Chapter 2 Preparing to Install the VG248
Rack-Mounting the System
Grounding the System
•
Do not defeat the ground conductor on an AC plug.
•
Connect AC-powered systems to grounded power outlets.
•
Connect the system to earth (ground).
Warning
There is the danger of explosion if the battery is replaced incorrectly.
Replace the battery only with the same or equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
Warning
Never defeat the ground conductor or operate the equipment in the absence
of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable
grounding is available.
Creating a Safe Environment
•
Keep tools and chassis components off the floor and away from foot traffic.
•
Clear the area of possible hazards, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
•
Keep the area around the chassis free from dust and foreign conductive
material (such as metal flakes from nearby construction activity).
Rack-Mounting the System
A rack-mount kit and cable guides come with the system. The kit is not suitable
for racks with obstructions (such as a power strip) that could impair access to
system components. Allow sufficient clearance around the rack for system
maintenance.
