cm)

Chapter 5 The HiveManager Platform64 AerohiveThe pin assignments in the male DB-9 console port follow the EIA (Electronic Industries Alliance) RS-232 standard. To make a serial connection between your management system and the console port on the HiveManager, you can use a null modem serial cable, use another serial cable that complies with the RS-232 standard, or refer to the pin-to-signal mapping shown in Figure 3 to make your own serial cable. Connect one end of the cable to the console port on the HiveManager and the other end to the serial (or COM) port on your management system. The management system must have a VT100 terminal emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems).Figure 3 Console Port Pin AssignmentsThe serial connection settings are as follows:• Bits per second: 9600• Data bits: 8• Parity: none•Stop bits: 1• Flow control: noneStatus LEDsThe two status LEDs on the front of the HiveManager indicate various states of activity through their color (dark, green, amber) and illumination patterns (steady glow or blinking).

Deployment Guide 65 RACK MOUNTING THE HIVEMANAGERRACK MOUNTING THE HIVEMANAGERYou can mount the HiveManager in a standard 19" (48 cm) equipment rack with two rack screws—typically 3/4", 1/2", or 3/8" long with 10-32 threads. The HiveManager ships with mounting brackets already attached to its left and right sides near the front panel (see Figure 1 on page 62). In this position, you can front mount the HiveManager as shown in Figure 5. Depending on the layout of your equipment rack, you might need to mount the HiveManager in reverse. To do that, move the brackets to the left and right sides near the rear before mounting it.Figure 5 Mounting the HiveManager in an Equipment Rack1. Position the HiveManager so that the holes in the mounting brackets align with two mounting holes in the equipment rack rails.2. Insert a screw through a washer, the hole in one of the mounting brackets, and a hole in the rail.3. Tighten the screw until it is secure.4.

Be sure that air flow through the system fan vents is not obstructed.Dual AC Power Supplies There are two power supplies. Each three-prong AC power inlet is a C14 chassis plug through which you can connect the HiveManager to a 100 – 240-volt AC power source using the 10-amp/125-volt IEC power cords that ship with the product. By cabling each power supply to a different source, they provide redundancy in the event of a single power failure. Each power supply has a fan that maintains its temperature. It is important that nothing obstructs the air flow to these fans so that the power supplies do not overheat.Component Description
Chapter 6 The High Capacity HiveManager Platform70 AerohiveRACK MOUNTING THE HIGH CAPACITY HIVEMANAGERUse the rack mounting kit to mount the High Capacity HiveManager in a standard 19" (48 cm) equipment rack. The rack mounting kit contains the following items:• (2) slide sets (each consisting of an outer slide, inner slide, and chassis rail)• (2) rear mounting brackets•(4) bar nuts•(4) locator pins• (6) slot-head machine screws with 8-32 threads – for attaching the mounting brackets to the outer slides• (14) cross-head machine screws with 10-32 threads – for attaching the chassis rails to the HiveManager, and the front and the rear mounting brackets to equipment rack rails with tapped holes or to the enclosed bar nuts when the rack rails have round holes1. After checking that the mounting kit contains the above parts, separate the chassis rails from each slide set, as shown in Figure 2.Figure 2 Separating the Chassis Rail from the Nested Slides2. Position one of the chassis rails so that the slide stop is near the HiveManager mounting bracket near the front panel and the front and rear holes in the chassis rail align with the holes in the side of the HiveManager. Use three of the cross-head screws to secure the chassis rail to the HiveManager chassis as shown in Figure 3 on page 71.Note: Because of the weight of the device (34 lb./ 15.42 kg without rails) , two people are required to rack mount it safely.Outer SlideInner SlideChassis RailExtend the telescoping pieces of the slide set to the left and right.Outer SlideInner SlideChassis RailSwivel the catch to release the chassis rail, and then slide it compleletely away from the nested slides.Turn over.Catch

Use three slot-head screws to attach the rear mounting bracket to the outer slide. Insert the screws through the rounded slots in the outer slide into the threaded holes in the bracket and tighten them as shown in Figure 4.Figure 4 Attaching the Rear Bracket to the Outer Slide5. Use the remaining three slot-head screws to attach the other rear mounting bracket to the other outer slide.6. Fasten the rear mounting brackets—and the slides attached to them—to the rear equipment rack rails. Depending on the type of holes in the equipment rack, use one of the following methods:• For tapped (threaded) holes, use two screws to fasten the brackets directly to the rack rails. Use the cross-head screws (with 10-32 threads) if they fit the holes in the rack.• For round holes, use the cross-head screws to fasten the brackets through the holes in the rack rails to the bar nuts. You can use the locator pins to help keep the bar nuts aligned to the holes.

