Replacing SC180 Components
This section describes how to remove and install components of an SC180 expansion enclosure.
This document assumes that the customer has received the replacement component and is ready to
install it.
Safety Precautions
Always follow these safety precautions to avoid injury and damage to Storage Center equipment.
If equipment described in the document is used in a manner not specified by Dell, the protection
provided by the equipment may be impaired. For your safety and protection, observe the rules described
in the following sections.
NOTE: See the safety and regulatory information that shipped with each Storage Center
component. Warranty information may be included within this document or as a separate
document.
Installation Safety Precautions
Follow these safety precautions:
•
Dell recommends that only individuals with rack-mounting experience install an SC180 expansion
enclosure in a rack.
•
You need at least two people to lift the expansion enclosure chassis from the shipping box and three
people to install it in the rack. The empty chassis weighs approximately 62kg (137 lbs).
•
Make sure the expansion enclosure is fully grounded at all times to prevent damage from electrostatic
discharge.
•
When handling the expansion enclosure hardware, you should use an electrostatic wrist guard (not
included) or a similar form of protection.
The expansion enclosure chassis MUST be mounted in a rack; the following safety requirements must be
considered when doing so:
•
The rack construction must be capable of supporting the total weight of the installed chassis and the
design should incorporate stabilizing features suitable to prevent the rack tipping or being pushed
over during installation or in normal use.
•
When loading a rack with chassis, fill from the bottom up; empty from the top down.
•
To avoid danger of the rack toppling over, do not slide more than one chassis out of the rack at a
time.
•
The expansion enclosure must be operated with low-pressure rear exhaust installation [back pressure
created by rack doors and obstacles not to exceed 5 Pascals (0.5 mm water gauge)].
•
The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 35°C.
