DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:
Familiar with SCSI concepts in general

TIME ESTIMATE: 60 minutes
TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
- PROBLEM OVERVIEW

-The 3120 chassis FRU is ordered to replace a box that has been damaged or
whose midplane, backplane, or terminator module has been damaged.

WHAT ACTION DOES THE ENGINEER/ADMINISTRATOR NEED TO TAKE:

To make a fully functional array, you need to add the following parts from the
replaced array:

Drive Modules
Two Power Supply/Fan Modules

(To install the individual modules, use the REFERENCE INFORMATION section below)

To replace the chassis frame of an existing JBOD, perform the following steps:

*CAUTION* Connected hosts must be inactive during this replacement procedure.

1. Power off both power supply modules on the defective array.
2. Ensure all SCSI cables attached to the I/O module are labeled clearly.
3. Write down the defective array's cabling configuration.
4. Write down the SCSI ID switch setting, right or left.

Note - The IDs assigned for disks 1 through 4 depend on the switch settings on the array.
The right switch setting uses IDs 8, 9, 10, and 11. The left switch setting uses IDs 12,
13, 14, and 15.

5. Remove all SCSI cables attached to the I/O module.
6. Label each disk drive with its disk slot position in the array.
7. Remove the power supply modules and disk drives from the defective array.
8. Remove the defective chassis.
9. Obtain the replacement chassis.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE ENGINEER/CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

10. Re-install all previously removed modules in their original positions into the
replacement array.
11. Re-install all SCSI and power cables in their original positions.
12. Set the SCSI ID switch to right or left depending on your previous configuration.

Note – SCSI IDs are set based on the switch setting on the array when it is powered
on. If you change the switch setting, the SCSI IDs will change after you power off,
and then power on.

13. Power on both power supply modules on the replacement array.
14. Power on the host, if it was powered off.

15. Check the accessibility of the drives.