Chapter 6 The High Capacity HiveManager Platform74 AerohiveREPLACING HARD DISK DRIVESTo provide fault tolerance from disk errors and single disk failure, the high capacity HiveManager uses level 1 RAID (Redundant Array of Independent Drives) HDDs (hard disk drives). Each HDD holds identical data, the data that is written to one disk being mirrored to the other. The lower LEDs on the front of each HDD flash in unison to indicate that they are writing data to memory. The upper LEDs indicate that they have power. See Figure 8.Figure 8 Hard Disk Drive LEDsIf you notice that only one of the lower LEDs is flashing while the other is dark, then there is a HDD failure. Although the HiveManager can continue with just one operational HDD, you should replace the faulty HDD soon.1. Turn off the HiveManager.2. Unlock the HDD tray door for the disk that you want to replace.3. Pull the tab on the left side of the door, and open the door, swivelling it on the hinge along its right side.As you open the door, the HDD tray automatically extends.4. Remove the failed HDD and insert a replacement5. Close the door and lock it again.6. Connect a serial cable to the console port7. Connect one end of an RS-232 serial cable to the male DB-9 console port on the HiveManager and other end to the serial port (or COM port) on your management system.8. Start a serial connection as explained in "Changing Network Settings" on page 79.9. Turn on the HiveManager.10. While it is booting up, press and hold down the CTRL+A keys until the utility console appears.11. From the main menu, select Manage Arrays. (An array is the logical representation of a physical HDD unit.)12. From the list of arrays, select the one that you want to rebuild.13. Press CTRL+R to rebuild it.The rebuild process takes about 30 minutes. When done, the utility console notifies you with a message.14. Confirm that the process is complete.The HiveManager continues booting up with the new HDD replacement in operation.Note: HiveManager HDDs are not hot swappable. You must turn off the power before replacing a HDD.Note: The replacement disk drive must be new or, if it has been used, there must not be a root file system on it. Also, it must be the same size as or bigger than the other disk drive.Upper LED: Power Status (Illuminates when the HDD first receives power)Lower LED: HDD Activity (Illuminates when writing to memory)Hard Disk Drive TrayLockTab

Chapter 6 The High Capacity HiveManager Platform76 Aerohive
Deployment Guide 77Chapter 7 Using HiveManagerYou can conceptualize the Aerohive cooperative control architecture as consisting of three broad planes of communication. On the data plane, wireless clients gain network access by forming associations with HiveAPs. On the control plane, HiveAPs communicate with each other to coordinate functions such as best-path forwarding, fast roaming, and automatic RF (radio frequency) management. On the management plane, HiveManager provides centralized configuration, monitoring, and reporting of multiple HiveAPs. These three planes are shown in Figure 1.Figure 1 Three Communication Planes in the Aerohive Cooperative Control ArchitectureAs you can see in Figure 1, HiveManager operates solely on the management plane. Any loss of connectivity between HiveManager and the HiveAPs it manages only affects HiveAP manageability; such a loss has no impact on communications occurring on the control and data planes.The management plane is the logical division of administrative traffic relating to the configuration and monitoring of HiveAPs. From a management system, an admin can use the HiveManager to configure, maintain, and monitor multiple HiveAPs, essentially coordi-nating the control and data planes from a single, central location.Data PlaneControl PlaneManagement PlaneThe data plane is the logical division of wireless client traffic (user data) traversing a wireless-to-wired LAN. Traffic in the data plane follows optimal paths that various mechanisms in the control plane determine.The control plane is the logical division of traffic that hive members use to collaborate on how best to forward user data, coordinate radio frequencies, and provide layer-2 and layer-3 roaming capabilities with each other.To the wired network ...Management System
