XFP ports The following XFPs are approved for use with 10GbE expansion modules
(XEM). The x900-24XT switch supports the XEM-1XP, and the AT-9924Ts
switch supports the AT-A60.
RJ-45 ports The 12-port RJ-45 expansion modules, models AT-A62 and XEM-12 T, feature
the following:
■ two rows of 6 RJ-45 ports
■ gigabit ports that support speeds of 10/100/1000Mbps
■ status LEDs
■ 32MBytes DDR-SDRAM for packet buffering shared among ports
■ 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 the x900 Series 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.
