NET MGMT
Ethernet
Management
Port
The switch uses the NET MGMT port as a separate routed eth0 interface.
The interface is not part of the switching matrix of the Ethernet line cards,
but the switch can route traffic in or out of the port from the line cards.
Here are the guidelines to using the port:
The port should only be used for initial configuration and
maintenance access to the chassis.
The NET MGMT port has a standard 8-pin RJ-45 connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
The default setting for the port is Auto-Negotiation, which sets the
speed and duplex mode automatically. You may disable Auto-
Negotiation and configure the port manually.
The wiring configuration of the NET MGMT port is set
automatically with automatic MDIX detection. You may disable
automatic MDIX detection and set the wiring configuration
manually.
The port is referred to as eth0 in the management software.
The cable requirements for the port are listed in Table 6.

The Network Management (NET MGMT) port has one Status LED,
described in Table 7.
Console (RS-232)
Port You can use the Console Port to conduct local management sessions of
the switch. Local management sessions require a terminal or PC with a
terminal emulation program, and the management cable that comes with
the switch.
Local management sessions are not conducted over a network.
Consequently, the switch does not need an Internet Protocol (IP) address
for this type of management.
Because the switch does not come with a default IP address, your initial
management session must be a local management session. For
instructions on how to start a local mana gement session, refer to “Startin g
a Local Management Session” on page 114 or the Software Reference for
SwitchBlade x908 Gen2 Switch.

You can install either one or two power supplies in the chassis. A
single power supply can power a fully equipped chassis. Installing
two power supplies adds power redundancy. If a power supply fails
or loses power, the second power supply continues to power the
system, thus preventing a disruption to network operations.
The power supplies are installed in the PSU A and PSU B slots in
the front panel of the chassis. If you are installing only one power
supply, Allied Telesis recommends installing it in PSU A slot
because that slot does not come with a blank slot cover.
The switch does not come with power supplies. They must be
purchased separately.
The power supplies are field-replaceable and hot-swappable. You
do not have to power off the switch to replace them.
Caution
The AT-SBxPWRSYS2 and AT-SBxPWRSYS1-80 Power Supplies
are not compatible with each other. Do not install both types of
power supplies in the same chassis.
Chapter 1: Overview
34
AT-FAN08 Units
The cooling unit for the chassis is the AT-FAN08 Fan module. Refer to
Figure 7.
Figure 7. AT-FAN08 Module
The chassis comes with two pre-installed fan modules in FAN A and FAN
B slots on the rear panel. The air flow is from the front to the back of the
chassis, with the fans drawing air out of the device.
The fan module has two fans. The switch automatically adjusts the speeds
of the fans, depending on its internal temperature.
The AT-FAN08 module is field-replaceable and hot-swappable. You do
not have to power off the switch to replace a fan module.

Choosing a Site for the Chassis
Observe these requirements when planning the installation of the chassis.
The AT-SBx908 Gen2 Chassis should be installed in a standard
19-inch equipment rack. It should n ot be installed on a table, d esk,
or wall.
Check that the equipment rack is safely secured so that it will not
tip over. Devices should be installed in the rack starting at the
bottom, with the heavier devices near the bottom of the rack.
The power outlet should be located near the chassis 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 is from front to back, with the fans on the back
panel drawing the air out of the unit.)
The site should not expose the chassis 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.
Twisted pair cabling should not be exposed to sources of electrical
noise, such as radio transmitters, broadband amplifiers, power
lines, electric motors, or fluorescent fixtures.
Switch ports are suitable for intra-building connections, or where
non-exposed cabling is required.
Do not install the chassis in a wiring or utility box because it might
overheat and fail from inadequate airflow.

