IBM Partner Pavilion DS4100 manual Removing the CRUs, Removing a RAID controller

Removing the CRUs

Attention: This section describes how to remove the CRUs in order to minimize the weight of the DS4100 before you install it in the rack cabinet. However, if you have three or more people available to lift and install the DS4100 in a rack cabinet, you might not find it necessary to remove the CRUs before you install the DS4100. If this is the case, you can skip the CRU removal instructions provided in this section. Instead, continue with “Installing the DS4100 into a rack cabinet” on page 28, and then skip the CRU replacement instructions provided in “Replacing the DS4100 CRUs” on page 29.

Use the following procedures to remove the CRUs from the DS4100 before installation. Use these instructions after you have completed all applicable site, rack cabinet, and DS4100 preparations (as discussed in “Preparing for installation” on page 18) and installed the support rails (as discussed in “Installing the support rails” on page 22). Alternately, if necessary, you can use these instructions to lighten the DS4100 before removing it from the shipping box. The shipping box opens to provide access to the storage server CRUs.

The DS4100 comes with a rack-mounting hardware kit for installing it in a rack cabinet. It is easier to lift the DS4100 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 18. In the following procedure, you will remove the following CRUs from the storage server before you install it in the rack cabinet:

vRAID controllers

vPower supplies

vFans

vHot-swap hard disk drives

You do not need to remove the blank trays.

Statement 4:

CAUTION:

Use safe practices when lifting.

Attention: The storage server 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.
