Installation and Safety Guide
Selecting a Site
Before you install the switch, review the following considerations about its
location.
■ For compatibility with Network Equipment Building System (NEBS), the
switch must be located in a network telecommunications facility.
■ The Rapier 48w switch requires an ambient temperature from 0ºC to 50ºC
(32ºF to 122ºF).
■ There should be adequate front-to-back airflow around the switch and its
vents.
■ The site should be dust-free and without moisture.
■ Humidity can be from 5% to 80% non-condensing.
■ You need a reliable and earthed (grounded) power supply source, preferably
dedicated and filtered.
■ Switch ports suitable for connection to intra-building or non-exposed
cabling are required.
■ Cabling must not be exposed to sources of electrical noise, such as radio
transmitters, broadband amplifiers, power lines, electric motors, and
fluorescent fixtures.
■ Related network devices can be connected to the switch but cannot exceed
maximum cable lengths specified in the Hardware Reference.
■ Ensure easy access to the switch’s power and cable connections.
■ You may need to remove cabinet doors to accommodate cords and cables.
■ When rack mounted, the switch must be located evenly to prevent uneven
mechanical loading of the rack.
