10/100/1000Base-T Twisted Pair Ports

The switches have 24 or 48 10/100/1000Base-T ports.

Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set

manually using the management software or automatically with Auto-

Negotiation (IEEE 802.3u), the default setting.

Note

The ports must be set to Auto-Negotiation to function at 1000 Mbps

and are not compatible with devices that are not IEEE 802.3u

compliant.

Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The

duplex mode of a port, like port speed, may be set manually using the

management software or automatically with Auto-Negotiation (IEEE

802.3u), the default setting.

The speed and duplex mode settings of a port may be set independently

of each other. For example, a port may be configured such that its speed

is set manually while its duplex mode is established through Auto-

Negotiation.

Note

A switch port should not use Auto-Negotiation to set its duplex mode

if it is connected to a network device that does not support Auto-

Negotiation for 10 or 100 Mbps operation and has a fixed duplex

mode of full-duplex. Otherwise, a duplex-mode mismatch may occur

in which a switch port and a network device operate at different

duplex modes. The duplex modes of switch ports that are connected

to network devices that do not support Auto-Negotiation should be

set manually through the management software.

Wiring

Configuration

The wiring configuration of a port operating at 10 or 100 Mbps can be MDI

or MDI-X. The wiring configurations of a switch port and a network device

connected with straight-through twisted pair cabling have to be opposite,

such that one device is using MDI and the other MDI-X. For instance, a

switch port has to be set to MDI-X if it is connected to a network device set

to MDI.

You may set the wiring configurations of the ports manually or let the

switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab-

compliant). This feature enables the switch to automatically negotiate with

network devices to establish their proper settings.

Chapter 1: Overview

The MDI and MDI-X settings do not apply when ports are operating at

1000 Mbps.

Maximum

Distance

The ports have a maximum operating distance of 100 meters (328 feet).

Cable

Requirements

The cable requirements of the ports are given in Table 1.

Note

For the cable requirements for the ports on the AT-x510-28GPX and

AT-x510-52GPX Switches for PoE devices, refer to Table 3 on

page 26.

Port Pinouts Refer to Table 18 on page 87 and Table 19 on page 88 for the port pinouts

of the 10/100/1000Base-T twisted pair ports.

Ethernet (PoE) on the 10/100/1000Base-T ports. PoE is used to supply

power to network devices over the same twisted pair cables that carry the

network traffic.

The main advantage of PoE is that it can make it easier to install a

network. The selection of a location for a network device is often limited by

whether there is a power source nearby. This often limits equipment

placement or requires the added time and cost of having additional

electrical sources installed. But with PoE, you can install PoE-compatible

devices wherever they are needed without having to worry about whether

there are power sources nearby.

A device that provides PoE to other network devices is referred to as

power sourcing equipment (PSE). The AT-x510-28GPX and AT-x510-

52GPX Switches act as PSE units by adding DC power to the network

cable, thus functioning as a central power source for other network

devices.

Devices that receive their power from a PSE are called powered devices

(PD). Examples include wireless access points, IP telephones, webcams,

and even other Ethernet switches.

The switch automatically determines whether or not a device connected to

a port is a powered device. Ports that are connected to network nodes that

are not powered devices (that is, devices that receive their power from

another power source) function as regular Ethernet ports, without PoE.

The PoE feature remains activated on the ports but no power is delivered

to the devices.

PoE Standards The AT-x510-28GPX and AT-x510-52GPX Switches support these PoE

standards:

PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the

switch port to support powered devices that require up to 12.95

watts.

PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at

the switch port to support powered devices that require up to 25.5

watts.

Powered Device

Classes

Powered devices are grouped into the five classes listed in Table 2 on

page 26. The classes are based on the amount of power the devices

require. The switches support all five classes.

The cable requirements for ports operating at 1000Mbps are given in

Table 4.

Power Budget The AT-x510-28GPX and AT-x510-52GPX Switches have a power budget

of 370 watts. This is the maximum amount of power the switches can

provide at one time to the powered devices.