Chapter 7 Using HiveManager78 AerohiveThis chapter explains how to do the following basic tasks:• Use the console port to change the network settings for the MGT and LAN interfaces• Power on HiveManager and connect it to a network• Make an HTTPS connection from your management system to HiveManager and log in to the GUIIt then introduces the HiveManager GUI and includes a summary of the configuration workflow. Finally, the chapter concludes with procedures for updating HiveManager software and HiveAP firmware. The sections are as follows:•"Installing and Connecting to the HiveManager GUI" on page 79•"Introduction to the HiveManager GUI" on page 82•"Cloning Configurations" on page 83•"Multiselecting" on page 83•"Sorting Displayed Data" on page 84•"HiveManager Configuration Workflow" on page 85•"Updating Software on HiveManager" on page 86•"Updating HiveOS Firmware" on page 87•"Updating HiveAPs in a Mesh Environment" on page 88
Deployment Guide 79 INSTALLING AND CONNECTING TO THE HIVEMANAGER GUIINSTALLING AND CONNECTING TO THE HIVEMANAGER GUITo begin using the HiveManager GUI, you must first configure the MGT interface to be accessible on the network, cable HiveManager and your management system (that is, your computer) to the network, and then make an HTTP connection from your system to the MGT interface and download the GUI application.Besides HiveManager and your management system, you need two or three Ethernet cables and a serial cable (or "null modem"). The Ethernet cables can be standard cat3, cat5, cat5e, or cat6 cables with T568A or T568B terminations and RJ-45 connectors. The serial cable must comply with the RS-232 standard and terminate on the HiveManager end with a female DB-9 connector. (For more details, see "Ethernet and Console Ports" on page 63.)The GUI requirements for the management system are as follows:• Minimum screen resolution of 1024 x 768 pixels• Standard browser—Aerohive recommends Internet Explorer v7.0 or Mozilla Firefox v2.0.0 or later—with Flash v9.0 or later, which is required for viewing charts with dynamically updated HiveAP alarms and wireless client dataYour management system also needs a VT100 terminal emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems).Changing Network SettingsTo connect HiveManager to the network, you must first set the IP address/netmask of its MGT interface so that it is in the subnet to which you plan to cable it. To do this, you can use the startup wizard that is available through the console port.1. Connect the power cable to a 100 – 240-volt power source, and turn on HiveManager. The power switch is on the back panel of the device.2. Connect one end of an RS-232 serial cable to the serial port (or COM port) on your management system.3. Connect the other end of the cable to the male DB-9 console port on HiveManager.4. On your management system, run a VT100 emulation program using the following settings:• Bits per second (baud rate): 9600• Data bits: 8• Parity: none•Stop bits: 1• Flow control: none5. Log in by entering the default user name (admin) and password (aerohive).6. The HiveManager CLI shell launches and offers several options. To change network settings, enter 17. Follow the instructions to configure the IP address and netmask for the MGT (and LAN) interfaces, as well as the default gateway, host name and domain name of HiveManager, and its primary DNS server.When deciding to use one interface (MGT) or both (MGT and LAN), keep in mind that there are two main types of traffic to and from HiveManager:• HiveManager management traffic for admin access and SCP (Secure Copy) uploadsNote: HiveManager has two Ethernet interfaces—MGT and LAN. You can put just the MGT interface on the network and use it for all types of traffic, or you can use both interfaces—which must be in different subnets—and separate HiveManager management traffic (MGT) from HiveAP management traffic (LAN).Note: The default IP address/netmask for the MGT interface is 192.168.2.10/24. For the LAN interface, it is 192.168.3.10/24. The default gateway IP address is 192.168.2.1. If you only use the MGT interface, change the LAN interface network settings to 0.0.0.0/0. Do not assign it an IP address and netmask.
