Complete the following steps to remove and replace a failed ESM:
1. Check the storage-management software online help for instructions on ESM
failure-recovery procedures. Follow the steps provided before continuing to
step 2.
2. Label each cable to ensure that all cables are properly connected to the new
ESM.
3. Label the SFP modules when you remove them. You must install the SFP
modules in the same positions on the new ESM.
4. Remove the SFP modules and fibre channel cables from the failed ESM.
Attention: Be careful not to bend the fibre channel cables at a sharp angle
or pinch them with objects. This can decrease the performance or cause data
loss.
5. Be sure the Fault indicator LED is lit; then, push down on the ESM latch as
shown in Figure 55.
6. With the ESM latch in the down position, grasp the pull-rings and pull out on
the levers; then, remove the ESM.
Attention: After you remove an ESM, wait 70 seconds before replacing or
reseating the ESM. Failure to do so may cause undesired events.
7. Install the new ESM by sliding it into the empty slot. Be sure the levers are
pulled straight out as you slide the ESM into the storage expansion enclosure.
When you install the ESM into the bays, the ESM latch will lock into place.
8. Close the levers until the pull-ring latch locks in place. Make sure the levers
lock into place in the storage expansion enclosure chassis.
9. Reconnect the SFP modules and fibre channel cables to their original
locations.
10. Check the input and output bypass LEDs at both ends of the reconnected
cables. If the input and output bypass LEDs are lit, reconnect the cables and
SFP modules.
11. Check the Power and Fault indicator LEDs on the new ESM:
v
If the Power indicator LED is off, the ESM might not be inserted correctly.
v If the Fault indicator LED is lit, the Power indicator LED is off, or if any other
Fault indicator LEDs are lit, see Chapter 4, “Hardware maintenance,” on
page 77.
12. See your storage-management software online help for instructions for
enabling the ESM.