The AT-x510-28GPX and AT-x510-52GPX Switches have two power

supplies. Each power supply is responsible for providing 185 watts, or half,

of the power budget. Both power supplies must be connected to AC power

sources for the switch to provide the full 370 watts. The power budget is

reduced to 185 watts if only one power supply is connected to a power

source.

The power requirements of the PoE devices determine the maximum

number of devices the switch can support at one time. So long as the total

power requirements of the powered devices is less than the power budget

of the switch, the switch can supply power to all the devices. But if the total

power requirements exceed the power budget, the switch denies power to

one or more ports using a mechanism referred to as port prioritization.

To determine whether the power requirements of the PoE devices you

plan to connect to the switch exceed its power budget, refer to their

documentation for their power requirements and add the requirements

together. The switch should be able to power all of the devices

simultaneously as long as the total is below its power budget. If the total

exceeds the available power budget, you should consider reducing the

number of PoE devices so that all of the devices receive power.

Otherwise, the switch powers a subset of the devices, based on port

prioritization.

The switch can handle different power requirements on different ports.

This enables you to connect different classes of PoE equipment to the

ports on the switch.

Port

Prioritization

If the power requirements of the powered devices exceed the switch’s

power budget, the switch denies power to some ports based on a system

called port prioritization. You may use this mechanism to ensure that

powered devices critical to the operations of your network are given

preferential treatment by the switch in the distribution of power should the

demands of the devices exceed the available capacity.

There are three priority levels:

Critical

High

Low

Ports set to the Critical level, the highest priority level, are guaranteed

power before any of the ports assigned to the other two priority levels.

Ports assigned to the other priority levels receive power only if all the

Critical ports are receiving power. Ports that are connected to your most

critical powered devices should be assigned to this level. If there is not

enough power to support all the ports set to the Critical priority level,

power is provided to the ports based on port number, in ascending order.

The High level is the second highest level. Ports set to this level receive

power only if all the ports set to the Critical level are already receiving

power. If there is not enough power to support all of the ports set to the

High priority level, power is provided to the ports based on port number, in

ascending order.

The lowest priority level is Low. This is the default setting. Ports set to this

level only receive power if all of the ports assigned to the other two levels

are already receiving power. As with the other levels, if there is not enough

power to support all of the ports set to the Low priority level, power is

provided to the ports based on port number, in ascending order.

Power allocation is dynamic. Ports supplying power to powered devices

may cease power transmission if the switch’s power budget is at

maximum usage and new powered devices, connected to ports with

higher priorities, become active.

You can use port prioritization on dual power supply PoE switches to

protect your important networking devices from loss of power should one

x510 Series Installation Guide for Stand-alone Switches

of the power supplies fail or lose power. If you limit the power requirements

of the critical devices connected to a switch to less than 185 watts, the

PoE power provided by a single power supply, a switch will have sufficient

power to support the critical devices even if it has only one functional

power supply.

Wiring

Implementation

The IEEE 802.3af standard defines two methods for the delivery of DC

power over twisted pair cable by a PSE, such as the switch, to PDs. These

methods, known as modes A and B, identify the wires within the cable that

carry the DC power from the PSE to a PD.

Twisted pair cabling typically consists of eight wires. With 10Base-T and

100Base-TX devices, the wires connected to pins 1, 2, 3, and 6 on the RJ-

45 connectors carry the network traffic while the wires connected to pins 4,

5, 7, and 8 are unused. With 1000Base-T devices, all eight wires are used

to carry network data.

It takes four wires to deliver DC power to a PD. With Mode A, the power is

delivered on pins 1, 2, 3, and 6. These are the same pins in 10Base-T and

100Base-TX devices that carry the network data. With mode B, the power

is provided over the spare wires.

The ports on the AT-x510-28GPX and AT-x510-52GPX Switches deliver

the power using pins 1, 2, 3, and 6, which corresponds to mode A in the

IEEE 802.3af standard. Powered devices that comply with the IEEE

802.3af standard are required to support both power delivery methods.

Legacy devices that do not comply with the standard will work with the

switch if they are powered on pins 1, 2, 3, and 6.