Chapter 7 Using HiveManager80 Aerohive• HiveAP management traffic for CAPWAP, SNMP monitoring and notifications, and SCP configuration, captive web portal file, and HiveOS firmware uploads to managed HiveAPsWhen you enable both interfaces, HiveManager management traffic uses the MGT interface while HiveAP management traffic uses the LAN interface, as shown in Figure 2.Figure 2 Using Both MGT and LAN InterfacesWhen only the MGT interface is enabled, both types of management traffic use it. A possible drawback to this approach is that the two types of management traffic cannot be separated into two different networks. For example, if you have an existing management network, you would not be able to use it for HiveManager management traffic. Both HiveManager and HiveAP management traffic would need to flow on the operational network because HiveManager would need to communicate with the HiveAPs from its MGT interface (see Figure 3). However, if the separation of both types of traffic is not an issue, then using just the MGT interface is a simple approach to consider.Figure 3 Using Just the MGT Interface8. After you finish configuring the network settings, return to the main menu, and reboot the HiveManager appliance by entering 5 (5 Reboot HM Appliance).You can now disconnect the serial cable.Note: To set static routes after you log in to the GUI, click HM Admin > HiveManager Settings > Routing > Add, set the destination IP address/netmask and gateway, and then click Apply.MGT10.1.2.8/24LAN10.1.1.8/24Switch Router Hives in different subnetsRouter10.1.3.0/2410.1.4.0/2410.1.5.0/2410.1.1.110.1.2.1Admin10.1.7.34 SCP Server 10.1.6.12HiveManagerEach hive contains multiple HiveAPs.Static Routes: HiveManager sends traffic destined for 10.1.6.0/24 to 10.1.2.1.HiveManager sends traffic destined for 10.1.7.0/24 to 10.1.2.1.Default Gateway: 10.1.1.1 (HiveManager sends traffic here when there are no specific routes to a destination.)MGT10.1.1.8/24LAN0.0.0.0/0 Switch Router Hives in different subnets10.1.3.0/2410.1.4.0/2410.1.5.0/2410.1.1.1Admin10.1.7.34 SCP Server 10.1.6.12HiveManagerEach hive contains multiple HiveAPs.Default Gateway: 10.1.1.1 (HiveManager sends all traffic to the default gateway.)
Deployment Guide 81 INSTALLING AND CONNECTING TO THE HIVEMANAGER GUIConnecting to the GUI through the MGT Interface 1. Connect Ethernet cables from the MGT interface and LAN interface—if you are using it—to the network.2. Connect an Ethernet cable from your management system to the network so that you can make an HTTPS connection to the IP address that you set for the MGT interface.3. Open a web browser and enter the IP address of the MGT interface in the address field. For example, if you changed the IP address to 10.1.1.8, enter this in the address field: https://10.1.1.8A login prompt appears.4. Type the default user name (admin) and password (aerohive) in the login fields, and then click Login.5. If prompted to enter a license key, click Browse, navigate to and select the text file containing the license key that Aerohive provided when HiveManager was purchased, and then click OK.You are now logged in to the HiveManager GUI. After logging in, you can check details about the license you installed on the HM Admin > License Management page.Note: If you ever forget the IP address of the MGT interface and cannot make an HTTP connection to HiveManager, make a serial connection to its console port and enter this command: ifconfig . The output displays data about the MGT interface (internally called "eth0"), including its IP address. The serial connection settings are explained in "Changing Network Settings" on page 79.
