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
About Troubleshooting the Cisco uBR10-SRP-OC12SML DPT WAN Line Card.
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.
Refer to the “Formatting Flash Memory Cards and Disks” section in the Cisco uBR10012 Universal
Broadband Router Hardware Installation Guide or the Cisco uBR10012 Universal Broadband Software
Configuration Guide, at http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/index.htm.

Note It is not necessary to configure the Cisco uBR10-SRP- OC12SML DPT WAN line card if you are
installing a replacement card in the identical slot. The system automatically downloads the necessary
configuration information from the PRE.
