Cisco RF Gateway 10 Hardware Installation Guide

Installing a DC PEM

This section describes how to install a DC PEM.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022

Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045

Warning Use copper conductors only. Statement 1025

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002

To install a DC PEM, connect it to a power source, and verify its operation, do the following:

Before proceeding, read the following instructions:

• The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground (GND), black for –48V on negative (–) terminal and red for RTN on the positive (+) terminal. Ensure that the lead color coding you choose for the DC-input power supply matches the lead color coding used at the DC power source.
• For DC-input power cables, select the appropriate wire gauge based on the National Electrical Code (NEC) and local codes for 60-amp service at nominal DC-input voltage (–48 VDC). Two pairs of cable leads - source DC (–) and source DC return (+), are required for each Power Distribution Unit (PDU). These cables are available from any commercial cable vendor. All input power cables for the chassis must have the same wire gauge and the cable lengths must match (with a 10 percent deviation). Each DC-input power cable is terminated at the PDU by a cable lug (included in the accessory kit). The cable lugs must be dual-hole, and have a 90 degree tongue (reference Panduit LCD4-14AF-L). They must fit over M6 terminal studs at 0.625-inch (15.88-mm) centers.

Note The DC-input power cables must be connected to the PDU terminal studs in the proper positive (+) and negative (–) polarity. In some cases, the DC cable leads are labeled, which is a safe indication of the polarity. However, you must verify the polarity by measuring the voltage between the DC cable leads. While measuring, the positive (+) lead and the negative (–) lead must always match the (+) and (–) labels on the PDU.

• An earth ground cable is required for each DC PDU. We recommend that you use at least 4-AWG multi-strand copper wire. This wire is not available from Cisco; it is available from any commercial cable vendor.

The ground wire cable lug (provided in the accessory kit) should be dual-hole, 90 degree tongue (reference Panduit LCD4-14AF-L), and fit over M6 terminal studs at 0.625 inch (15.88mm) centers.

Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 1046

Note To avoid hazardous conditions, all components in the area where DC input power is accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according to the manufacturer's instructions.

Step 1 Ensure that the facility that feeds the DC -48V power supply to the chassis is turned off.

Step 2 Ensure that the breaker on the PEM power supply is turned off.

Step 3 Make sure that the chassis grounding is connected before you begin installing the DC power supply.

Step 4 Grasp the power supply handle with one hand. Place your other hand underneath it as you slowly insert the power supply into the bay. Do not fully install the DC power supply to the midplane connector, leave the power supply disconnected from the chassis by 1 inch.

Step 5 Locate the stud on the DC power supply for the GND connection, which must be connected first and follow these steps:

a. Using the provided grounding lug in the accessory kit, replace the washers and Kepnut screw in the following order:

– Washer

– Grounding cable lug

– Kepnut screw

b. Tighten the Kepnut screws on the power supply studs to the recommended torque of 18 in-lbs minimum to 22 in-lbs maximum.

Step 6 Attach the other end of the cable to the site ground connection.

Step 7 Before you connect the power supply to a power source, ensure that all site power and grounding requirements are met.

Step 8 Remove or rotate the plastic cover from the terminal block.

Note To avoid hazardous conditions, all components in the area where DC input power is accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according to the manufacturer's instructions.

Step 9 Insert the negative lead cable first. Replace the ground lug with cable in the following order:

a. Washer

b. Ground lug with negative wire

c. Kepnut screw

Step 10 Tighten the Kepnut screw to the recommended torque of 18 in-lbs minimum to 22 in-lbs maximum.

Step 11 Repeat Step 7 and Step 8 for the RTN lead cable.

Note Secure the wires coming in from the terminal block so that they are not disturbed by casual contact.

Step 12 Replace and rotate the terminal block plastic cover back into position until it is locked.

Note Both DC inputs to the DC PEM must be connected and energized for the Cisco RFGW-10 UEQAM system to operate properly.

Step 13 Fully install the DC PEM into the power supply bay and tighten the captive fasteners on the faceplate to the chassis.

Step 14 Tighten the DC PEM captive fasteners to 12-16 in-lb torque.

