AT-9924T switch Key features are:
■ Autonegotiating, multi-layer gigabit switch
■ 24 x 10BASE-T/100BASE-TX/1000BASE-T ports (RJ-45 connectors)
■ 4 x SFP ports (see “Network Ports” on page 20 for speeds)
■ Hot-swappable, load sharing PSUs
AT-9924T front panel
There can be 24 ports operational at one time. The RJ-45 ports 1 to 4 use the
same physical interface as the SFP ports 1 to 4. When an SFP is inserted into an
SFP port, the corresponding RJ-45 port is disabled. For example, if an SFP is
inserted in SFP port 1, then RJ-45 port 1 is disabled. When the SFP is removed
from port 1, the RJ-45 port 1 is again operational. All other RJ-45 ports function
normally.

Green The PSU is installed and supplying power to the switch. The voltage
output is within specification.
Red One of the following:
• The PSU is installed in the switch, and a fan has failed or the PSU
has exceeded its recommended temperature threshold.
• A FOM is installed in the switch and a fan has failed. Note that
the SwitchBlade x908 switch does not support FOMs.
• The bay is empty. Applies to AT-8948, AT-9924Ts, x900 -24XT,
x900-24XT-N, and x900-24XS switches since they require a
FOM when only one PSU is installed.
• Dual PSUs are installed, but the PSU is not receiving power.
• The standby switch has been turned off.

The following flash sequences indicate a hardware-related fault.
After sequences of two or more flashes, the LED stops briefly , then
repeats the sequence. If multiple faults occur, the LED flashes each
sequence in turn, stops briefly, then repeats the sequences.
1 Flash One or more heatsink fans has failed or is operating below the
recommended speed.

not installed, or the fans are operating below the recommended
speed.

Management Ports
The following management ports let you configure, monitor, and upgrade the
switch:
■ RS-232 Terminal Port
■ Out-of-Band Ethernet Management Port
RS-232 Terminal Port
The RS-232 ASYN0/CONSOLE port is standard for the x900 series switches
and SwitchBlade
configuration. This port allows the software on the switch to be accessed from a
terminal or a PC running terminal emulation software.
The ASYN0/CONSOLE port has an RJ-45 socket with an industry recognised
pinout. This requires using a straight-through RJ-45 cable with an RJ-45 DB9
connector when the switch is connected to a terminal or PC. The socket is
wired as a DTE and the pin layout is shown in the following table. Pins a re

Out-of-Band Ethernet Management Port
The out-of-band 10/100/1000 Mbps Ethernet port (Eth0) is dedicated to
management traffic on the following switches:
■ AT-9924Ts
■ x900-12XT/S
■ x900-24X series
■ SwitchBlade x908
C613-03092-00 REV J
Use the management port for initial configuration and on-going management
tasks. For remote access, use the default IP address, 192.168.242.242. This port
is reserved for management only; the switch does not transmit frames between
this port and switch ports.
On the SwitchBlade x908, the management port can also be used to create a
stack resiliency link when the switch is part of a virtual chassi s stack. For more
information about resiliency links, see the Stacking Introduction chapter of the
AlliedWare
Plus™ Operating System Software Reference.
