If you are not familiar with these maintenance analysis procedures (MAPs), first read Using the maintenance analysis procedures.

You might have been sent here for one of the following reasons:

A problem occurred during the installation of a SAN Volume Controller 2145-4F2
The power-on switch failed to turn the node on
Another MAP sent you here

Perform the following steps:

Press the power-on switch on the SAN Volume Controller 2145-4F2 front panel.
Is the power-on indicator on the SAN Volume Controller 2145-4F2 front panel illuminated a solid green?
NO

Go to step 2.

YES

The power-on indicator on the front panel shows that the SAN Volume Controller 2145-4F2 has successfully powered on. Continue with MAP 5700: Repair verification to verify the correct operation.
Is the system board power LED indicator on the SAN Volume Controller 2145-4F2 rear panel flashing green?
NO

Go to step 3.

YES
The system board power LED indicator on the node rear panel shows that power is present at the power supply but the power-on switch failed to turn the node on.
- Replace the parts in the following sequence:
  - Power supply unit
  - Service controller
  - Front panel assembly
  - System board assembly
- Verify the repair by continuing with MAP 5700: Repair verification.
Is the system board power LED indicator on the SAN Volume Controller 2145-4F2 rear panel illuminated a solid green?
NO

Go to step 4.

YES
The System board power LED indicator on the node rear panel shows that the power-on switch on the SAN Volume Controller 2145-4F2 is on, but is not being displayed on the front panel power-on indicator.
- Replace the parts in the following sequence:
  - Service controller
  - Front panel assembly
  - System board assembly
- Verify the repair by continuing with MAP 5700: Repair verification.
Determine the type of uninterruptible power supply that you are using.
You can find out which uninterruptible power supply you are using by one of the following methods:
- Do a physical check of the uninterruptible power supply. The 2145 UPS is 2U high (3.5 in), while the 2145 UPS-1U is 1U high (1.75 in).
- Through the user interface, look at the node vital product data (VPD). See Viewing the vital product data for more information.
- Through the command-line interface, look at the node VPD by issuing the following command:
  svcinfo lsnodevpd nodeID
If your uninterruptible power supply is a 2145 UPS:

Go to step 5

If your uninterruptible power supply is a 2145 UPS-1U:

Go to step 9.
(from step 4)
Does the 2145 UPS powering this SAN Volume Controller 2145-4F2 node have its mode indicator a solid green?

NO

Refer to MAP 5200: 2145 UPS.

YES

Go to step 6.
(from step 5)
Does the 2145 UPS powering this SAN Volume Controller 2145-4F2 node have all of its circuit breakers on?
NO

Go to step 7.

YES
The input power to the SAN Volume Controller 2145-4F2 node is missing. Verify that the power cord assembly is correctly plugged in to the SAN Volume Controller 2145-4F2 and the 2145 UPS.
- Replace the parts in the following sequence:
  - Power supply assembly
  - Power cord assembly
  - Verify the repair by continuing with MAP 5700: Repair verification
(from step 6)
One of the circuit breakers on the 2145 UPS has tripped. Reset the tripped circuit breaker to on.

Does the circuit breakers on the 2145 UPS remain on?

NO

Go to step 8.

YES

Verify the repair by continuing with MAP 5700: Repair verification.
(from step 7)
One of the 2145 UPS's output loads caused a circuit breaker to trip. Remove each of up to eight SAN Volume Controller 2145-4F2 node power cables in turn and try to reset the circuit breakers to on.

Does the removal of any SAN Volume Controller 2145-4F2 node power cables enable the circuit breaker to remain on?
NO
2145 UPS output circuit breaker is faulty.
1. Replace the 2145 UPS assembly.
2. Go to MAP 5300: 2145 UPS repair verification.
YES
The input power current to the SAN Volume Controller 2145-4F2 node is too high.
1. Replace the parts in the following sequence
  1. Power supply assembly
  2. Power cord assembly
2. Verify the repair by continuing with MAP 5700: Repair verification.
(from step 4)
Does the 2145 UPS-1U that is powering this SAN Volume Controller 2145-4F2 node have its power-on and load segment 2 indicators a solid green, with service, on-battery, and overload indicators off?

NO

Refer to MAP 5250: 2145 UPS-1U repair verification.

YES

The input power to the SAN Volume Controller 2145-4F2 node is missing. Verify that the power cord assembly is correctly plugged in to the SAN Volume Controller 2145-4F2 and the 2145 UPS-1U.
