3. Installing the Q52
Site Requirements
INSTALLING THE Q52
This chapter describes the following:
•
Site Requirements on page 12
•
Unpacking the Q52 on page 13
•
Connecting the Q52 to a Network on page 13
Site Requirements
Prepare to install the Q52 in a clean, well-ventilated environment protected from
extremes of temperature, humidity, mechanical shock, or vibration. Provide enough
space at the front and back of the unit for cable connections.
Depending upon the specific options selected at time of ordering, the Q52 may be
powered from a 115 or 230 VAC outlet using the supplied external transformer through
a output cord to a barrel-style power connector, or over the Ethernet cable (Power Over
Ethernet - POE) from an Ethernet switch providing power as defined in the IEEE
standard 802.11af. If using the external AC transformer, prepare to install the Q52 within
four meters (13 feet) of a grounded 115 or 230 VAC outlet.
The Q52 must be installed within RF range of the local Zigbee wireless PAN, in order to
connect to the PAN and therefore bridge it over the TCP/IP network to the remote PAN.
The maximum distance from the Q52 to the nearest Zigbee PAN node will vary
depending upon the installation environment and capabilities of the other Zigbee
node(s).
The Q52 is an intentional radiator of Radio Frequency (RF) energy. In order to limit RF
exposure to personnel in the immediate area, the Q52 should be located and installed
such that a separation of at least 20 centimeters is maintained between the Q52’s antenna
and personnel in the vicinity of the device.

Dipswitch
Comments
OFF
OFF
Normal operation. With both dipswitches in the "OFF" position, the unit
will boot up using the settings in Flash rather than the default settings.
Dipswitch 2 is in the "OFF" position from the factory so that the new settings
that you store will be used.
ON
OFF
Factory default settings. With the dipswitches in this configuration, the
unit will boot up and all settings stored in Flash will be erased except the
Ethernet address and key value.
OFF
ON
Default IP (0.0.0.0). With the dipswitches in this configuration, the unit will
boot with factory default settings, but the stored settings in Flash remain
intact. This enables you to set an IP Address of your own. Setting dipswitch
2 to "ON" will not clear any settings that you have stored in Flash. It simply
boots the unit in a different state with the settings in Flash temporarily
ignored.
ON
ON
Factory bootloader mode. Do not use this mode except as directed by
Exegin technical support.
Use the RJ45 network connector, located on the side panel of the Q52 (see Figure 2), for
attaching to a 10/100Base-T (UTP) network. Plug a network cable into the network
connector. If installing a Q52 without the Power Over Ethernet (POE) option, insert the
three-prong power cable of the AC adapter into an AC outlet, and insert the barrel power
connectors into the POWER connector on the side panel of the Q52; this will power on
the device.

Gecko
Gecko is a Windows tool for discovering, monitoring, and configuring Exegin devices
on a TCP/IP network. The program is a Java stand alone program.
The Q52 can be configured on a TCP/IP network using Gecko. Two steps are involved:
1. Identify the Q52 on the network using TCP/IP as the underlying protocol
2. Configure the Q52 with its required TCP/IP settings (i.e. IP address and subnet
mask).
Additional settings like routing entries can also be configured allowing for
communications across subnets. Once Gecko is up and running, select Help Topics from
the help menu for more detailed information about Gecko.
The installation procedure for Gecko is described below; Using Gecko (Windows) on
page 23 describes how to use Gecko to configure your Q52.
Gecko
Environment
Requirements

TCP/IP Commands
Telnet
Telnet can be used to access a remote computer on a network. To use this command, you
must know the IP address of the Q52 ZigBee / 802.15.4 Bridge. You can start a Telnet
session on a UNIX- or Windows-based computer which is connected to the network, to
log in to the Q52 command line interface shell to alter and view settings.
Syntax:
telnet ipaddress
Example:
telnet 192.168.11.9
This will bring up the Q52 login prompt. Enter "root" for the User ID and press either
ENTER at the password prompt or, if a password has been set, then type it in and press
ENTER.
Ping
You can use the "ping" command to check that an assigned IP address (for example, the
IP address for the Q52) is active.
Syntax:
ping IPaddress
For example:
ping 192.168.11.9
The response will indicate whether the IP address is active or not.

