This quick start guide describes how to install a Cisco uMG9850 QAM Module in a Cisco Catalyst 4500 series switch.
 |
Caution For safety information you need to know before installing the Cisco uMG9850, see the Cisco Catalyst 4500 Series Regulatory Compliance and Safety Information document that accompanied your Cisco Catalyst 4500 series switch. That document provides translations for each of the warnings found in this guide. |
The Cisco uMG9850 QAM Module (see Figure 1) is a switching module for Cisco Catalyst 4500 series switches that allows cable operators to deliver Video-on-Demand (VoD) services to their subscribers. The module receives multiple single-program transport stream (SPTS) MPEG-2 digital video streams over IP. Modulated and upconverted RF signals are then delivered to subscribers' digital set-top boxes.
The Cisco uMG9850 QAM Module provides 12 downstream dual-QAM RF ports, through three groups of four F-connectors. Other ports on the module include a 10/100/1000 Gigabit Ethernet (GE) port, an SFP-GE port, and an ASI monitor port. Figure 2 and Table 1 identify the connectors and LEDs on the front panel of the Cisco uMG9850.
To operate properly with Cisco uMG9850 QAM modules, the Cisco Catalyst 4500 series switch must be equipped with specific hardware and software options. Before installing the Cisco uMG950, review the "Cisco Catalyst 4500 Series Configuration Options" section in the Cisco uMG9820 QAM Module Release Notes to verify that your switch is configured with these options.
The following equipment and tools are required to install the Cisco uMG9850:
 |
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034 |
|
Caution To prevent electrostatic discharge (ESD) damage, handle modules by the carrier edges only. |
To install the Cisco uMG9850 in a Cisco Catalyst 4500 series switch, perform these steps:
Step 2 Choose a slot for the module (see Table 2). Ensure that there is enough clearance for any interface equipment that you connect to the module ports.
Step 3 Loosen the captive installation screws that secure the module filler plate (or the existing module) to the desired slot.
Step 4 Remove the faceplate (or the existing module).
 |
Note If you are removing an existing module, see Removing a Cisco uMG9850. |
Step 5 To install the module, hold the module front panel with one hand, and place your other hand under the carrier to support the module, as shown in Figure 3. Do not touch the printed circuit board or connector pins.
Step 6 Align the edges of the module printed circuit board with the slot card guides on the sides of the switch chassis as shown in Figure 3.
Step 7 Move the two module ejector levers out and away from the faceplate.
Step 8 Carefully slide the module into the slot until the notches on both ejector levers engage the chassis sides.
Step 9 Using the thumb and forefinger of each hand, simultaneously move both ejector levers, as shown in Figure 4, to fully seat the module in the backplane connector.
|
Caution Always use the ejector levers when installing or removing modules. A module that is only partially seated in the backplane does not function properly. |
|
Note If you perform a hot swap, the console displays the message "Module n has been inserted." This message also appears if you are connected to the Cisco Catalyst switch through a Telnet session. |
Step 10 Use a screwdriver to tighten the captive installation screws on the faceplate.
Step 11 Attach network interface cables or other devices to the interface ports. See Cabling a Cisco uMG9850.
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001 |
Connect the QAM, ASI monitor, and Ethernet cables to the module as shown in Figure 5.
|
Note F-connector cables connected to the Cisco uMG9850 should meet the "quarter-quarter" cable preparation convention (1/4-inch braid exposure and 1/4-inch center conductor exposure). Adherence to this convention prevents excessive signal loss if the center conductor is too short, and avoids mating interface damage if the center conductor is too long. (Tools such as the Cable Prep CPT-6590 are available for this purpose.) |
Cables connect to the SFP-GE port using a fiber-optic Small Form-Factor Pluggable (SFP) module.
|
Caution Use only SFP modules supplied by Cisco, which have Class 1 Laser Product and FDA CFR certifications. Class 1 Laser Product modules are safe for the eyes when operated within the limits of the device specification. For more information, see the specification of the SFP module that you are installing. |
To insert an SFP module into the GE port:
Step 2 Find the transmit and receive markings that identify the top side of the SFP module.
Step 3 See Figure 6. Aligning the back (receive) end of the module in front of the port labeled "1000-X," insert the module into the port until you feel the connector snap into place.
Step 4 Remove the dust plugs from the SFP module and store them for later use.
Step 5 Insert fiber-optic cable into the front (transmit) end of the SFP module.
|
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
When all interfaces are connected, check all connections then power on the Cisco Catalyst switch and verify that it is operational.
To check the status of the module, perform these steps:
Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the new module (identified by the designation "QAM") and that the module status is good.
Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer representative. See Obtaining Technical Assistance.
To remove a module from a Cisco Catalyst 4500 series switch, follow these steps:
Step 2 Disconnect any network interface cables attached to the module ports.
Step 3 See Figure 7. With a screwdriver, loosen the captive screws at each end of the module.
Step 4 Move the ejector levers outward to release the module from the backplane connector.
Step 5 Hold the module front panel with one hand, and place your other hand under the module to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 6 Carefully pull the module straight out of the slot, keeping one hand under the module to guide it. See Figure 8.
Step 7 Place the module on an antistatic mat or in an antistatic bag, or immediately reinstall it in another slot.
Step 8 If the slot is to remain empty, install a faceplate (Cisco part number 800-00299-01).
|
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 |
|
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 |
