T1 AND E1 REMOTE ACCESS CONCENTRATORS

3.4 Placement
Installation sites must be within reach of the network cabling and must meet the following requirements:
• A properly grounded AC power receptacle must be within 7 feet (2.1 m) of the location.
• Temperatures at the installation site must remain between 32 and 104˚F (0 and 40˚C), with fluctuations of
less than 18˚F (10˚C) per hour.
• If you are placing the Concentrator on a shelf, the shelf must be able to firmly support 13 lb. (5.9 kg) of
static weight for each Concentrator on the shelf.
• If you are placing the Concentrator in a rack, there must be at least two inches (5 cm) of clearance on each
side of and behind the Concentrator for adequate ventilation.
3.5 Rackmounting (Optional)
CAUTION!
Before installing the Concentrator in a rack, make sure that the rack can hold the
Concentrator securely without toppling, warping, breaking, etc. Otherwise, personal
injury and equipment damage might result.
Do
not
use screws other than those included with the Concentrator’s Rackmount
Kit to attach the Kit’s rackmount brackets to the Concentrator’s chassis. Wrong-sized
screws can cause electrical shorts and can physically damage the Concentrator.
To mount a Remote Access Concentrator in a 19" rack, you’ll need to attach the brackets from its included
rackmount kit to the Concentrator, then attach the bracketed assembly to your rack. You’ll need both a flathead
and a Phillips screwdriver to do this.
Take these steps:
1. Decide which way you want the Concentrator to face. The standard installation is with the front of the
Concentrator facing the front of the rack; the rest of the directions in this section assume that orientation.
But you can install the Concentrator with its rear panel facing the front of the rack instead. If you do so,
you’ll have to install the brackets upside down, so that they screw onto the
bottom
edge of the
Concentrator’s side. You’ll also have to substitute “rear of the Concentrator” for “front of the
Concentrator” in the following steps.