5. Configuring the Q52 on Your Network
Required TCP/IP Settings
CONFIGURING THE Q52 ON YOUR NETWORK
This chapter describes how to configure the required and optional TCP/IP settings for the
Q52 on your network. The following steps are covered:
•
•
•
Required TCP/IP Settings:
•
Configuring an initial IP address for the Q52 on page 20
•
Configure the Q52 IP address and subnet mask on page 21
Optional TCP/IP Settings:
•
Communicating across routers on page 25
•
Using Host and Domain Names on page 26
Troubleshooting Tips on page 27.
Once the TCP/IP network port is configured on the Q52, additional configuration is
required to connect the Q52 to the local Zigbee Personal Area Network (PAN), and also
to bridge that local PAN to another remote PAN over TCP/IP. Please refer to Q52 Zigbee
PAN and Bridge Configuration on page 30 for details on Zigbee and bridge
configuration.
Required TCP/IP Settings
Configuring an initial IP address for the Q52
Since the Q52 has no physical user interface such as a display or keyboard, all operating
parameters must be configured by means of a TCP/IP network connection from a
separate computer. However, the Q52 must first be assigned an IP address in order to
function on a TCP/IP network. This raises the question of how to configure a Q52 when
it is first installed on the network fresh from the factory.
As delivered from the factory, the Q52 is configured to request an IP address from a
DHCP server when attached to a TCP/IP network. If a DHCP server exists on the
network, then the IP address assigned to the Q52 may be determined by querying the
DHCP server using its administration interface and locating the IP address of the desired
Q52 by matching its Ethernet MAC address. Please refer to the documentation for the
particular DHCP server used to determine how this may be done.
As an alternative, Exegin provides a utility program called Gecko which is capable of
locating any configured or unconfigured Q52 device attached to the TCP/IP subnet, and
assigning an initial IP address to it to facilitate subsequent configuration through a telnet
or HTTP connection. Please refer to Using Gecko (Windows) on page 23 for details on
how to do this.

An Important
Note
Once you have configured the unit using any of the above methods, the STAT LED will
flash once per second. This means the Q52 is configured and recognizable on the
network.
The STAT LED will flash when the IP Address is configured; it does not mean that
the unit is properly configured, only that an IP address has been saved.

Communicating across routers
Since Windows and UNIX environments depend on TCP/IP to communicate with the
Q52, crossing routers can be an issue.
After following one of the Q52 configuration methods described above, you will only be
able to communicate with the Zigbee bridge device from the same subnet. This means
that the Q52 will not be able to communicate across a router (i.e., to another subnet).
To allow the Q52 to communicate across a router, it is best to store a default
router/gateway within the Zigbee bridge device so that any packets destined for another
subnet are forwarded to this router automatically. The router (or series of routers) can
then ensure the packets arrive at their final destination on the other subnet.
You can configure a default router/gateway within the Q52 using either the Q52 HTML
forms or the TCP/IP telnet command.
Using HTML
forms
1. Follow the instructions for accessing the Network TCP/IP form (page 21).
2. Enter the address of the default gateway in the Default Gateway field.
3. Click on "Submit" when done.
4. Go to the Reboot page and click on "Reboot" to apply the new settings to your
system.

4. Logout of the Telnet session with "quit". Then reboot the Q52 by powering the
unit off and then on again.
Using Host and Domain Names
The Q52 allows entry of most IP addresses either in ’dotted quad’ form or as a symbolic
host names. Host names have the advantage that they are easier to remember and are not
tied to a specific IP address.
The translation from host name to IP address is performed by a Domain Name Server
(DNS). In order to use host names, the IP address for the DNS server as well as the
domain name suffix must be specified at configuration time.
Using HTML
forms
1. Follow the instructions for accessing the TCP/IP Settings form (page 21).
2. Enter the IP address of the Domain Name Server in the DNS Server Address field.
Note: this address must be entered in dotted quad format.

