Safety Information
WARNINGS (continued)
:
•
Unload equipment from the cabinet before moving it.
•
A standalone cabinet should be level, stable, and anchored to the floor. Two or
more cabinets can be bayed together (coupled) to enhance their stability. Each
cabinet should be anchored to the floor.
•
Before loading equipment in the cabinet, be sure to adjust and lock the leveling
feet to level the cabinet. Do not use casters to stabilize the cabinet; always
anchor the leveling feet or the cabinet frame to the floor.
•
Always load heavy equipment, such as a UPS, at the bottom of the cabinet first,
and add lighter equipment on higher levels.
•
There is a safety risk when equipment is mounted on a shelf installed more
than 30 inches (760 mm) above the floor in a cabinet without doors and/or side
panels. The equipment may accidentally slide or be accidentally pushed off the
shelf and fall on personnel. When equipment is mounted on a shelf in this
condition, securely fasten the equipment to the shelf or cabinet frame.
•
The cabinet can support many system configurations. The amount of force
required to tip or make the cabinet unstable differs with each configuration. Be
sure to read and follow your equipment manufacturer’s specific assembly,
installation, and safety instructions.
•
When servicing slide-mounted equipment such as servers:
-
Secure all equipment, other than the unit being serviced, in position to
prevent it from sliding out and destabilizing the cabinet.
-
Extend only one unit at a time. Extending multiple units may cause the
cabinet to tip over.
-
Extend the unit slowly. Rapid deployment of the unit could cause the
cabinet to tip over.
•
For protection of the equipment and personnel, ground each cabinet
individually to the Telecommunications Equipment Bonding Conductor (TEBC)
or Signal Reference Structure (SRS).
