Checking LED Status
The switch has system LEDs (Status and Power), located on the front panel,
that indicate the switch’s overall operational status. For the location of these
LEDs, see the encircled area in Figure 9.
Figure 9: Switch System LEDs
Additionally, each FX port has a set of LEDs to the right. For a closeup view of
the FX LEDs, see Figure 10.
Figure 10: FX Port LEDs
Table 3 describes how these LEDs report on the switch and ports’ status, and
what you need to do in case of a problem.

LED Description and Action Required
Status
Flashing green
means the switch’s system-wide operations are
normal.
Solid green means the switch software is locked up and you
probably cannot log in. Reboot the switch.
Flashing amber means the switch is completing a DRAM test
during a power on self test (POST); otherwise, there may be
problems. Reboot. If the LED state does not change, contact Allied
Telesyn’s Technical Support.
Solid amber
means the switch is still functioning, but with
problems. Try to determine the cause of the problem without
rebooting the switch. If all else fails, reboot.