Chapter 7 Using HiveManager82 AerohiveINTRODUCTION TO THE HIVEMANAGER GUIUsing the HiveManager GUI, you can set up the configurations needed to deploy, manage, and monitor large numbers of HiveAPs. The configuration workflow is described in "HiveManager Configuration Workflow" on page 85. The GUI consists of several important sections, which are shown in Figure 4.Figure 4 Important Sections of the HiveManager GUISome convenient aspects that the HiveManager GUI offers are the ability to clone configurations, apply configurations to multiple HiveAPs at once, and sort displayed information. Brief overviews of these functions are presented in the following sections.Main Panel: The main panel contains the windows in which you set and view various parameters.Notifications: HiveManager displays a summary of new HiveAPs, rogue APs, rogue clients, and alarms detected on managed HiveAPs here. Clicking a displayed number opens the relevant page with more details.Menu Bar: The items in the menu bar open the major sections of the GUI. You can then use the navigation tree to navigate to more specific topics within the selected section.Navigation Tree: The navigation tree contains all the topics within the GUI section that you chose in the menu bar. Items you select in the navigation tree appear in the main panel.
Deployment Guide 83 INTRODUCTION TO THE HIVEMANAGER GUICloning ConfigurationsWhen you need to configure multiple similar objects, you can save time by configuring just the first object, cloning it, and then making slight modifications to the subsequent objects. With this approach, you can avoid re-entering repeated data.Figure 5 Cloning a HiveMultiselectingYou can select multiple objects to make the same modifications or perform the same operation to all of them at once.Figure 6 Selecting Multiple New HiveAPs1. Select2. ClickTo clone an object, select it in an open window, and then click the Clone button. Retain the settings you want to keep, and modify those you want to change.Here, you use the shift-click multiselection method to select a set of the topmost eight HiveAPs in the list; that is, you select the check box for the top HiveAP and hold down the SHIFT key while selecting the check box for the eighth HiveAP from the top.Select the check boxes to select multiple noncontiguous objects, or shift-click to select check boxes for multiple contiguous objects.Then click Accept to accept all the selected HiveAPs for HiveManager management, or click the Modify button to configure them with the same settings.
Chapter 7 Using HiveManager84 AerohiveSorting Displayed DataYou can control how the GUI displays data in the main panel by clicking a column header. This causes the displayed content to reorder itself alphanumerically or chronologically in either ascending or descending order. Clicking the header a second time reverses the order in which the data is displayed.Figure 7 Sorting Event Log Entries by HiveAP Host Name and then ChronologicallyIndicates that the list appears in descending order from the top Indicates that the list appears in ascending order from the bottomBy default, displayed objects are sorted alphanumerically from the top by name. If you click the name again, the order is reversed; that is, the objects are ordered alphanumerically from the bottom.By clicking the heading of a column, you can reorder the display of objects either alphanumerically or chronologically, depending on the content of the selected column. Here you reorder the data chronologically.
Deployment Guide 85 HIVEMANAGER CONFIGURATION WORKFLOWHIVEMANAGER CONFIGURATION WORKFLOWAssuming that you have already installed your HiveAPs, uploaded maps (see "Setting Up Topology Maps" on page 91), accepted the HiveAPs for management, and decided on the features and settings you want to use, you are now ready to start configuring the HiveAPs through HiveManager1. You can configure numerous objects, some of which might need to reference other objects. An efficient configuration strategy is to first define any objects that you will later need to use when configuring others. The typical workflow, shown in Figure 8, proceeds like this:1. Define network objects. You can then reference them when defining other parts of the configuration. If you do not plan to use network objects, you can skip this step.2. Configure various features.3. Define radio profiles (or use default settings).4 and 5. Compile the features from step 2 into a WLAN policy, assign the radio profiles and WLAN policy to one or more HiveAPs, and then push the configurations to the physical devices on the network.Figure 8 Configuration Workflow1. When HiveAPs are in the same subnet as HiveManager, they can use CAPWAP (Control and Provisioning of Wireless Access Points) to discover HiveManager on the network. CAPWAP works within a layer-2 broadcast domain and is enabled by default on all HiveAPs. If the HiveAPs and HiveManager are in different subnets, then you can use one of several approaches to enable HiveAPs to connect to HiveManager. For information about these options, see "How HiveAPs Connect to HiveManager" on page 95.MAC FiltersUser ProfilesSSIDsMgt Services AAA SettingsRadio Profiles WLAN PolicyHiveHiveManagerManaged HiveAP1. If you need to reference network objects in another part of the configuration, you must define them first. Otherwise, this step is unnecessary.4. Compose a WLAN policy by referencing items set in Step 2.2. Use default settings or configure new settings for various features that, when combined, constitute a WLAN policy:• Mobility policies• Firewall policies• QoS traffic classification and marking•MAC Filters•SSIDs• User profiles• Management services (DNS, NTP, SNMP, syslog, location)• AAA settings (for user authentication using IEEE 802.1X)• Wireless IDS policy•Hive1234 5QoS Traffic Classification and Marking 3.

