BorderNet™ 4000 SBC Installation and Deployment Guide

Installing the Rack Mount Kit
When mounting the BorderNet 4000 SBC, follow these requirements:
•
Elevated operating ambient: If installed in a closed or multi-unit 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) of
40
℃
.
•
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.
•
Mechanical loading: Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
•
Circuit overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Recommended power supply wiring for -48Vdc is minimum 12 AWG.
•
Reliable earthing: Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (for example, use of power strips). Only
minimum 12 AWG wire is suitable for use as earthing cable.
•
Rack Depth: The minimum rack depth is 600mm (24 inches). In addition, four-post
racks must have at least 20 inches between holes in order to bolt in the rail.
Before you install the BorderNet 4000 SBC, you must install a rack mount kit to support the
server in the rack.
The BorderNet 4000 SBC comes with a tool-less rail mount system and a conversion kit so
that the tool-less system can be used in a rack with either square holes or M5 round holes.
The round hole conversion kit uses M5 screws for mounting the adapter to the rack.
The rack mount kit is used only with a four-post rack and cannot be used with a two-post
rack. Both kits may contain extra hardware.
