Preparing for installation
There are important preparation requirements and handling procedures for use during product
installation.
Overview
CAUTION:
The Disk Enclosure - together will all its component parts - is too heavy to manually lift and install
into the rack cabinet. A minimum of three people and a suitable mechanical lift are required to
hoist the Disk Enclosure and install it into the rail kit assembly within the rack.
Make sure you wear an effective anti-static wrist or ankle strap and obey conventional ESD precautions
when touching modules and components. Do not touch mid-plane, motherboard, or module connectors.
See also the section, “ESD precautions” on page 55.
Unpacking the Disk Enclosure
Before unpacking the Disk Enclosure, familiarize yourself with the exploded view of packaging
components that pertain to your enclosure product. See also Chapter 9, “Enclosure packaging,” on page
75.
1. Examine the packaging for crushes, cuts, water damage, or any other evidence of mishandling during
transit.
If you suspect that damage has happened, photograph the package before opening, for possible future
reference. Retain original packaging materials for use with returns.
2. The unpacking sequence pertaining to 4U enclosures is shown in the following figures.
CAUTION: The Disk Enclosure does not ship with disk drive modules installed, but all rear
panel CRU modules are installed. This partially populated Disk Enclosure is quite heavy: 64 kg
(142 lb).
You can remove the Disk Enclosure from its shipping box using the standard belt-style lifting straps. If
available, you can remove the enclosure from its box using the optional lift handles instead of the
straps.
• Default method: remove the Disk Enclosure from its box using the straps. See the figure below, and
the CAUTION above and below the figure. The figure shows buckled belt-straps secured
longitudinally on the Disk Enclosure. Only the straps and plastic bag are shown. They are isolated
from the remainder of the packaging. As a visual aid for this unpacking task, see Chapter 9,
“Enclosure packaging,” on page 75 for more information about the packaging materials.
CAUTION: Verify that each belt strap is securely wrapped and buckled before performing the
lift.
