Hardware Description
Figure 7 shows the switch’s back panel with the AC connector.
Figure 7
Back Panel
Note
The AT-D8224XL switch has a DC power terminal block on the back
panel.
Port LEDs
Each switch port has two LEDs that indicate the following:
L/A LED - indicates a valid physical link with a device with packets
#
being received/transmitted and speed of transmission
D/C LED - indicates half- or full-duplex and collisions
#
Figure 8 shows the LEDs on the AT-8224XL switch. (Port LEDs
for an AT-8216FXL switch are located above each port. Port
LEDs for an AT-8288XL switch are located next to each port.)

AC Power
Connector
The RS232, DB-9 female connector on the front panel of the switch is
used to establish an out-of-band local management session with the
switch and the AT-S24 management session. Establishing a local session
requires a terminal or a personal computer with a terminal emulator
program. The terminal is connected to the RS-232 port with a straightthrough cable.
This button resets the switch. It is primarily used for diagnostics or
resetting the switch statistics stored by the management software,
Omega. You can also reset the switch using the Omega management
software, as explained in the
Guide
The switch’s system LEDs are Power, and Fault. They indicate the over-all
operating status of the switch.
More details about the LEDs, refer to Table 3,
Status
The switch has a single AC power supply socket on the back panel,
which has autoswitch AC inputs. The input voltage range is from
100-120/200-240 VAC, 4/2A, 50/60 Hz. The power cord acts as an ON/
OFF switch.

Hardware Description
Expansion Module Slots
The two expansion slots on the front panel of the switch can
accommodate a wide range of optional 10/100Base-TX, 100Base-FX,
1000Base-SX, 1000Base-LX, and 1000Base-T expansion modules. You
can use the modules to interconnect distant network devices, build a
high-speed backbone network, or attach additional nodes to the switch.
Note
For a list of the expansion modules supported by the switch and
the AT-S24 management software, contact your Allied Telesyn sales
representative or download a copy of the AT-S24 release notes
from the Allied Telesyn web site.
