Feature Description

The Cisco uBR10-MC5X20S, U, and H cable interface line cards transmit and receive RF signals between the subscriber and the headend. Frequency ranges:

•Cisco uBR10-MC5X20S—5-42 MHz

•Cisco uBR10-MC5X20U—5-65 MHz

•Cisco uBR10-MC5X20H—5-65 MHz

The Cisco uBR10-MC5X20S/U/H cards have five downstream (DS) ports and twenty upstream (US) ports. The US ports are either fixed to a specific DS port or dynamically assigned to one or more DS ports, depending on the Cisco IOS software release.

Installing the Card

If you are replacing a Cisco uBR10-MC5X20S or U card with a Cisco uBR10-MC5X20U or H card, you must reconfigure the card.

---

Step 1 Make sure that you are grounded using an ESD-preventive wrist or ankle strap.

Step 2 Remove the protective sticker covering the DS ports.

Step 3 Verify that the ejector levers are open.

Step 4 Grasp the faceplate with one hand and place your other hand under the card.

Step 5 Align the upper and lower edges of the card with the upper and lower guides in the chassis.

Figure 2 Installing the Card

Step 6 Slide the card into the slot until you can feel it seat in the backplane connectors.

Step 7 Close both ejector levers to secure the card in the chassis. Engage and begin tightening the captive screws first by hand. Then, use either a T-10 Torx (included in the line card accessory kit) or a common flathead screwdriver to tighten the captive screws between 5 to 7 in-lbs.

---

Caution Only tighten the captive screws to a maximum of 7 in-lbs.

---

---

Tip Make sure that the captive screws are secure for proper electromagnetic interference (EMI) shielding.

Cabling the Card

Quad-shield coaxial cable bundles for the Cisco uBR10-MC5X20S/U/H cable interface line card can be purchased from Cisco, with the Universal Cable Holders (UCH) already connected to the coaxial cable bundles. Alternatively, custom-length quad-shield coaxial cable bundles can be purchased from third party vendors, with the UCH either connected to the cable bundles or provided as separate components.

Figure 3 shows the cable bundle for Cisco uBR10-MC5X20S/U/H cable interface line card to hybrid fiber-coaxial (HFC) plant that has 25 F connectors attached to one end and three UCH2 units attached to the other end. This cable is 9.84 feet (3 m) long and the part number is CAB-RFSW520QTIMF2.

---

Note Customers purchasing custom-length quad-shield coaxial cable bundles from third party vendors can purchase spare Universal Cable Holders and spare RF switch header blocks from Cisco. Please refer to Table 2 for the applicable Cisco part numbers.

---

Depending on your universal cable holder (UCH), refer to Cabling the Cisco uBR10-MC5X20S/U/H Interface Line Card with UCH1 Quick Start Guide or Cabling the Cisco uBR10-MC5X20S/U/H Interface Line Card with UCH2 Quick Start Guide.

Removing the Card

Shut down the card interface before removing the card from the chassis. Refer to "Shutting Down and Restarting the Interface" in the Cisco uBR10012 Software Configuration Guide.

If the maintenance LED is on, you can remove the card without affecting system operations.

Removing the UCH

For more information about the universal cable holders UCH1 and UCH2, refer to Cabling the Cisco uBR10-MC5X20S/U/H Interface Line Card with UCH1 Quick Start Guide or Cabling the Cisco uBR10-MC5X20S/U/H Interface Line Card with UCH2 Quick Start Guide.

---

Note The following instructions describe the disconnection process for the customized uBR cables and the maintenance of the Cisco preconfigured cable bundles.

---

---

Step 1 Make sure that you are grounded using an ESD-preventive wrist or ankle strap.

Step 2 Loosen the leadscrew (counterclockwise) on the UCH until it is completely disengaged from the faceplate.

Step 3 Pull the UCH straight away from the faceplate using the leadscrew.

---

Caution Do not use the cables to pull the UCH from the faceplate.

---

Figure 6 Loosening the Leadscrew

---

Removing the Card

---

Step 1 Using a T-10 TORX driver tool or flathead screwdriver, unscrew the top and bottom captive screws on the card.

Step 2 Simultaneously pivot both ejector levers away from each other to disengage the card from the backplane.

---

Caution The upconverter on the back side of the card may be hot.

---

Step 3 Slide the card out of the slot and place it on an antistatic surface with the component side facing up.

---

Tip Always install a blank cover in an empty slot to ensure proper cooling and airflow.

---

Troubleshooting

Check the following:

1. Verify that the LEDs light and go through the power on self test (POST) when the card is inserted in the chassis.

2. Verify that the captive screws and ejector levers are secure.

3. Verify that the POWER LED is on (green). If the LED off (not green):

a. Verify that there is power to the system.

b. Verify that the card is configured for the system.

Table 1 LED Descriptions 

LEDs	Description
POWER Green Off	Power on Power off
STATUS Green Blinking green Yellow	Booted, passed diagnostics Protect mode if redundant card In bootup mode
MAINT Off Yellow	No action required Okay to remove the card
US0-US19 Green Off	Configured, able to pass traffic Not enabled
DS0-DS4 Green Off	Configured, able to pass traffic Not enabled

4. If the card is cabled, check to see that the cables are securely attached and in the correct location.
