PRODUCT DESCRIPTION
The FlexDSX Rear Access Wire Wrap Chassis is an individual frame module for the
FlexDSX Front Cross-Connect System. Figure 1 shows the front of the chassis, with its wirewrap field for cross-connect termination and bantam jack field for test, patch, and monitor
access.
As shown, the chassis has a horizontal wire way for cross-connect wires and a hinged front
door with a label for recording cross-connect terminations. The chassis is 132.1 mm (5.2 in.)
high, 482.6 mm (19.0 inches) wide, and 149.9 mm (5.9 inches) deep.
The chassis requires a connection of 48 volts DC nominal at 1.0 amps maximum to provide
power for the cross-connect tracer lamps located on each circuit module. When a patch cord is
inserted in the MON OUT port on one of a cross-connect circuit, the tracer lamps on both
ends of the circuit blink off and on.
Figure 2 shows the chassis rear with its wire wrap terminals for Network Element (NE)
terminations. Each chassis provides test and patch access for 64 NE terminations.

UNPACKING AND INSPECTION
Unpack the FlexDSX chassis carefully, checking it for damage. If any item is damaged, file a
claim with the commercial carrier and consult ADC Customer Service. Keep the damaged
shipping containers for use in the claim. Even though no damage is evident, save the shipping
container for use if the equipment requires shipment at a future date.

CHASSIS INSTALLATION
Warning: FlexDSX products are designed to be located in a dedicated restricted access
communication equipment area. Never install equipment in a wet location or during a
lightning storm. When installing or modifying telephone lines, disconnect lines at the network
interface before working with uninsulated wires or terminals.
1. Determine where the chassis will be placed on the rack. Refer to Figure 4 for correct
chassis position.

2. Align the top and bottom mounting tabs on each side of the chassis with the slotted holes
in the vertical cable guide, as shown in Figure 5. (Cable rings do not have to be
removed.) Fasten the chassis to the bay using two #12-24 - 0.375 inch (9.5 mm) machine
screws on each side of the chassis.

4. Connect the 48V Terminal Block on the rear of the chassis to the respective circuit on
the fuse panel as indicated in Figure 6. Also, check to ensure that the dummy fuses have
been removed from the fuse panel and replaced with the correct type fuses (0.5 GMT).

CONNECTING NETWORK ELEMENT CABLES
1. Route the network element transmit and receive cables to the chassis following
instructions in ADCP-80-511, “FlexDSX System Planning and Application Guide.”
2. Prepare the individual wires to be terminated on the chassis by clipping off the ends
cleanly and stripping back the insulation about 4 cm (1.6 in.).
3. Terminate each transmit/receive (OUT/IN) circuit as follows:

Identify the chassis pins to be used for termination. Figure 7 shows the Tip Out
(TO), Ring Out (RO), Tip In (TI), and Ring In (RI) pins for one NE termination.
Label the twisted pair for the network element transmit signal and route the wires to
the upper pins identified TO and RO.
Label the twisted pair for the network element receive signal and route the wires to
the lower pins identified TI and RI.
Connect each individual wire to the pin. ADC recommends using five stripped turns
plus one turn with insulation on three corners of the wire wrap pin (see Figure 7).

INSTALLING CROSS-CONNECT JUMPERS
To cross-connect between circuit modules for two network elements, use the wire-wrap pins
on the bottom front of the chassis, identified in Figure 8. Between the two circuit modules,
cross-connect the IN and OUT wires, as shown in Figure 9.
