Replacing an ESM
If you are replacing the only ESM in the EXP3500 storage enclosure, you must turn
off power to the storage enclosure before you replace the ESM. See “Turning off
the storage subsystem” on page 95 or see the documentation that comes with your
controller for additional information and instructions.
To replace an ESM, complete the following steps:
1. Read the safety information that begins on page “Safety” on page ix and “Best
practices guidelines” on page 8.
2. If the EXP3500 storage enclosure contains only one ESM, turn off the power to
the storage enclosure. See “Turning off the storage subsystem” on page 95 or
see the documentation that comes with your controller for additional
information and instructions.
3. Disconnect the cable from the ESM.
4. Open the two release levers. The ESM moves out of the bay approximately 0.6
cm (0.25 inch).
5. Slide the ESM out of the bay and set it aside.
6. Ensure that the release levers on the ESM are in the open position.
7. Slide the ESM into the bay until it stops.
8. Push the release levers to the closed position.
9. Connect the cable to the ESM.
10. Turn on the power. For more information, see “Turning on the storage
subsystem” on page 82.
11. Go to http://www.ibm.com/servers/storage/support/ to check for ESM code
updates. For more information, see the download instructions on page 1.