Troubleshooting Tips
Gecko error messages: Q52 will not talk on the network
Unable to assign temporary IP. The address is already in use.
•
Ensure that you have assigned an IP address that is not being use by another device.
Unable to assign temporary IP. The device is not responding. The network may be down,
or an invalid IP address has been used.
•
Ensure that the IP address that you used is valid for your network.
Q52 will not talk on the network
27
•
Have you assigned it a unique and valid IP address which corresponds with the
other IP addresses on your network? For example, are you sure no other device is
using this IP address, that the subnet mask is the same as other hosts on the
network, and that the unique IP address is part of the network specified by the
subnet mask specified?
•
Are you sure you are trying to talk to the Q52 from a host on the same subnet? The
Zigbee bridge device can only be seen locally unless you configured a routing entry
earlier on.
•
Is the STAT LED on the front of the Q52 flashing once per second or is it flashing
faster? A slower, once-a-second rate indicates that the Zigbee bridge device is in
fact configured with an IP address. A faster rate indicates that the Q52 is unaware of
the IP address and you may need to try the configuration process again.

5. Configuring the Q52 on Your Network
Troubleshooting Tips
•
Have you confirmed the network connection to the Q52 is working correctly?
Trying different network cables and locations will help narrow down the problem.
Cannot ping the Q52
There are a number of possible reasons for this:
•
Have you rebooted the Q52? Sometimes this will solve various communication
problems.
•
Is the network cable securely connected?
•
Have you checked your network connection to the Q52? Try it at a new location on
your network if possible or swap in another device.
•
Have you made an entry in your computer’s host table (/etc/hosts, host nis map, or
DNS name table) for the Q52?
•
Have you tried to ping with the IP address instead of the IP name? This will
eliminate any name-lookup issues and focus more on the communications between
the Q52 and your host.
•
Is it possible that a duplicate IP address has been assigned?
•
Did you use the correct netmask for your particular environment?
•
Has the Q52 been moved from another network? If so, it will likely need to be
reconfigured to integrate with its new location. This includes at minimum a new IP
address and netmask. Please see Resetting to Factory Defaults on page 99 for
possible configuration methods.
•
Is there a router between the Q52 and your host? If so, a default router or a static
route must be configured on the unit so the Q52 knows how to get its response back
to the originating host. Please see Communicating across routers on page 25.
•
Do you have a DHCP or BOOTP server running on your network? By default, the
Q52 comes with the DHCP and BOOTP request turned on so although you may
have stored a particular network configuration in the unit’s EEPROM, a DHCP or
BOOTP server may supply new network parameters upon bootup. To turn off
DHCP and BOOTP on the unit, please see Configure the Q52 IP address and
subnet mask on page 21.
If none of these help, try the following:
•
Reset the unit to default settings. Please see Resetting to Factory Defaults on page
99. Once the unit is in the default state, use one of the configuration options listed in
the "Q52 Configuration" above in the manual to reconfigure it.
Cannot Telnet to the Q52
If you are unable to ping the Q52 as well, please see Cannot ping the Q52 on page 28. If
it is telnet only that you are having problems with, these points should be considered:
•
28
Are you able to telnet to another host on your network or telnet from another host?
If not, look into your host’s TELNET configuration.
Q52 Installation and Configuration Guide © Exegin Technologies Limited, 2007
5. Configuring the Q52 on Your Network
Troubleshooting Tips
•
Have you tried rebooting the Q52?
•
Are the dipswitches in the "off" position?
•
Does the fourth octet of the Q52’s given IP address equal 0 or 255? Each of the four
octets in the IP address should be between 1 and 254.
HTML configuration forms will not display
•
Can you "ping" the Q52 from your Windows station? If not, please see Cannot
ping the Q52 on page 28.
•
Have you used the correct URL for the Q52’s home page? It should be:
http://Q52IPaddress

