Interpreting the MAX indicator lights
Table 2-1 lists the lights on the front panel of the MAX and describes what each indicates.

Light
Description
Power
On (green) when the MAX power is on.
Fault
On (yellow) in one of two cases: either a hardware self-test
or a hardware failure.
When a hardware self-test is in progress, the light is on. If
any type of hardware failure occurs, the light flashes. If the
failure is isolated to an expansion card, the MAX might con-
tinue to function without the card.
Data
On (green) at power-up and whenever packets are detected
on the Ethernet interface.
Alarm
On (amber) at power-up. Thereafter, illumination indicates
detection of a low-power condition (MAX sends an SNMP
trap), WAN alarm, or a trunk out-of-service (for example,
during line loopback diagnostics). WAN alarms include Loss
of Sync, Red Alarm, Yellow Alarm, and All Ones (or AIS).
