6–20 SF7x Storage Enclosure FRU Replacement
6.1.3.2 Drive Module Replaced
Use this section only if you replaced the drive module. Follow each step
in the order presented and do not skip or miss any steps.
1. Set the MSCP switch to the disabled or up position (Figure 6–8).
2. Apply power to the disk ISE with the drive dc power switch.

NOTE
Following the replacement of either an HDA or a drive module,
a disk ISE performs a one-time calibration algorithm that
takes nominally 5 to 8 minutes, during which time the disk ISE
does not communicate with the host system. The calibration
sequence is complete when the Fault LED on the OCP stops
flashing and the Ready LED is on. Until this time, this disk
ISE is unavailable.
