Caution
Excessive transmit signal levels at the receiver port can damage the card. Receiver input
specifications are P
min
= –31 dBm, P
max
= –7 dBm.
Step 5
Use an optical power meter to verify that receiver signal levels are within the specifications listed
(P
typ
= –29.0 dBm, P
min
= –31 dBm, P
max
= –7 dBm).

Step 6
Connect all the cables to the line card. If you are using an attenuator with the cable, see
Figure 6 on
page 7
.
Step 7
Tighten the top and bottom captive screws (
Figure 7 on page 16
).
Caution
Always tighten the captive screws on each Cisco uBR10-SRP- OC12SML DPT WAN line card.
These screws prevent accidental removal and provide proper grounding for electromagnetic
interference (EMI) shielding.
When fully inserted, the line card cycles through its power-on self-test. The Maintenance LED stays on
briefly (about 5 to 6 seconds) and then shuts off. If the Maintenance LED remains on or is flashing, see

.
For short distances (less than 15 km) an attenuator must be added to the cable configuration for the
Cisco BR10-SRP-OC12SML DPT WAN line card. See
Technical Specifications, page 22
.
Step 8
Configure the Cisco uBR10-SRP- OC12SML DPT WAN line card if necessary.
