3 Installing components
Overview
Component installation includes:
•
Rail kits
•
Controller and disk enclosures
•
Disk drives
NOTE:
If you have ordered the factory integrated product, skip this chapter and go to
“Turning
on power” (page 31)

Rack installation best practices
In addition to industry-standard recommendations, consider the following:
•
Locate the heaviest items, such as uninterruptible power supplies (UPS) and additional disk
enclosures near the bottom of the rack.
•
To make cabling easy, install the disk enclosures below the controller enclosure.
•
Install similar components next to each other in the rack. Because enclosures, switches, and
servers are of differing depths, if you have more than one of a device, mount those devices
adjacent to one another to accommodate working behind the rack.
WARNING!
To reduce the risk of personal injury or damage to the equipment, be sure that:
•
At least two people lift the storage system during removal or installation, if the weight exceeds
22.7 kg (50 lb). If the system is being loaded into the rack above chest level, a third person
MUST assist with aligning the system with the rails while the other two people support the
weight of the system.
•
The leveling jacks on the rack are extended to the floor.
•
The full weight of the rack rests on the leveling jacks.
•
The stabilizing feet are attached to the rack if it is a single-rack installation.
•
The racks are coupled together in multiple-rack installations.
•
Only one component in a rack is extended at a time. A rack may become unstable if more
than one component is extended.
•
To prevent damage and to ease insertion of the device into the rack, support the weight of
the device and keep it level when sliding it into the rack.
There are two typical rack configurations (

):
•
Multiproduct—maximizes space
•
Storage-centric—Makes future expansion easier
