Removing the CRUs
Attention: This section describes how to remove the CRUs in order to minimize
the weight of the EXP100 before you install it in the rack. However, if you have
three or more people available to lift and install the EXP100 in a rack, you might not
find it necessary to remove the CRUs before you install the EXP100. If this is the
case, you can skip the CRU removal instructions provided in this section. Instead,
continue with “Installing the EXP100 into a rack” on page 40, and then skip the
CRU replacement instructions provided in “Replacing the EXP100 CRUs” on page
41.
Use the following procedures to remove the CRUs from the EXP100 before
installation. Use these instructions after you have completed all applicable site,
rack, and EXP100 preparations (as discussed in “Preparing for installation” on page
30) and installed the support rails (as discussed in “Installing the support rails” on
page 34). Alternately, if necessary, you can use these instructions to lighten the
EXP100 before removing it from the shipping box. The shipping box opens to
provide access to the expansion enclosure CRUs.
The EXP100 comes with a rack-mounting hardware kit for installing it in a rack. It is
easier to lift the EXP100 and install it in a rack cabinet if you remove all the CRUs
first. You will need an antistatic wrist strap and a cart or level surface (to hold the
CRUs). Observe the precautions listed in “Handling static-sensitive devices” on
page 30.In the following procedure, you will remove the following CRUs from the
expansion enclosure before you install it in the rack:
v ESMs
v Power supplies
v Fans
v Hot-swap hard disk drives
You do not need to remove the blank trays.

CAUTION:
Use safe practices when lifting.
Attention: The expansion enclosure comes with a bezel that is attached to the
front of the unit. The bezel protects the light pipes that are located above the drive
trays. Leave the protective bezel in place until you are instructed to remove it.
Removing an ESM

Attention: After you remove an ESM, wait 70 seconds before reseating or
replacing the ESM. Failure to do so may cause undesired events.

rings and pull out on the levers to disconnect the ESM from the EXP100
midplane.