Chapter 1: Overview

SFP+ Slots

The switches have four SFP+ slots that support the following types of SFP

1000Mbps and SFP+ 10Gbps transceivers:

1000Base-SX/LX SFP transceivers

Single-port BiDi 1000Base-LX SFP transceivers

1000Base-ZX SFP transceivers

10Gbps, 10GBase-SR/LR fiber optic transceivers

10Gbps AT-SP10TW direct connect twinax cables with SFP+

transceiver-style connectors

You may use the transceivers to connect switches to other network

devices over large distances, build high-speed backbone networks

between network devices, or connect high-speed devices, such as

servers, to your network.

The switches support a variety of short and long distance SFP and SFP+

modules. For a list of supported SFP modules, contact your Allied Telesis

representative or visit our web site.

Note

SFP+ slots 27 and 28 on the AT-x510-28GTX and AT-x510-28GPX

Switches and slots 51 and 52 on the AT-x510-52GTX and AT-x510-

52GPX Switches are initially configured as stacking slots for the

VCStack feature. If you intend to use the switch as a stand-alone

unit, you must disable the VCStack feature before you can use the

slots with standard SFP or SFP+ transceivers. The configuration

instructions are provided later in this guide, in “Configuring the

Switch for Stand-alone Operations” on page 74.

x510 Series Installation Guide for Stand-alone Switches

Stacking SFP+ Slots

Two of the four SFP+ slots on the front panel of the switch can be used

with special stacking transceivers to create a VCStack of up to four

switches. The switches of a VCStack act as a single virtual unit. They

synchronize their actions so that switching operations, like spanning tree

protocols, virtual LANs, and static port trunks, span across all the units and

ports. The two main advantages of stacks are:

You can manage multiple units simultaneously, which can simplify

network management.

You have more flexibility in how you configure some of the

features. For instance, a static port trunk on a stand-alone switch

has to consist of ports from the same switch. In contrast, a static

trunk on a stack may consist of ports from different switches in the

same stack.

The slots for the stacking transceivers are SFP+ slots 27 and 28 on the 28-

port switches and slots 51 and 52 on the 52-port switches.

The stacking transceivers are listed in Table 5.

Note

This guide explains how to install the devices as stand-alone units.

For instructions on how to install the switches in a stack, refer to the

x510 Series Installation Guide for Virtual Chassis Stacking.

Chapter 1: Overview

eco-friendly Button

The eco-friendly button on the front panel of the switch is used to toggle

the port LEDs on or off. You might turn off the LEDs to conserve electricity

when you are not monitoring the device. You can also toggle the LEDs

with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in

the Global Configuration mode of the command line interface. The switch

is said to be operating in a low power mode when the LEDs are turned off.

Operating the switch in the low power mode with the LEDs turned off does

not interfere with the network operations of the device.

The management software on the switch has a command that blinks the

LEDs so that you can quickly and easily identify a specific unit among the

devices in an equipment rack. It is the FINDME command. The command

works on the switch even if you turned off the LEDs with the eco-friendly

button or NO ECOFRIENDLY LED command.

The Switch ID LED is always on, but it displays different information

depending on whether the LEDs are on or off. When the LEDs are on, the

ID LED displays the ID number of the switch. When the switch is operating

in the low power mode with the LEDs off, the ID LED indicates whether the

switch is a stand-alone unit or the master or member switch of a VCStack,

as detailed in Figure 12 on page 40.

Note

Before checking or troubleshooting the network connections to the

ports on the switch, you should always check to be sure that the

LEDs are on by either pressing the eco-friendly button or issuing the

ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in

the Global Configuration mode of the command line interface.

USB Port

The management panel has a USB port. You may use the port to store

configuration files on flash drives and to restore configuration files to

switches whose settings have been lost or corrupted, or to quickly

configure replacement units. You may also use the port and flash drives to

update the management firmware on the switches.

The port is USB2.0 compatible.

