Replacing an ESM
Complete the following steps to replace the ESM that you removed before the
installation:
Attention: After you remove an ESM, wait 70 seconds before reseating or
replacing the ESM. Failure to do so may cause undesired events.
1. Slide one ESM into the empty slot in the expansion enclosure. Be sure that the
levers are pulled straight out as you slide the ESM in, as shown in Figure 23.
2. After you install the ESM into the bay, the ESM latch locks into place. Close the
levers until the pull-ring latches lock in place.
Attention: Make sure that the levers lock into place in the expansion
enclosure chassis.
3. Repeat step 1 and step 2 to replace the second ESM.
Replacing a power supply
Complete the following steps to replace the power supplies that you removed
before the installation:
1. Slide one power supply into the expansion enclosure. Be sure to replace the
power supplies so that the lever on each power supply opens toward the interior
of the expansion enclosure, as shown in Figure 24 on page 43.
Attention: Be sure that the lever is pulled straight out as you slide the power
supply into the expansion enclosure, as shown in Figure 24 on page 43.
