Site Preparation
Dedicated primary branch circuit protection for each line feed supplied to the chassis.
-
It is recommended to use appropriately-sized circuit breakers that conform to local codes.

-
An ESD protection strap for use when installing or removing modules.
•
A PC or workstation running terminal emulation software (such as Microsoft HyperTerminal). This
•
will be used to communicate with the NPM management port during initial configuration.
Slotted screwdriver.
•
An Ethernet cable long enough to connect to the management workstation.
•
Personnel
Minimally, two people are required for lifting the chassis, and for positioning and securing the chassis
to the operations rack.
Site Space Requirements
This equipment is intended for use only in a Restricted Access Location. The Selenio VMG relies on the
building installation's safety measures for protection against short-circuit, over-current, and earth
(grounding) fault. Precaution must be taken to ensure these protective devices are in place prior to
installation, and that they are properly rated to protect the system.
Keep tools and chassis components off the floor and away from foot traffic.
•
Clear the area of possible hazards, such as wet floors, ungrounded power cables, and missing
•
safety grounds.
Keep the area around the chassis free from dust and foreign conductive material.
•
Note:

Rack Requirements
The operations rack for the VMG-14+ must comply with the requirements listed in this section.
Elevated Operating Ambient
•
If installed in a closed or multi-rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
Reduced Air Flow
•
Installation of the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised. Air flow on the Selenio VMG is from right (ingress
from the air filter) to left (from the front of the chassis).
Mechanical Loading
•
Mounting of the equipment in the rack should be in such a way as to ensure an even mechanical
load in the equipment rack.