Cabling the 1Gbps or 10Gbps Ports on the AT-XEM2-12XT Line Card
Here are the guidelines to cabling the 1Gbps/10Gbps twisted pair ports on
the AT-XEM2-12XT Line Card:
The cable specifications for the ports are listed in Table 2 on
page 23.
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to Auto-Negotiation, the default setting, to
operate at 1Gbps.
The ports support full-duplex only.
Do not attach cables to ports of static or LACP port trunks until
after configuring the trunks on the switch. Otherwise, the ports will
form network loops that can adversely a ffect network performance.
AT-SBx908 Gen2 Switch Installation Guide

Guidelines to Handling SFP, SFP+, and QSFP+ Transceivers
Please review the following guidelines before installing SFP, SFP+, or
QSFP+ transceivers in the line cards:
The transceivers are hot-swappable. You can install them while the
switch is powered on.
For a list of supported transceivers, refer to the product data sheet
on the Allied Telesis web site.
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 its 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. Whe n you do remove the plug, keep it for
future use.
Unnecessary removal and insertion of a transceiver can lead to
premature failure.
Caution
Transceivers 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
devices. E92

Troubleshooting
This chapter contains suggestions on how to troubleshoot problems with
the switch.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: All of the port LEDs and the Switch ID LED are off, and the
fans are not operating.
Solutions: The unit is not receiving power. If the switch has AT-
SBxPWRSYS2 AC Power Supplies, try the following:
Verify that the power cord is securely connected to the power
source and 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 wit hin th e requ ired
levels for your region. The power requirements for the switch are
listed in “Power Specifications” on page 163.
If the switch has AT-SBxPWRSYS1-80 Power Supplies, examine the
LEDs on the power supplies. The power supplies are operating normally
when the DC IN and DC OUT LEDs are solid green and the Fault LED is
off. Possible fault conditions and their solutions are described here:
Fault Condition 1: If the DC IN LED is o ff, the power supply is not receiving
power, has overheated and been disabled, or has failed and needs to be
replaced. Try the following:
Verify that the On/Off switch on the power supply is in the On
position.
Verify that the DC circuit breaker is on.
Verify that the positive and negative power wires are correctly and
securely connected to the terminal block on the power supply and
circuit breaker.
Chapter 7: Troubleshooting
156
Verify that the DC circuit break has power by attaching another
device to it.
Verify that the power from the DC circuit break is within the
required levels of the power supply. Refer to “Power
Specifications” on page 349.
If the chassis is still operating, use the SHOW SYSTEM
ENVIRONMENT command in the User Exec or Privileged Exec
mode to determine if the power supply has overheated and
shutdown. The Status column in the display provides the states of
the chassis modules. Components that have an “Ok” status are
operating normally.
Fault Condition 2: If the DC IN LED is solid green but the DC OUT LED is
off, the power unit is generating insufficient DC power. Re place the po wer
supply.
Fault Condition 3: If the Fault L ED is solid amber, try the solut ions in Fault
Condition 1. If they do not resolve the problem, replace the power supply.
Note
The power supply is hot swappable. If the chassis has two power
supplies and one of them fails, you do not have to power off the
operational power supply to replace the failed unit.
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 1GBase/10GBase twisted pair port on the AT-XEM2-12XT
Ethernet Line Card 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 network device connected to the twisted pair port is
powered on and is operating properly.
Verify that the network device supports 1Gbps or 10Gbps
operation. The AT-XEM2-12XT Card does not support 1Mbps or
10Mbps devices.
Try connecting another net work 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.
AT-x908 Gen2 Swich Installation Guide
157
Verify that the twisted pair cable do es not excee d 100 mete rs (328
feet).
Verify that you are using the appropriate category of twisted pair
cable. Cable requirements are listed in Table 2 on page 23.
Verify that the port is connected to the correct twisted pair cable.
Note
A 1GBase/10GBase connection may require five to ten seconds to
establish a link.
Problem 4: The LINK/ACT LED for an SFP, SFP+, or QSFP+ 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 t he port on
the transceiver and to the port on the remote network device.
Check that the transceiver is fully inserted in the slot.
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.
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.
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: 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 shut down if the input voltage
Chapter 7: Troubleshooting
158
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 shut down if it is overheating.
Problem 6: 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.
The internal temperature of the switch has exceeded the normal
operating range and the switch might have to shut down.
