Replacing SC180 Expansion Enclosure
Components
This section describes how to remove and install components of the SC180 expansion enclosure.
This information assumes that you have received the replacement component and are ready to install it.
Safety Precautions
Always follow these safety precautions to avoid injury and damage to Storage Center equipment.
If equipment described in this section is used in a manner not specified by Dell, the protection provided
by the equipment could 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 is 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 the SC180 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 62 kg (137 lbs).
•
Make sure the expansion enclosure is always fully grounded to prevent damage from electrostatic
discharge.
•
When handling the expansion enclosure hardware, use an electrostatic wrist guard (not included) or a
similar form of protection.
The chassis must be mounted in a rack. The following safety requirements must be considered when the
chassis is being mounted:
•
The rack construction must be capable of supporting the total weight of the installed chassis. The
design should incorporate stabilizing features suitable to prevent the rack from 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, slide only 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]).
