Safety Information
WARNINGS:
•
Unload equipment from the cabinet before moving it.
•
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.
•
A safety risk exists 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 in a manner that will prevent the
equipment from accidentally sliding off the shelf. The following accessories may be
used to secure certain equipment on shelves: monitor tie-‐down kit (P/N 11725-‐701),
seismic equipment tie-‐down bracket (P/N 14061-‐719), or equipment tie-‐down
bracket (P/N 16356-‐719).
•
The cabinet can support many system configurations. The amount of force required
to tip or make the cabinet unstable differs with each. 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.
-
Slowly extend only one unit at a time. Extending multiple units may cause the
cabinet to tip over. Rapid deployment of the unit could cause the cabinet to tip.
•
For protection of the equipment and personnel, ground each cabinet individually to
the Telecommunications Equipment Bonding Conductor (TEBC) or Signal Reference
Structure (SRS).
•
Provide the minimum spacing between the accessories/components and the
housing that shall be maintained for safe operation of the equipment when installed
in accordance with the National Electric Code, ANSI/NFPA 70.
•
As appropriate, all wiring and equipment should be installed in accordance with
NFPA 70, “National Electrical Code,” and the applicable sections of ANSI C2,
“National Electrical Safety Code."