Chapter 1: Overview

Console Port

The Console port is used to establish a management session with the

switch to configure its features and parameter settings. This type of

management uses serial RS-232 and is commonly referred to as local or

out-of-band management because it is not conducted over your network.

To perform local management, you must be at the location of the switch

and must use the management cable included with the switch.

To establish a local management session with the switch, connect a

terminal or a personal computer with a terminal emulation program to the

Console port, which has an RJ-45 style (8P8C) connector, using the

provided management cable. The cable has RJ-45 RJ-style (8P8C) and

DB-9 (D-sub 9-pin) connectors.

The Console port is set to the following specifications:

Default baud rate: 9600 bps (Range is 9600 to 115200 bps)

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Note

These settings are for a DEC VT100 or ANSI terminal, or an

equivalent terminal emulation program.

Power Supplies

The x510 Series switches have two AC power supplies with separate AC

connectors on the back panels. The power supplies, which are not field-

replaceable, provide a switch with power redundancy and protect against

interruptions to network operations in the event one of the power supplies

loses power or fails. Power redundancy is available only when both AC

connectors on a switch are connected to power sources.

The AT-x510-28GPX and AT-x510-52GPX Switches have a PoE budget

of 370 watts when both power supplies are active and 185 watts when only

one power supply is active. For further information, refer to “Power

sure that the rack is safely secured so that it will not tip over.

Devices in a rack should be installed starting at the bottom, with

the heavier devices near the bottom of the rack.

If you plan to install the switch on a table, check to be sure that the

table is level and stable.

The power outlet should be located near the switch and be easily

accessible.

The site should allow for easy access to the ports on the front of

the switch, so that you can easily connect and disconnect cables,

and view the port LEDs.

The site should allow for adequate air flow around the unit and

through the cooling vents on the front and rear panels. (The

ventilation direction in units that have a cooling fan is from front to

back, with the fan on the back panel drawing the air out of the unit.)

The site should not expose the switch to moisture or water.

The site should be a dust-free environment.

The site should include dedicated power circuits or power

conditioners to supply reliable electrical power to the network

devices.

Do not install the switch in a wiring or utility box because it will

overheat and fail from inadequate airflow.

Warning

Switches should not be stacked on top of one another on a table or

desktop because that could present a personal safety hazard if you

need to move or replace switches.

You may install the switch on a table or desktop. Here are the guidelines

to selecting a site:

The table should be level and stable.

The power outlet should be located near the switch and be easily

accessible.

The site should allow for easy access to the ports on the front of

the switch, so that you can easily connect and disconnect cables,

Chapter 4

Cabling the Networking Ports

This chapter contains the following procedures:

“Cabling the Twisted Pair Ports” on page 60

“Installing SFP and SFP+ Transceivers” on page 62

Chapter 4: Cabling the Networking Ports

Cabling the Twisted Pair Ports

Here are the guidelines to cabling the 10/100/1000Base-T twisted pair

ports:

The cable specifications for the 10/100/1000Base-T twisted pair

ports are listed in Table 1 on page 24.

The connectors on the cables should fit snugly into the ports, and

the tabs should lock the connectors into place.

The default setting for the wiring configurations of the ports is auto-

MDI/MDI-X. The default setting is appropriate for switch ports that

are connected to 10/100Base-TX network devices that also

support auto-MDI/MDI-X.

The default auto-MDI/MDI-X setting is not appropriate for switch

ports that are connected to 10/100Base-TX network devices that

do not support auto-MDI/MDI-X and have a fixed wiring

configuration. For switch ports connected to those types of network

devices, you should disable auto-MDI/MDI-X and set the wiring

configurations manually.

The appropriate MDI/MDI-X setting for a switch port connected to a

10/100Base-TX network device with a fixed wiring configuration

depends on the setting of the network device and whether the

switch and network device are connected with straight-through or

crossover cable. If you are using straight-through twisted pair

cable, the wiring configurations of a port on the switch and a port

on a network device must be opposite each other, such that one

port uses MDI and the other MDI-X. For example, if a network

device has a fixed wiring configuration of MDI, you must disable

auto-MDI/MDI-X on the corresponding switch port and manually

set it to MDI-X. If you are using crossover twisted pair cable, the

wiring configurations of a port on the switch and a port on a

network device must be the same.

