current single-controller
■ A second cache module with the same memory configuration as installed in the current
cache module

Use the following steps to install a second controller, cache module and ECB:
CAUTION: After installing the EMU, check the PVA SCSI ID number on the master
enclosure to make sure it represents the correct enclosure number (ID 0). If the SCSI
ID number is not 0, reset it to ID 0 before starting the controller.
