Netfinity EXP300 Type 3531 9
You will need a flat-blade screwdriver and a Phillips-head screwdriver to install your
expansion unit. Each type of enclosure comes with general installation instructions
for installing optional devices.
Before you begin, review the following assumptions:
• If you are installing the expansion unit in a rack, you have already installed the
other components in the rack and moved the rack to its permanent operating
location.
• You have already installed and configured the host controllers and appropriate
host adapters.
• There are 68-pin VHDCI SCSI cables attached to the host controllers, ready for
final connection to the expansion unit.
• The installation site meets all area, environmental, power, and site requirements
for the expansion unit. Refer to the expansion unit requirements listed under
“Operating specifications” on page 5.
Preparing the expansion unit
This section explains how to remove the CRUs and set the interface options to prepare
the expansion unit for installation.
Removing CRUs
It is easier to lift the expansion unit and install it in a rack or tower enclosure if you
remove all CRUs (disk drives, power supplies, and ESMs) first. A fully loaded
expansion unit with 14 disk drives and two power supplies with built-in fans
installed weighs 36.1 kg (79.5 lb). The standard unit with two power supplies weighs
22.5 kg (49.5 lb). If you remove all the CRUs, you can reduce the overall weight.
Attention: If you have data stored on the drives, label the drives before you remove
them. Then, when you replace the drives, install each one in the same drive bay from
which you removed it.
See “Locations” on page 8 for information on removing the CRUs.
