Making Frame Relay Connections
To change the mode of an interface, reposition the jumper board for the port as follows:
Step 1 If the FRI is already in the node:
• Note its slot number.
• Loosen the captive mounting screws on both ends of the faceplate.
• Operate the card extractor levers and slide the card out.
Step 2 To change to DTE, move the jumper board one row of pins away from the FRI faceplate. (See
Figure 3-16.) For DTE mode, the jumper board should occupy rows 2, 3, 5, and 6.
To change to DCE, plug the jumper board into the connector receptacle pin rows closest to the FRI
faceplate. (See Figure 3-16.) The rows for DCE mode are 1, 2, 4, and 5.
Step 3 Insert the FRI card and gently slide it in all the way to the rear of the slot.
Note The FRI card should slide in easily into the slot. Investigate any binding. Do not use force.
Step 4 Insert and tighten the mounting screws.

Frame Relay Card Redundancy
Optional redundancy on a Frame Relay port is possible with a second FRM/FRI card set and a Y-cable
connection on each applicable port. The “Setting Up Frame Relay on an FRM” section on page 3-41
includes the step for configuring Y-cable redundancy. The card redundancy kit contains a second
FRM/FRI card set, Y-cables to interconnect the ports on the two back card, and four 200-ohm DCE or
DTE jumper cards if the back cards are either FRI-V.35s or FRI-X.21s. (The DCE or DTE port applies
