Servicing a DAE2
Figure 3-4 shows the status LEDs for the link control cards.

LCC Status LEDs
Table 3-3 describes the status LEDs visible from the rear of the disk
enclosure.
If the disk enclosure Fault light is on, examine the other status lights
to determine which FRU(s) is faulty. If a fault light on a FRU remains
on, you should replace that FRU as soon as possible.

Meaning
LCC Power
1 per LCC
Green
On when the LCC is powered up.
LCC Fault
1 per LCC
Amber
On when either the LCC or a Fibre Channel connection is faulty.
Also on during Power On Self Test (POST).
Primary Link Active
1 per LCC
Green
On when Primary connection is active.
Expansion Link Active 1 per LCC
Green
On when Expansion connection is active.
Power Supply Active
1 per supply
Green
On when the power supply is operating.
Power Supply Fault*
1 per supply
Amber
On when the power supply is faulty or is not receiving ac line voltage.
Flashing when either a multiple blower or ambient overtemperature
condition have shut off dc power to the system.
Blower Fault*
1 per cooling module
Amber
On when a single blower in the power supply is faulty.
* The DAE2 will continue running with a single power supply and three of its four blowers. Removing a power/cooling module constitutes a
multiple blower fault condition, and will power down the enclosure unless you replace a blower within two minutes.