Figure 16—Bridge Settings Form
The Bridge Settings form allows specification of up to four remote Zigbee bridge
devices. The Q52 will attempt to connect to all specified bridge devices to bridge Zigbee
messages to and from the local PAN.
Remote Zigbee bridge devices are specified by IP address. At least one device should be
specified in order to bridge Zigbee message over the TCP/IP network.
IP addresses may be specified in dotted quad format, for example:
172.16.16.1
Alternatively, host names may be used to specify the IP address of each bridge device.
The Q52 requires access to a Domain Name Server (DNS) in order for host names to
work. Please refer to DNS Server Address on page 48 for more details on configuring the
DNS server address.
Hostname 1
At a minimum, the IP address one remote Zigbee bridge device should be entered into
the Hostname 1 field.
Default: Unconfigured (blank) IP address.
Hostname 2
Hostname 3
Hostname 4

Addressing
The Q52 may be set up to automatically request its TCP/IP parameters over the network
from a DHCP (Dynamic Host Configuration Protocol) server. To enable this feature,
click on the radio button labelled ’Obtain an IP address automatically’. When this feature
is enabled, the DHCP server will provide all TCP/IP configuration data; in this case,
none of the other fields on the TCP/IP Settings form need to be filled in.
If static addressing is desired, then click on the radio button labelled ’Use the following
IP address’. For static addressing, the IP address and Subnet mask are required to be
entered. All other parameters are optional, depending upon your installation
requirements.
Default: Unconfigured (blank) IP address and subnet mask; dynamic addressing
enabled.
Default
Gateway
If static addressing is used, and the Q52 will be required to communicate to a different
subnet, then the IP address of a default gateway is required in order to route traffic from
the Q52 to devices on remote subnets. You can leave this field blank if you are not
communicating across a router (from one network to another). In most other situations,
you simply enter your router's IP address in the Default Gateway field.
Default: Unconfigured (blank).

Q52 Command Line Interface Shell
Within the Q52, the command line interface shell is built into the firmware. It allows you
to manipulate objects such as destinations, models, and I/O ports and also provides some
monitoring and troubleshooting capabilities.
Command Line Interface access methods
Access the command line interface shell using these methods:
57
HTML Forms
When you configure a setting using the built-in HTML
configuration forms, shell commands are actually
executed remotely on the Q52.
Telnet Session
Opening a Telnet session with the Q52 allows you to
log into the device and access the command line
interface shell. (e.g. "telnet 192.168.11.9")
Q52 Installation and Configuration Guide © Exegin Technologies Limited, 2007
8. Reference Information
Q52 Command Line Interface Shell
Main command prefixes
The four main command prefixes within the command line interface shell are:
store
change settings stored in Flash. When the "store" prefix is used, the
Q52 must be rebooted to apply the changes to the system. Since
"store" affects Flash settings only, the Zigbee bridge device must reset
and read the new settings now in Flash.
set
change current/working settings in memory. When the "set" prefix is
used, a "save" command must be executed as well so that the new
settings are retained after power cycles. Since "set" only affects the
settings in memory, they will be lost after a power cycle unless they are
saved into Flash ROM.
list
view current/working settings in memory.
Command shell prompt
When the command shell is accessed through a Telnet session, a prompt is displayed
after login to indicate that it is ready to accept a command from the user. The Telnet
prompt is formatted ipaddress:userid> where IPaddress is the IP address of the Q52
and userid is the user ID of the currently logged-in user. For example,
192.168.11.32:root>
where 192.168.11.32 is the Q52’s IP address and the user is root.
Getting command help
The Q52’s command line interface shell provides several on-line help tools. These
include:
"?" Command
Typing "?" once logged in to the command line interface
shell will produce a full listing of all commands available.
Command Prefixes
Typing in the beginning of a command will produce an
error message showing the correct syntax. For example,
typing in "store tcpip" will produce a list of all
commands that start with this prefix.
Common command shell commands
The command line interface shell consists of more than 50 commands. Table 3 outlines
some of the more common commands. For a complete command reference, please refer

