Checking Led Status - Allied Telesis Formula 8200 Installation Manual

Troubleshooting

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.
Additionally, each FX port has a set of LEDs to the right. For a closeup view of
the FX LEDs, see Figure 10.
Table 3 describes how these LEDs report on the switch and ports' status, and
what you need to do in case of a problem.

Description and Action Required
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.
