Complete E2800 battery replacement
The steps to complete battery replacement depend on whether you have a duplex
configuration (two controllers) or a simplex configuration (one controller).
• For duplex configurations, see
Place controller online (duplex).
• For simplex configurations, see
Power up controller (simplex).
Place controller online (duplex)
Place the controller online to confirm the storage array is working correctly. Then, you can collect support data
and resume operations.
Perform this task only if your storage array has two controllers.
Steps
1. As the controller boots, check the controller LEDs and the seven-segment display.
The figure shows an example controller canister. Your controller might have a different
number and a different type of host ports.
When communication with the other controller is reestablished:
◦ The seven-segment display shows the repeating sequence OS, OL, blank to indicate that the
controller is offline.
◦ The amber Attention LED remains lit.
◦ The Host Link LEDs might be on, blinking, or off, depending on the host interface.