Table 7—Miscellaneous Commands
Command Syntax
Description
load [default]
Load the settings stored in Flash and use
them as the current or working settings. If
default is specified as well, factory
settings will be loaded. Use this after power
failure to restore settings saved in Flash.
netstat
Display current network status, including
TCP packet statistics and the current state of
each TCP and UDP socket in the system.
ping [-s] hostIPaddress
[datasize [packetnumber]]
"ping" another TCP/IP host, specified by
hostIPaddress, on the network. datasize is
the datagram packet size which defaults to
64 bytes if no size is included in the syntax
and packetnumber is the number of requests
to be sent.
To use a host or IP name instead of the
address, you must have set the DNS server
on the Q52. Use the command "set
sysinfo dns..." to do this.
For example:
ping 192.168.11.30
65
quit
Close the telnet command session.
restart
Perform a warm boot or hardware reset
simulating a power-on reset. This will
restore current settings to those stored in
Flash as the Flash settings will be read and
loaded into memory upon bootup.
save [default]
Save the current settings to Flash so they are
remembered after power cycles. Sysinfo,
destination, model, logpath, variable, user,
and I/O port settings will be saved. If
default is specified as well, factory
settings will be saved to Flash overwriting
any new settings you have configured.
Resetting the unit is not required.

8. Reference Information
Q52 Naming Scheme
Q52 Naming Scheme
The Q52 always follows this naming scheme:
exgnxxxxx
A default name of ‘exgn’ is followed by "xxxxx", the serial
number found on the bottom of the Zigbee bridge device. For
example: exgn00091
User Accounts and Permissions
When you log into the Q52, you either log in as a guest or as a root user. The commands
you will be able to utilize on the print server depend on which login name you use. By
default, there is one root user and one guest user; users can then be added to this with
either permission level.
Users with root permission can execute all commands: users with guest permission can
not do any configuration and can only execute commands that display settings on the
Q52. However, they can use ping and telnet as well.
Use list [default|stored] user on page 61 to look at current user definitions. Use set user
passwd username password on page 62 to see how the root user can change these
settings.
Resetting to Factory Defaults
Sometimes it is beneficial to return the Q52 to its factory default state. For example, if
you are having problems communicating with the Zigbee bridge device over the
network, you may want to put it back to a default state and reconfigure the network
settings.
To reset to factory defaults:
1. Move dipswitch 1 to the "off" position and dipswitch 2 to the "on" position as
described in Table 2, Q52 Dipswitch Settings, on page 15. This is the Factory
Settings mode
2. Reboot the unit by cycling the power off, then on.
You now have the Q52 booted into a default state, meaning its current/working settings
are those stored at the factory. All settings configured and stored in Flash are ignored
while the dipswitches are in the "Factory Settings" position.
At this point, you can use shell commands on the Q52 to configure certain settings. Here
are some common examples of steps taken when the device is in a default state:

Performing Firmware Upgrades
1. Forgotten Password
If you have forgotten a password set on the Q52, you can reset the user settings using
these commands:
set user from default
save
2. Restore All Settings in Flash to Defaults
Since this default state is temporary and you may want to make sure all settings
sitting in Flash are back to their factory default values, you will need to use these
commands:
save default
store tcpip from default
or set dipswitch 1=on and 2=off. See Table 2, Q52 Dipswitch Settings, on page 15.
3. Set dipswitches for normal operation.
Set dipswitch 1=off and 2=off. See Table 2, Q52 Dipswitch Settings, on page 15.
Performing Firmware Upgrades
Since the Q52’s firmware is stored in Flash ROM, upgrading is easy. Using a computer
with a web browser on a TCP/IP network, the Zigbee bridge device can be upgraded to
a newer firmware version without needing new hardware. Please refer to Firmware
Upgrade Form on page 52 for step-by-step instructions on how to load new firmware
into the Q52.