The default speed setting for the ports is Auto-Negotiation. This

setting is appropriate for ports connected to network devices that

also support Aut-Negotiation.

The default speed setting of Auto-Negotiation is not appropriate for

ports connected to 10/100Base-TX network devices that do not

support Auto-Negotiation and have fixed speeds. For those switch

ports, you should disable Auto-Negotiation and set the port’s

speed manually to match the speeds of the network devices.

The 10/100/1000Base-T ports must be set to Auto-Negotiation, the

default setting, to operate at 1000Mbps.

The default duplex mode setting for the ports is Auto-Negotiation.

This setting is appropriate for ports connected to network devices

that also support Auto-Negotiation for duplex modes.

x510 Series Installation Guide for Stand-alone Switches

The default duplex mode setting of Auto-Negotiation is not

appropriate for ports connected to network devices that do not

support Auto-Negotiation and have a fixed duplex mode. You

should disable Auto-Negotiation on those ports and set their duplex

modes manually to avoid the possibility of duplex mode

mismatches. A switch port using Auto-Negotiation defaults to half-

duplex if it detects that the end node is not using Auto-Negotiation,

which can result in a mismatch if the end node is operating at a

fixed duplex mode of full-duplex.

Do not attach cables to ports of static or LACP port trunks until

after you have configured the trunks on the switch. Otherwise, the

ports will form network loops that can adversely affect network

performance.

Chapter 4: Cabling the Networking Ports

Installing SFP and SFP+ Transceivers

This section contains guidelines and procedures for installing SFP and

SFP+ transceivers. The installation procedures are listed here:

“Installing SFP Modules in the AT-x510-28GSX Switch” on page 63

“Installing SFP and SFP+ Modules” on page 66

Here are general installation guidelines for SFP and SFP+ transceivers:

SFP and SFP+ transceivers are hot-swappable. You may install

them while the chassis is powered on.

Your Allied Telesis sales representative can provide you with a list

of supported transceivers for the units.

The operational specifications and fiber optic cable requirements

of the transceivers are provided in the documents included with the

devices.

You should install a transceiver before connecting the fiber optic

cable.

Fiber optic transceivers are dust sensitive. Always keep the plug in

the optical bores when a fiber optic cable is not installed, or when

you store the transceiver. When you do remove the plug, keep it

for future use.

Unnecessary removal and insertion of a transceiver can lead to

premature failure.

Warning

A transceiver can be damaged by static electricity. Be sure to

observe all standard electrostatic discharge (ESD) precautions,

such as wearing an antistatic wrist strap, to avoid damaging the

device.

Note

SFP+ slots 27 and 28 on the 28-port switches and slots 51 and 52

on the 52-port switches are initially configured as stacking slots for

the VCStack feature. If you intend to use the switch as a stand-alone

unit, you must disable the VCStack feature before you can use the

slots with standard SFP or SFP+ transceivers. For instructions, refer

to Chapter 5, “Powering On the Switch” on page 69.

Configuring the Switch for Stand-alone Operations

After the switch has initialized its management software, examine the

switch ID LED on the front panel and do one of the following:

If the LED is displaying “0,” the installation procedure is complete.

The switch is now ready for network operations as a stand-alone

unit. Refer to the Software Reference for x510 Series Switches,

AlliedWare Plus Operating System, for instructions on how to

configure the operating parameters.

If the LED is displaying a number other than “0,” perform the

following procedures to disable the VCStack feature.

You can disable the VCStack feature from a local management session of

the switch using the Console port. To start a local management session,

go to “Starting a Local Management Session,” next.

Caution

You have to reset the switch to disable the VCStack feature. Some

network traffic may be lost if the device is already connected to a live

network.

Note

The initial management session of the switch must be from the

Console port.

