Installing the Circuit Card in a Carrier
Read and follow all warning notices and instructions marked on the device or
included in this guide. See the
Important Safety Instructions
on page 12.
HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive components from damage
due to electrostatic discharge (ESD) during normal operation. When
performing installation procedures, however, take proper static control
precautions to prevent damage to equipment. If you are not sure of the
proper static control precautions, contact your nearest sales or service
representative.
To install a CSU or DSU/CSU circuit card in the 3000 Series Carrier, you must
first install an Auxiliary Backplane. For information about installing the
Auxiliary Backplane, refer to the
COMSPHERE 3000 Series Carrier
Installation Manual
.
Procedure
To install the circuit card:
1. Use a Phillips screwdriver to loosen the screw holding the circuit pack lock and
rotate the lock to the open position. Open the latch.

2. Hold the circuit card vertically at the front of the carrier, with the faceplate latch
in the open position.
3. Insert the card into the top and bottom card guides of one of the slots
numbered 1–16.
4. Slide the card into the slot. The ejector latch lifts up as it engages the metal
flange.
5. Press the latch up until it clicks into the locked position to secure the circuit
card in the carrier.
6. Rotate the circuit pack lock back into the closed position and tighten the screw.

Power-On Self-Test
After you install the CSU or DSU/CSU in the carrier and connect the carrier to a
power outlet, the CSU or DSU/CSU performs a power-on self-test to ensure that
the unit is in good working order. For information about the power-on self-test,
refer to the associated operator’s guide
.
To display the pass/fail status of the power-on test, use the procedure described in
Selecting a CSU or DSU/CSU
, and use the Self-Test Health command described
in the associated operator’s guide.
If the LEDs on the circuit card do not light during the self-test, there may be a
failure in the circuit card or in the carrier’s power supply. Install the circuit card in
another working carrier. If it works, or if a second circuit card in another slot in the
same carrier also does not light, check that the power cable is properly attached
and that the outlet is active. Refer to the
COMSPHERE 3000 Series Carrier
Installation Manual
.
Shared Diagnostic Control Panel
Use the LCD and keypad on the carrier’s Shared Diagnostic Control Panel (SDCP)
to select and access individual CSUs or DSU/CSUs within a carrier.
The SDCP includes one LCD, five LEDs, and eight function keys.
The LCD shows messages and menu tree choices. Messages include alarms,
command/test completion, and action in progress.
The OK, Alrm, and Test LEDs reflect the state of the selected CSU or DSU/CSU.
The Bckup and EC LEDs are not used for the 3100 Series products.
The 7-button keypad surrounding the LCD enables you to navigate through the
menu tree and select choices presented on the second line of the LCD. The eighth
key (Select) selects a unit, by slot address, to access through the SDCP. When
you select a particular CSU or DSU/CSU, the OK LED on that unit’s front panel
flashes on and off repetitively.
For more information about the SDCP, refer to the
COMSPHERE 3000 Series
Carrier Installation Manual.

Selecting a CSU or DSU/CSU
Procedure
To select a specific circuit card installed in the 3000 Series Carrier, perform the
following steps:
1. Press Select on the SDCP.
2. Enter a valid carrier and slot address. The green OK indicator on the selected
circuit card should flash. (It should be the only OK indicator flashing in the
cabinet.)
3. Press Select again. The display on the SDCP should show the last menu item
displayed, or in the case of a new installation, the top-level menu on the
selected circuit card.
Using the Communication Port on the Carrier
For specific information about enabling the COM port for carrier-mounted devices,
refer to Chapter 4 in the associated operator’s guide
.
NOTE:
If a Model 3161 DSU/CSU has the COM port enabled, Port 2 cannot be used
as a data port.
