Battery Canister LEDs

Figure 4 LEDs on a Battery Canister

Service Action Allowed LEDEach drive canister, power-fan canister, controller canister, and battery canister has a blue Service Action Allowed LED. The purpose of the Service Action Allowed LED is to help make sure that a canister is not removed before it is safe to do so.

ATTENTION Potential loss of data access – Never remove a controller canister, a power-fan canister, or a battery canister unless the Service Action Allowed LED is on or you are given specific instructions to do so by the storage management software.

If a canister fails and needs to be replaced, the amber Service Action Required LED on that canister comes on to indicate that service action is required. If no data availability dependencies, or other conditions that dictate the canister should not be removed, the blue Service Action Allowed LED comes on. The Service Action Allowed LED automatically comes on or comes off as conditions change. In most cases, the Service Action Allowed LED comes on steadily when the Service Action Required LED is on for the canister.

Table 4 LEDs on a Battery Canister


1 Battery Service Action Allowed

3 Battery Charging On – ready

Blinking – charging

Off



IMPORTANT If the Service Action Required LED is turned on but the Service Action Allowed LED is turned off for a particular canister, you might have to service another canister first. Check your storage management software to determine the action you should take.

The ability to remove a canister depends on the data availability dependencies of the controller tray. The Service Action Allowed LED does not come on if removing a canister jeopardizes data on the drive trays or current I/O activity. An example of limiting when you can remove a canister is when one controller canister has a Service Action Required LED on. You cannot remove the other controller canister (the Service Action Allowed LED does not come on), because doing so would jeopardize the data either on the drive trays or that is transitioning through the controllers.

Replacing a DriveUse the following procedure to replace a drive. You need antistatic protection and a replacement drive for this procedure.

ATTENTION Electrostatic discharge can damage sensitive components – Touching the array module or its components without using a proper ground might damage the equipment. To avoid damage, use proper antistatic protection when handling any components.

ATTENTION Speed requirement for a mixed configuration – In a configuration that uses various models of command modules, array modules, or drive modules, all modules on a fiber loop must operate at the same interface speed.

IMPORTANT For optimum performance, never insert a drive into an array module without first confirming the firmware level of the drive. Contact a Customer and Technical Support representative for information on supported firmware levels.

1 If needed, use the storage management software to create, save, and print a new storage array profile.

2 Did the Recovery Guru direct you to replace a failed drive?

■ Yes – Go to step 3.

■ No – Run the Recovery Guru to identify the failed drive, and go to step 3.

Replacing an SFP TransceiverUse the following procedure to replace a Small Form-factor Pluggable (SFP) transceiver on the array module. The SFP transceiver shown in this procedure might look different from those you are using, but the difference does not affect transceiver performance. You need antistatic protection and a replacement SFP transceiver for this procedure.



2 Did the Recovery Guru direct you to replace a failed SFP transceiver?


■ No – Run the Recovery Guru to identify the failed component, and go to step 3.




6 Unpack the new SFP transceiver. Make sure that it is the same type of transceiver you are replacing. If it is not, contact a Customer and Technical Support representative.

7 Check the Controller Service Action Required LEDs to locate the failed SFP transceiver. If a fault is detected, the amber Controller Service Action Required LED is on.



ATTENTION Potential degraded performance – To prevent degraded performance, do not twist, fold, pinch, or step on fiber-optic cables. Do not bend the fiber-optic cables tighter than a 5-cm (2-in.) radius.

ATTENTION Potential loss of data access – To prevent loss of access to data, remove only the SFP transceiver that has a failed status as shown in the storage management software.

8 Disconnect the fiber-optic interface cables from the SFP transceiver.

9 To remove the failed SFP transceiver from the controller, pull the lever on the SFP transceiver away from the controller and out of the port (Figure 10).