Ability to list settings but not configure them.
For each user, a password can be set. However, you would normally only set a password
for the root user to protect the Q52’s configuration. Guest users cannot alter the Zigbee
bridge device’s configuration in any way.
To configure the root password on your Q52, you will need to:
HTML Method
1. Load a Web browser on a network station that can communicate with the Zigbee
bridge device over TCP/IP.
2. Direct your Web browser to URL "http://Q52IPaddress/pswdConf.html"
(e.g. "http://192.168.11.9/pswdConf.html").
Note: If prompted for a "User ID" and password first, type in "root" for the ID and
press ENTER at the password prompt as there is no password by default.
3. Click within the "Old" field beside the "Root Password" heading and enter the
existing root password. By default, there is no root password; in this case, this step
can be skipped.
4. Within the "Root Password" section, click within the "New" field and enter the new
root password.
5. Within the "Root Password" section, click within the "Confirm" field and enter the
new root password again. Remember this the password is case sensitive.
6. Click on the "Submit" button when done.
7. Go to the Reboot page and click on "Reboot" to apply the new settings to your
system.
Manual (Telnet)
Method
1. Start a Telnet session with the Q52. Type:
telnet Q52IPaddress
2. Login to the Q52 through a command line shell session as a root user.
Note: If prompted for a "User ID" and password first, type in "root" for the ID and
press ENTER at the password prompt since there’s no password by default.
3. At the command shell prompt, follow this syntax:
set user passwd username password
For example, to set the root password to "mplex1" type:

set user passwd root mplex1
save
From this point on, anytime you log in to the Q52 as "root", you will need to specify
this password or else your login attempt will fail.
Note: This process can be repeated to clear or change the password. An alternate
method to clear the password has the following syntax:
set user from default
save
SNMP Security
SNMP does not include any formal type of security definition. However, security can be
accomplished using communities. A community is a string that is sent with every SNMP
request and is used to define a certain view of the MIB. By doing this, you can control
what parts of the MIB are accessed by an SNMP manager.
To access the Q52’s custom MIB, the public community string can be use to read any
variables that have access. To restrict write access, there is an additional security step,
involving defining a user named snmp on the Q52 with root privileges. The password
defined for this snmp user will then be used as the community string which allows write
access.
Note: If no snmp user is defined with root privileges, no write requests will be
accepted by the Q52.
Managing with SNMP
SNMP (Simple Network Management Protocol) is a protocol for internetwork
management services. This protocol provides a means for computers (or agents) to be
managed remotely by managers. The level of management depends on the manager and
agent. The level of management ranges from providing information such as statistics to
providing full management capabilities.
MIB (Management Information Base) files are a description of managed objects
available in an agent. MIB files provide the data for the manager so they can remotely
manage the agent. A MIB file is simply a formal description of the way an agent can be
accessed using SNMP and what functions can be managed.
The Q52 is a fully manageable SNMP agent that supports MIB-II, custom MIBs and
traps.

9. Extra Features/Additional Information
Managing with SNMP
MIB II Support
The Q52 is MIB II compliant allowing SNMP managers to monitor protocol, network,
and routing statistics.
Custom MIBs and Traps
The Q52 provides a custom MIB definition file which consists of 150 variables and three
traps. This MIB file allows you to monitor and configure the Zigbee bridge device
directly. In fact, the MIB file represents all of the possible configuration options such as
destination settings, network configurations, print queue status, loading of defaults, etc.
The Q52’s custom MIB definition file is included on the CD ROM supplied with the
Q52. This file can also be downloaded from the Exegin FTP site:
ftp.exegin.com
or can be accessed via the Exegin Web site:
http://www.exegin.com/
Custom MIB Variables
The variables found within the custom MIB definition file describe all information that
can be possibly be accessed on the Q52 by an SNMP manager. These variables can be
divided into two groups: system variables and product variables.
System
Variables
The first grouping of variables contain general information about the Zigbee bridge
device such as firmware version, serial number, etc. In addition to these, it includes a trap
table which defines what SNMP managers will receive by the traps generated on the
Q52. The trap table can have up to ten entries, but only the first entry is saved to flash
memory.
Product
Variables
The second grouping of variables contains information defining all of the remaining
functionality of the Zigbee bridge device. The product variables are divided into:
config group
Includes all configuration components such as models,
destinations, logpaths, and users.
status group
Includes all dynamic monitoring components such as print
queues, user logins, and RPRINTER configurations.
command group
Includes the save, load, and reset commands.
Note: These variables can have read, write, or read-write permissions. Along with these
permissions there are other elements that can limit the write access to these
variables. Please see SNMP Security on page 70 and Users and Passwords on
page 69 for more information.

