Installation
Installing the
BNC Module
This installation assumes that you have already installed the 2072
chassis.
To install the 2072 BNC Module, do the following steps:
1
Make sure the Asanté 2072 Hub’s power is turned on. Hav-
ing the power already turned on allows the LEDs on the
module to light when installed.
2
Observing the anti-static procedures, remove the module
from its anti-static packing.
❖
Note: Handle the module only by its edges. Do not touch
chips or connectors.
❖
❖
Warning:
Do not force the module into a slot. Forcing
the module into a slot can damage the backplane.
❖
3
Align the module to the inside edges of the card guides to
any available slot in the chassis. Gently slide the module in
until you can begin tightening the screws. See Figure 2.

4
Whether you use your screwdriver or hand-tighten the
module to the chassis, make sure you fasten both screws in
unison and apply the same amount of torque so that the
module attaches evenly to the chassis.
5
Make sure that one of the green segment LEDs lights. This
indicates that the module has been properly connected to
the backplane and is attached to one of the two segments.
(As a default, Segment 1 LED will light.)