Starting a Local

Management

Session

This procedure requires a terminal or a terminal emulator program and

the management cable that comes with the switch. To start a local

management session on the switch, perform the following procedure:

1. Connect the RJ-45 connector on the management cable to the

Console port on the front panel of the switch, as shown in Figure 33 on

page 75.

x510 Series Installation Guide for Stand-alone Switches

Figure 33. Connecting the Management Cable to the Console Port

2. Connect the other end of the cable to an RS-232 port on a terminal or

PC with a terminal emulator program.

3. Configure the terminal or terminal emulator program as follows:

Baud rate: 9600 bps (The baud rate of the Console Port is

adjustable from 1200 to 115200 bps. The default is 9600 bps.)

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Note

The port settings are for a DEC VT100 or ANSI terminal, or an

equivalent terminal emulator program.

4. Press Enter.

You are prompted for a user name and password.

5. When prompted for a user name, go to “Disabling VCStack” on

page 76.

Chapter 5: Powering On the Switch

Disabling

VCStack

To disable the VCStack feature to use the switch as stand-alone unit,

perform the following procedure:

Caution

Disabling the VCStack feature requires resetting the switch. If the

switch is already connected to a live network, some network traffic

may be lost.

1. When prompted, enter a user name and password to log on the

switch. If this is the initial management session of the switch, enter

“manager” as the user name and “friend” as the password. The user

name and password are case sensitive.

The local management session starts when the User Exec mode

prompt, shown in Figure 34. is displayed.

Figure 34. User Exec Mode Prompt

Note

The User Exec mode is the first level in the command mode

interface. For complete information on the modes and commands,

refer to the Software Reference for x510 Series Switches,

AlliedWare Plus Operating System from www.alliedtelesis.com.

2. Enter the SHOW STACK command to display the status of the

VCStack feature. Figure 35 is an example of the command.

Figure 35. SHOW STACK Command

3. Review the following items:

If the Operational Status is “Stacking Hardware Disabled,” the

VCStack feature is already disabled on the switch and the SFP+

stacking slots may be used with regular SFP or SFP+ transceivers.

x510 Series Installation Guide for Stand-alone Switches

If the Operational Status is “Standalone Unit,” as shown in Figure

35 on page 76, the VCStack feature is active on the unit. You must

disable it by performing the steps in the rest of this procedure

before you can use the SFP+ stacking slots with regular SFP or

SFP+ transceivers. The reason the status says “standalone” is

because the switch considers itself a stack of one switch.

4. Move to the Global Configuration mode by entering the ENABLE and

CONFIGURE TERMINAL commands, as shown in Figure 36.

Figure 36. Moving to the Global Configuration Mode

5. To. disable the VCStack feature on the switch, enter the NO STACK

ENABLE command, which has this format:

no stack

enable

The ID parameter is the ID number of the switch, displayed on the ID

LED. Replace the parameter with whatever number is on the ID LED.

For example, if the ID number of the switch is 1, the default value,

enter the command as follows:

awplus(config)# no stack 1 enable

This confirmation prompt in Figure 37 is displayed.

Figure 37. Confirmation Prompt for the NO STACK ENABLE Command

6. Type Y to disable VCStack on the switch or N to cancel the procedure.

7. Enter the EXIT command to return to the Privileged Exec mode, as

shown in Figure 38.

Figure 38. Returning to the Privileged Exec Mode

8. Enter the WRITE command to save your change in the configuration

file. The switch displays the confirmation prompt in Figure 39 on page

78.

Chapter 5: Powering On the Switch

Figure 39. Saving the Changes with the WRITE Command

9. Enter the REBOOT command to reboot the switch.

10. At the confirmation prompt, type “Y” for yes.

11. Wait for the switch to initialize its management software and

afterwards examine the Switch ID LED. The switch is ready for normal

network operations as a stand-alone unit when its ID number is “0.”

Refer to the Software Reference for x510 Series Switches, AlliedWare

Plus Operating System, for instructions on how to configure the

operating parameters. If the number is not “0,” repeat this procedure.