Chapter 7 Using HiveManager86 AerohiveUPDATING SOFTWARE ON HIVEMANAGERYou can update the software running on HiveManager from either a local directory on your management system or an SCP (Secure Copy) server. If you download an image and save it to a local directory, you can load it from there. If you save the image to an SCP server, you can direct HiveManager to log in and load it from a directory there.1. If you do not yet have an account on the Aerohive Support portal, send an email request to (support@aerohive.com) to set one up.2. When you have login credentials, visit www.aerohive.com/support/login, and log in.3. Navigate to the software image that you want to load onto HiveManager (Customer Support > Software Downloads > HiveManager software images) and download the file.4. Save the HiveManager image file to a local directory or an SCP server.5. Log in to HiveManager and navigate to HM Admin > HiveManager Operations > Update Software.6. To load files from a directory on your local management system, choose either Update and clear alarm and event logs or Full update (to keep existing log entries after the upgrade), and then enter the following:• File from local host: (select); type the directory path and a file name; or click Browse, navigate to the software file, and select it.or To load a file from an SCP server:• File from remote server: (select)• IP Address: Enter the IP address of the SCP server.• SCP Port: Enter the port number of the SCP server (the default port number for SCP is 22).• File Path: Enter the directory path and HiveManager software file name. If the file is in the root directory of the SCP server, you can simply enter the file name.• User Name: Type a user name with which HiveManager can access the SCP server.• Password: Type a password with which HiveManager can use to log in securely to the SCP server.7. To save the new software and reboot HiveManager, click OK.
Deployment Guide 87 UPDATING HIVEOS FIRMWAREUPDATING HIVEOS FIRMWAREHiveManager makes it easy to update HiveOS firmware running on managed HiveAPs. First, you obtain new HiveAP firmware from Aerohive Support and upload it onto HiveManager. Then you push the firmware to the HiveAPs and activate it by rebooting them.1. Log in to the Aerohive Support portal to obtain a new HiveOS image.2. Save the HiveOS image file to a directory on your local management system or network.3. Log in to HiveManager and navigate to Configuration > HiveAP File Management.4. On the HiveAP Files page, select HiveOS Image for the file type, enter one of the following—depending on how you intend to upload the HiveOS image file to HiveManager—and then click OK:To load a HiveOS image file from a directory on your local management system:• Local File: (select); type the directory path and image file name, or click Browse, navigate to the image file, and select it.To load a HiveOS image file from an SCP server:• SCP Server: (select) IP Address : Enter the IP address of the SCP server.• SCP Port: Enter the port number of the SCP server (the default port number for SCP is 22).• File Path: Enter the path to the HiveOS image file and the file name. If the file is in the root directory of the SCP server, you can simply enter the file name.• User Name: Type a user name with which HiveManager can access the SCP server.• Password: Type a password that HiveManager can use to log in securely to the SCP server.5. Click Access Points > Managed HiveAPs.6. In the Managed HiveAPs window, select one or more HiveAPs, and then click Update > Upload and Activate SW Image.The Upload and Activate SW Image dialog box appears.7. Enter the following, and then click Upload:• From the HiveOS Image drop-down list, select the image that you want to load onto managed HiveAPs.• In the Activation Time section, select one of the following options, depending on when you want to activate the software—by rebooting the HiveAPs—after HiveManager finishes loading it:•Activate at: Select and set the time at which you want the HiveAPs to activate the software. To use this option accurately, make sure that both HiveManager and managed HiveAP clocks are synchronized.•Activate after: Select to load the firmware on the selected HiveAPs and activate it after a specified interval. The range is 0 – 3600 seconds; that is, immediately to one hour. The default is 5 seconds.Note: When upgrading both HiveManager software and HiveOS firmware, do so in this order:•Upgrade HiveManager (HiveManager can manage HiveAPs running the current version of HiveOS and also previous versions).•Upload the new HiveOS firmware to the managed HiveAPs, and reboot them to activate it.•Reload the HiveOS configurations to the managed HiveAPs—even if nothing in the configurations has changed—and reboot them to activate the configuration that is compatible with the new HiveOS image.Note: To delete an old image file, select the file in the "Available Images" list, and then click Remove.
