6-7 3000-A2-GA31-D0 July 1999
NOTE
To ensure proper alignment of
the circuit card(s) and rear
connector plate or connector
module, perform Step 7 only
during initial installation.
After that, remove or install
modular circuit cards from the
front of the carrier.
7. Return to the rear of the carrier and tighten either
the:
— Screw on the rear connector plate, or
— Two screws on the connector module.
Verify that the circuit card is firmly seated to ensure a
connection with the rear connector plate.
After installing the circuit card, do the following:
•
Connect the cables.
•
Install the ferrite chokes, if supplied; see Ferrite
Choke Installation on page 6-8.
•
Configure the unit as described in the device’s
documentation.
•
Perform verification testing as described in the
device’s documentation.
T1 CSU and T1 DSU/CSU
Circuit Card Installation
NOTE
Before installing a T1 CSU or
T1 DSU/CSU circuit card in a
carrier, you must first install a
T1 auxiliary backplane. Refer to
the
T1 Auxiliary Backplane
Installation section in Chapter 4.
After installing the T1 auxiliary backplane, you are
ready to install a T1 CSU or T1 DSU/CSU circuit card
(Figures 6-8 and 6-9).