Confirming the

Status of the

VCStack Feature

Another way to confirm that VCStack is disabled on the switch is by

displaying the status of the last two SFP+ slots on the switch. These are

slots 27 and 28 on the 28-port switches and slots 51 and 52 on the 52-port

switches. If VCStack is disabled, you should be able to display the status

of the slots even when they do not have transceivers. If VCStack is not

disabled, the switch displays a message that it cannot find the slots. To

view the status of the stacking slots, perform this procedure:

1. Start a management session on the switch. For directions, refer to

“Configuring the Switch for Stand-alone Operations” on page 74.

2. Log on to the switch. The default user name is “manager” and the

password is “friend”.

3. From either the User Exec mode or Privileged Exec mode, enter the

SHOW INTERFACE command to display the status of one of the last

two SFP+ slots on the switch. For example, for the AT-x510-28GTX

Switch, enter this command to view the status of slot 27:

show interface port1.0.27

4. For the AT-x510-52GTX Switch, enter this command to view the status

of slot 51:

show interface port1.0.51

If VCStack is disabled, the switch displays the status of the designated

slot. An example is shown in Figure 40 on page 79.

Specifying Ports in the Command Line Interface for Stand-alone

Switches

The command line interface in the management software on the switch

has a parameter that you use to specify the individual ports. The

parameter is the PORT parameter and Figure 42 shows its format.

Figure 42. PORT Parameter in the Command Line Interface

The first number is the switch’s ID number. The ID number for stand-alone

switches is not the value 0 displayed on the Switch ID LEDs. Rather, it is

1. Be sure to enter 1, not 0, as the ID number in the PORT parameter

when configuring ports on stand-alone switches.

The module ID value is used with multi-module products. This value does

not apply to the x510 Series switches and should always be 0.

The third value is a port number on the switch. You may specify only one

port number in a PORT parameter, but you may specify more than one

PORT parameter in many commands where the parameter is supported.

Here is an example of the PORT parameter on a stand-alone switch. It

uses the INTERFACE command to enter the Port Interface mode for ports

15 and 17:

awplus> enable

awplus# configure terminal

awplus(config)# interface port1.0.15,port1.0.17

For instructions on the command line interface and the PORT parameter,

Problem 1: The Switch ID LED on the front of the switch is off.

Solutions: The unit is not receiving power. Try the following:

Verify that the power cord is securely connected to the power

source and to the AC connector on the back panel of the switch.

Verify that the power outlet has power by connecting another

device to it.

Try connecting the unit to another power source.

Try a different power cord.

Verify that the voltage from the power source is within the required

levels for your region.

Problem 2: All of the port LEDs are off even though the ports are

connected to active network devices.

Solution: The switch may be operating in the low power mode. To toggle

on the LEDs, press the eco-friendly button on the front panel of the switch.

You may also toggle the LEDs off and on with the ECOFRIENDLY LED

and NO ECOFRIENDLY LED commands in the command line interface.

Problem 3: A twisted pair port on the switch is connected to a network

device but the port’s LINK/ACT LED is off.

Solutions: The port is unable to establish a link to a network device. Try

the following:

Verify that the port is connected to the correct twisted pair cable.

This is to eliminate the possibility that the port is connected to the

wrong network device.

Verify that the network device connected to the twisted pair port is

powered on and is operating properly.

Chapter 6: Troubleshooting

Try connecting another network device to the twisted pair port with

a different cable. If the twisted pair port is able to establish a link,

then the problem is with the cable or the other network device.

Verify that the twisted pair cable does not exceed 100 meters (328

feet).

Verify that you are using the appropriate category of twisted pair

cable. The cable types are listed in Table 1 on page 24 for the 10/

100/1000Base-T ports.

Note

A 1000Base connection may require five to ten seconds to establish

a link.

Problem 4: The LINK/ACT LED for an SFP or SFP+ transceiver is off.

Solutions: The fiber optic port on the transceiver is unable to establish a

link to a network device. Try the following:

Verify that the remote network device connected to the fiber optic

port is operating properly.

Verify that the fiber optic cable is securely connected to the port on

the SFP or SFP+ module and to the port on the remote network

device.

