power supply on the left side of the system is connected to a separate AC
source than the power supply on the right side of the system. This ensures
redundant power.
Note:
You do not need to ground EXN4000s; grounding is done through the
power cords.

Turn on power to the EXN4000 storage expansion units and wait for the disk
drives to spin up.
Setting the storage expansion unit shelf IDs
A unique shelf ID is required for each storage expansion unit within the entire
storage system.
About this task
A valid EXN4000 storage expansion unit shelf ID is 0 - 7.
If your storage system has SAS and FC storage expansion units, the storage
expansion unit shelf IDs do not need to be unique between the SAS and FC
expansion units. (FC expansion unit shelf IDs continue to be unique within each
FC loop. SAS expansion unit shelf IDs continue to be unique to all other SAS
expansion units in the storage system, including the N3220 or N3240 system's
internal SAS shelf ID.)
Visually verify that the shelf ID for each storage expansion unit is unique. If not,
set the shelf ID as follows. For additional details, see the
IBM System Storage
EXN4000 Storage Expansion Unit Hardware and Service Guide
.
Procedure
1.
Remove the front bezel if you have not already removed it.
2.
Press and hold the storage expansion unit shelf ID button
1
until the first
digit blinks.
3.
Press the button until the correct number is displayed.
4.
Repeat steps 2 and 3 for the second digit.
5.
Press and hold the button until the second number stops blinking.
Both numbers start blinking and the operator display panel fault LED
illuminates in about five seconds.
6.
Power-cycle the EXN4000 to make the new expansion unit shelf ID take effect.