Note Both DC inputs to the DC PEM must be connected and energized for the Cisco RFGW-10 UEQAM system to operate properly.

Step 15 Energize the facility DC power feeds to the power supply.

Step 16 Verify power supply operation by checking the power supply’s front panel LEDs. The –48 V1 and –48 V2 LEDs should illuminate green.

Step 17 Switch the circuit breaker switch to the On (|) position.

Step 18 Again verify the power supply operation by checking the power supply’s front panel LEDs. The –48 V1, –48 V2 and OUTPUT OK LEDs should illuminate green.

Step 19 Check the power supply and system status from the system console by entering the show power command. For more information on the commands, refer to the command reference publication for your chassis and software.

Removing a DC PEM

This section describes how to remove a DC PEM.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003

Step 1 Turn off the PEM in-line power switch.

Step 2 Ensure that the facility that feeds the DC -48V power supply to the chassis is turned off.

Step 3 Verify that power is off to the DC circuit on the power supply you are removing.

Note To meet the electromagnetic interference (EMI) requirements, the DC power supply should be removed from the chassis if the PEM has failed or the circuit breaker is off.

Step 4 Unscrew the top left-hand side captive fastener on the power supply faceplate (thumb screw) first, then unscrew the bottom right-hand side captive fastener.

Wait for five seconds.

Step 5 Grasp the power supply handle with one hand and pull until you feel the power supply disconnect from the midplane connector and move freely (approximately 1” removal from the chassis).

Step 6 Unhinge the terminal covers from the terminal blocks to expose the terminal block studs.

Step 7 Using a socket wrench and 10 mm socket disconnect the kepnut retaining the DC-input lugs from the terminal block.

Step 8 Repeat Step 6 and Step 7 for the second terminal block.

Step 9 Using a socket wrench and 10 mm socket disconnect the kepnut retaining the DC PEM ground lug from the power supply faceplate.

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Step 10 Grasp the power supply handle with one hand. Place your other hand underneath as you slowly pull the power supply out of the bay.

Step 11 If the bay is to remain empty, install a blank power supply filler plate over the opening and secure it with the mounting screws. This protects the inner chassis from dust and prevents accidental contact with live voltage at the rear of the bay.

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

Removing the Fan Assembly

Follow these steps to remove the existing chassis fan assembly:

Step 1 Loosen the three captive installation screws on the fan assembly front panel by turning them counterclockwise (see Figure 5-2).

Figure 5-2 Cisco RFGW-10 UEQAM System Fan Assembly

Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258

Step 2 Grasp the fan assembly handles with both hands and pull it outward to disengage the midplane connector. Slide it out of the chassis and place it in a safe place. Do not touch the fans, hold the fan tray by the handles only.

Installing the Fan Assembly

Follow these steps to install the new fan assembly:

Step 1 Place the fan assembly into the fan assembly bay so it rests on the chassis, and then lift the fan assembly up slightly, aligning the top and sides with the bay opening.

Step 2 Gently slide the fan assembly into the chassis until the fan tray front panel makes contact with the chassis.

Note Apply a slow and even pressure on the fan assembly handles so that the fan tray does not tilt from side-to-side.

Step 3 Using a screwdriver, tighten the three front panel captive screws by turning them clockwise.

Note Tighten the fan tray captive screws to 6-8 in-lbs.

Verifying the Fan Assembly Installation

Note To check the operation of the fans, you need to power up the chassis.

Follow these steps to verify that the new fan assembly was installed correctly:

Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan assembly is inserted completely in the chassis and that the faceplate is flush with the chassis back panel.

Note The fan tray has multiple speeds based on the ambient air temperature conditions. The default control mode setting configures the fans at a maximum speed at startup. After startup, it may take up to 30 seconds for the fans to stabilize to the requested RPM.

Step 2 The fan tray LED should illuminate green.

Step 3 If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.

Installing the Supervisor Cards

The Cisco RFGW-10 UEQAM has vertical chassis slots that are numbered from left to right. The Supervisor Cards can be installed only in Slot 1 and/or 2.
