Installing an EMU
CAUTION: Carefully align the EMU in the appropriate guide rails. Misalignment might
damage the backplane.
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.
1. Insert the EMU into its bay (see Figure 2–9, on page 2–17) and engage its retaining
levers.
2. Verify that the master enclosure PVA SCSI ID number represents ID 0. If it is not 0,
reset it to 0.
3. If there are no expansion enclosures, proceed to step 4.
If there are expansion enclosures, turn O
N all AC input boxes for each expansion
enclosure.
4. Turn O
N all AC input boxes for the master enclosure (see Figure 1-1, ).
5. If not already connected, connect a PC or terminal to the controller maintenance port.
6. Mount the logical units on the host. If using a Windows NT platform, restart the server.
7. Set the subsystem date and time using the following command in its entirety:
SET THIS_CONTROLLER TIME= dd-mmm-yyyy:hh:mm:ss
8. Disconnect the PC or terminal from the controller maintenance port.
