Cisco uBR10-SRP-OC12SML DPT WAN Line Card for the Cisco uBR10012 Router

About Removing and Replacing a Cisco uBR10-SRP-OC12SML DPT WAN Line Card

Caution Excessive transmit signal levels at the receiver port can damage the card. Receiver input specifications are Pmin= –31 dBm, Pmax = –7 dBm.

Step 5 Use an optical power meter to verify that receiver signal levels are within the specifications listed (Ptyp = –29.0 dBm, Pmin = –31 dBm, Pmax = –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.

For information about configuring the Cisco uBR10-SRP- OC12SML DPT WAN line card see Cisco uBR10-SRP-OC12SML-DPT WAN Line Card Feature Module at http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ubr10012/frus/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.