Custom MIB Traps
A trap is an event generated by an agent to indicate a significant event to the manager.
By default, the Q52 will generate three traps:
coldstart
A generic trap generated every time the Q52 is powered on
or reset
authenticationFailure A generic trap generated whenever a disallowed access is
attempted
lpqIOStatusChanged The only custom trap. This trap is generated whenever the
I/O port’s status changes.
Compiling and Monitoring the Custom MIB
For read-only SNMP functionality, please follow the steps below:
1. Copy the Q52 MIB definition file (Q52mib.txt) from the CD ROM supplied with
the Q52. This file can also be downloaded from the Microplex FTP site
(ftp.exegin.com) or can be accessed via the Microplex Web site
(http://www.exegin.com/).
2. Compile this MIB description file to work with your SNMP manager.
3. Using your SNMP manager, view the particular MIB variables that you wish to
monitor.
Notes: If you are using SunNet Manager, you will need to download a special MIB file
(Q52mib.txt.SNM) from the Exegin FTP site. This file can also be accessed via
the Exegin Web site.
If you are using Castle Rock Computing’s SNMPc package, you will need to
rename the MIB variable UInteger32 to another name such as U32.
Writing to the Custom MIB
The following example explains how to use the custom MIB variables to set the Q52’s
parameters. For example, to turn on bb mode and onlcr on the Q52’s prn port, please
follow the steps below:
Note: This example assumes that the snmp password has been defined as custommib,
that the Q52’s ipname is spike, and that the SNMP manager is the Tricklets
package.
Issue the following configuration commands using the snmp user’s password as the
community string.
echo "m307IfPrnbbM[1.2]=2" | snmp-set spike custommib
echo "m307IfOnlcr[1.2]=2" | snmp-set spike custommib

Configuring the Q52 to Send Traps to an SNMP Manager
The Q52 continuously generates traps but unless the trap table is filled in, no SNMP
manager will receive this information. To set the Q52 to send traps to a particular SNMP
manager, please follow the steps below:
Note: This example assumes that the snmp password has been defined as custommib,
that the Q52’s ipname is spike, and that the SNMP manager is the Tricklets
package.
1. Set up an snmp user with root privileges on the Q52. Please see Compiling and
Monitoring the Custom MIB on page 72 for details.
2. Set the following Q52 trap variables using your SNMP manager. The actual syntax
of the commands will depend on the particular SNMP manager you are using.
echo "trapCommunity[1]=\"building-A\"" | snmp-set spike
custmmib
where building-A is the string that you want the Q52 to send with the trap
information. This community string has a 14 character maximum.
echo "trapDest[1]=192.168.11.11" | snmp-set spike
custommib
where 192.168.11.11 is the IP address of your SNMP manager.
Note: To disable the entry in the trap table, set the IP address to 0.0.0.0
The Q52 will now send trap information with the community string building-A to the
SNMP manager with the IP address 192.168.11.11. For more information on these trap
variables, please see their description in the custom MIB definition file.
Note: The trap table can hold up to ten entries but only the first entry is stored in Flash
memory. If you turn the unit off, you will lose the additional entries.

Watchdog halt
The watchdog timer is a hardware device that resets the system if not serviced regularly
by the CPU. It’s purpose is to prevent the CPU from entering an infinite loop because of
a hardware or firmware problem. After a watchdog interrupt, some diagnostic
information is saved for debugging and the device resumes operation in Auto-reset
Mode. The Q52 will auto-reset up to 16 times before entering non-operational Watchdog
Halt.
Spurious halt
Unsupported interrupts force the Q52 into this non-operational mode and typically
indicate a hardware problem.
