QUICK START GUIDE 2 Feature Description The Cisco uBR-MC28 cable interface line card improves RF performance, supports spectrum management, increases system performance and supports online insertion and removal (OIR). The line card is available in three configurations: • Cisco uBR-MC28U—with an onboard upconverter and green end tabs Tighten the captive screws. Note The captive screws provide grounding for the electromagnetic interference (EMI) shielding. Figure 1 Warning Only trained and qualified personnel should be allowed to install, replace, or service this product; and should be properly grounded before handling this ESD-sensitive product. 88984 4 Installing the Card Step 1 The uBR-E-28U is an entry-level version of MC28U, for the uBR7225 chassis. The extra guide pins in the line card prevents it from being plugged into a different chassis. Make sure that you are grounded. 7 US 6 US 5 US 4 US 3 US 2 US 1 LE AB 88983 Step 1 Connect the downstream (DS) cables to the DS ports (DS0–DS1). RF DS port rings and end tabs are green (slate blue in the case of E-28U card). See Figure 5. Step 2 Connect the upstream cables to the US ports (US0–US7). 0-R DS F 1-R The cable interface line card insertion/removal method is the same for all Cisco uBR7200 series routers. Add RF attenuators as required to get the correct IF output. Insert the attenuator between the DS IF output cable and the upconverter. See Figure 3.

We strongly recommend that you reload the Cisco 7200 series router when replacing a cable interface line card with a card of a different type. 3 5 • The Cisco NPE-400 or Cisco NPE-G1 or Cisco NPE-G2 must be used with this card. US Installing the Card 3 Prerequisites 2 4 The Cisco uBR-MC28U/E-28U line card has an onboard upconverter. To cable the card: The Cisco uBR-MC28X line card does not have an onboard upconverter. The card may require up to 10 dB of attenuation due to a higher IF output power (higher then legacy Cisco line cards).

DS 0-R F LE AB Table 1 5 Removing the Card 6 Troubleshooting To prevent the alarms from activating, administratively shut down the card using the shutdown command in interface configuration mode before removing it from the chassis. 1. Make sure that the card is securely seated in the chassis. Step 1 Make sure that you are properly grounded. Step 2 Disconnect all the cables from the cable interface line card. Step 3 Unscrew the captive installation screws on the faceplate. Figure 4 Removing the Card from the Chassis If the captive screws do not tighten all the way, the card is not properly seated in the chassis or backplane. Carefully pull the card halfway out of the slot, reinsert it, and tighten the captive installation screws. Caution A partially seated line card can cause the router to reboot. 2. Are all enabled LEDs on? If yes, the system is operational. 88982 a. If the card has been enabled and configured for operations, the enabled LED remains on. 1-R F D DS F EN AB 0-R LE 7 US 6 5 US US 4 US 3 2 US US 1 US 0 US DS LEDs/Status LED/Status Description ENABLED—green ENABLED—off Card operating normally Card not enabled US—green US—off Upstream enabled Upstream not enabled DS—green DS—off Downstream enabled Downstream not enabled 7 Technical Specifications If no, check the following possibilities: uBR - MC28U Downstream LEDs DS0-DS1 b. If a port is enabled but its enabled LED is still off, check if the card has pulled away from the router. Reseat the card in its slot. (Do not have to turn off the system power to do this.} After the system reinitializes the interfaces, the enabled LED on the card should come on.