Check that the transceiver is fully inserted in the slot.

If you are using SFP+ slots 27 or 28 on the 28-port switches or

slots 51 and 52 on the 52-port switches, check that VCStack is

disabled on the switch. The VCStack feature has to be disabled

before you can use these slots for regular SFP or SFP+

transceivers. For instructions, refer to “Configuring the Switch for

Stand-alone Operations” on page 74

Verify that the operating specifications of the fiber optic ports on

the transceiver and remote network device are compatible.

Verify that the correct type of fiber optic cabling is being used.

Verify that the port is connected to the correct fiber optic cable.

This is to eliminate the possibility that the port is connected to the

wrong remote network device.

Try connecting another network device to the fiber optic port using

a different cable. If the port is able to establish a link, then the

problem is with the cable or with the other network device.

Use the switch’s management software to verify that the port is

enabled.

If the remote network device is a managed device, use its

management firmware to determine whether its port is enabled.

x510 Series Installation Guide for Stand-alone Switches

Test the attenuation of both directions on the fiber optic cable with

a fiber optic tester to determine whether the optical signal is too

weak (sensitivity) or too strong (maximum input power).

Problem 5: Network performance between a twisted pair port on the

switch and a network device is slow.

Solution: There might be a duplex mode mismatch between the port and

the network device. This can occur when a twisted pair port using Auto-

Negotiation is connected to a remote device that has a fixed speed of 10

or 100 Mbps and a fixed duplex mode of full duplex. If this is the cause of

the problem, adjust the duplex mode of the port on the network device or

switch so that both ports are using the same duplex mode. You can use

either the LEDs or management software on the switch to determine the

duplex mode settings of the ports. The LEDs are described in Table 6 on

page 34.

Problem 6: The switch functions intermittently.

Solutions: Check the system hardware status through the management

software:

Use the SHOW SYSTEM ENVIRONMENT command in the

Privileged Exec mode to verify that the input voltage from the

power source to the switch is stable and within the approved

operating range. The unit will shutdown if the input voltage

fluctuates above or below the approved operating range.

Use the SHOW SYSTEM ENVIRONMENT command in the

Privileged Exec mode to verify that the fan is operating correctly.

Verify that the location of the switch allows for adequate airflow.

The unit will shutdown if it is in danger of overheating.

Problem 7: The Switch ID LED on the front of the switch is flashing the

letter “F.”

Solutions: One or more of the following problems has occurred:

A cooling fan has failed.

One of the power supplies has failed.

The input voltage on one or both of the power supplies is outside

the normal operating range.

The internal temperature of the switch has exceeded the normal

operating range and the switch may shut down.

Chapter 6: Troubleshooting

Problem 8: The AT-x510-28GPX or AT-x510-52GPX Switch is not

providing power to a PoE device.

Solutions: Try the following:

Review the PD’s documentation to confirm that the device

supports Mode A of the IEEE 802.3at standard. Mode A is one of

two modes that define the connector pins that deliver the power

from the port on the line card to the PD. In Mode A, the power is

carried on pins 1, 2, 3, and 6 on the RJ-45 port, the same pins that

carry the network traffic. The second mode, Mode B, defines pins

4, 5, 7, and 8 as the power carriers. The AT-x510-28GPX and AT-

x510-52GPX Switches do not support Mode B. Most powered

devices are designed to accept power by either mode, but some

legacy devices may only support one mode. This can be verified

by reviewing the device’s documentation or data sheet. Legacy

devices that only support Mode B will not work with the switches.

Check that the device’s power requirements do not exceed 30 W.

This can be verified by reviewing the device’s documentation or

data sheet.

Verify that you are using the appropriate category of twisted-pair

cable by referring to Table 3 on page 26.

Use the management software on the switch to determine whether

PoE is enabled on the port. The default setting for PoE is enabled.

Use the management software on the switch to determine whether

the PoE power setting for the port has been reduced to a value

below the power requirements of the device.

Try connecting the device to a different port on the switch.
