XFP ports The following XFP modules are approved for use with the AT-A60 10Gigabit
Ethernet expansion module for the AT-9900s.
RJ-45 ports The 12-port RJ-45 expansion module, model AT-A62, features the following:
■ two rows of 6 RJ-45 ports
■ gigabit ports that support speeds of 10/100/1000Mbps
■ status LEDs
■ two 16MByte DDR-SDRAM for packet buffering
■ cable fault detection and distance-to-fault diagnostics are available for RJ-
45 Ethernet ports (see the Test Facility chapter in the Software Reference for
the switch)
Test Facility
The test facility is a hardware test tool in AT-8900, AT-9900, and AT-9900s
software. Its primary function is to validate that there are no hardware
problems after installation of the switch or expansion options. You can also use
it as a troubleshooting tool, but it is just one of many such tools. You could
consider the test facility to be a specialised interface module, such as PPP or
Frame Relay, where the interfaces under test are dedicated to the test facility.
Before you use the test facility, disable configurations by using the
set configuration=none command, and restart or reboot the switch. For more
information about the test facility, see the Te s t Facility chapter in the Software
Reference.
Testing Ethernet LAN Ports
A crossover cable is required to run an Ethernet LAN test. How to make a
suitable cable is described in “Cables for RJ-45 Ethernet LAN Interfaces” on
page 30. To start the test, loop a four-pair crossover or straight-through cable
between two RJ-45 ports and enter the enable test interface=all command.
Interfaces connected by crossover cables are tested. If a test fails, contact your
authorised distributor or reseller.
To display test results, use the show test command. To display detailed output
with frame counts, use the show test count command. For example output
from these commands, see the Test Facility chapter in the Software Reference.
This chapter also contains information on how to test other interfaces.