Chapter 7 Using HiveManager88 Aerohive•Activate at next reboot: Select to load the software and not activate it. The loaded software gets activated the next time the HiveAP reboots.• Select the check box for each HiveAP whose software you want to update.Updating HiveAPs in a Mesh EnvironmentWhen updating hive members in a mesh environment, be careful of the order in which the HiveAPs reboot. If a portal completes the upload and reboots before a mesh point beyond it completes its upload—which most likely would happen because portals receive the uploaded content first and then forward it to mesh points—the reboot will interrupt the data transfer to the mesh point. This can also happen if a mesh point linking HiveManager to another mesh point reboots before the more distant mesh point completes its upload. As a result of such an interruption, the affected mesh point receives an incomplete firmware or configuration file and aborts the update.Figure 9 HiveAPs in a Mesh EnvironmentTo avoid the reboot of an intervening HiveAP from interfering with an ongoing upload to a mesh point beyond it, allow enough time for the firmware to reach the farthest mesh points before activating the firmware. After all the HiveAPs have the firmware, rebooting any HiveAPs between them and HiveManager becomes inconsequential.Note: When choosing which option to use, consider how HiveManager connects to the HiveAPs it is updating. See "Updating HiveAPs in a Mesh Environment".Note: A mesh point is a hive member that uses a wireless backhaul connection to communicate with the rest of the hive. HiveManager manages mesh points through another hive member that acts as a portal, which links mesh points to the wired LAN.= Wired Link= Wireless LinkHiveManager Switch HiveAP(Portal) HiveAP(Mesh Point 1) HiveAP(Mesh Point 2)When updating HiveAPs in a mesh environment, the HiveManager communicates with mesh points through their portal and, if there are any intervening mesh points, through them as well. While updating HiveAPs in such an environment, it is important to keep the path from the HiveManager to all HiveAPs clear so that the data transfer along that path is not disrupted. Therefore, when updating a firmware image or configuration on HiveAPs in a mesh environment, make sure that the portal or a mesh point closer to the portal does not reboot before the upload to a mesh point farther away completes.
Deployment Guide 89Chapter 8 HiveManager Configuration ExamplesThe following examples in this chapter show how to install over 70 HiveAPs at three locations in a corporate network, use HiveManager to create configurations for them, and then push the configurations to them over the network. The high-level deployment scheme is as follows:The general design of the deployment is shown in Figure 1.Figure 1 Deployment OverviewYou can look at any of the following examples individually to study how to configure a specific feature or view all of them sequentially as a set to study the workflow for deploying large numbers of HiveAPs and configuring them through HiveManager.Headquarters - Building 1 (HQ-B1) Headquarters - Building 2 (HQ-B2) Branch Office (Branch1)32 HiveAPs 32 HiveAPs 8 HiveAPs1 Hive (hive1) 1 Hive (hive2) 1 Hive (hive3)1 WLAN policy (WLANpolicy-hq1) 1 WLAN policy (WLANpolicy-hq2) 1 WLAN policy (WLANpolicy-branch1)x 8 Floors 4 HiveAPs per Floor x 8 Floors 2 HiveAPs per Floor x 4 FloorsCorporate Headquarters Branch Office64 HiveAPs Total8 HiveAPs TotalBranch1HQ-B1 HQ-B2WLANpolicy-hq1Hive1WLANpolicy-hq2Hive2WLANpolicy-branch1Hive3VPN TunnelHiveManager(in “HQ-B1”)
