Mounting the Cisco 6705 Chassis and Battery Box

The following sections describe mounting procedures for the Cisco 6705 and battery box:

Wall Mounting

A piece of 3/4-inch plywood, painted with fire retardant paint, must be used between the chassis and the wall.

Step 1 Put the wall mounting template on a 3/4-inch plywood board painted with fire retardant paint.

Step 2 Use the template as a guide to drill holes for the mounting wood screws.

Step 3 Hold the Cisco 6705 chassis against the plywood, and use the four wood screws to fasten the chassis to the plywood.

Caution To prevent thermal damage to the Cisco 6705, the top of the unit must remain clear at all times. No objects (papers, tools, or other network elements) should be placed on top of the Cisco 6705. The open top chassis design allows the Cisco 6705 to maintain acceptable operating temperatures.

Step 4 Repeat these steps for the battery box. The battery box should be mounted approximately 6 to 8 inches below the Cisco 6705 chassis.

Rack Mounting

The Cisco 6705 integrated access device chassis is equipped with dual-purpose mounting ears. Before mounting the Cisco 6705 chassis in a 19-inch rack, the mounting ears must be removed and reattached to the chassis. (See Figure 1-2.)

Figure 1-2: Cisco 6705 Mounting Ears Configured for 19-inch Rack Mount

Complete the following tasks to mount the Cisco 6705 in a 19-inch rack:

Step 1 Place the provided set screws (12-24 x 3/4 inch) in the desired holes on the rack. The set screws hold the Cisco 6705 in place while the rack screws are being inserted.

Step 2 Place the Cisco 6705 on the set screws.

Step 3 Secure the Cisco 6705 to the rack with the four provided rack screws (12-24 x 3/8 inch).

Note The battery box is not configured for mounting in a 19-inch rack. Cisco Systems recommends that you place the battery box on a rack shelf near the Cisco 6705 chassis.

Connecting Power and Ground Wiring

Figure 1-3 shows the power and ground connectors on the Cisco 6705 chassis.

Figure 1-3: Cisco 6705 Power and Line Interface Module Connectors

To connect power and ground wiring for the Cisco 6705 and battery box:

Step 1 Connect the green earth ground wire from the Cisco 6705 chassis to the rack, the grounding busbar, or any appropriate earth ground.

Step 2 To test the ground wiring, use a digital multimeter to test the Cisco 6705 chassis against the equipment rack. Resistance should be less than 1 ohm.

Step 3 Connect the AC power cord from the BPS/AC to a 110 VAC power source.

Step 4 The green PWR LED will light immediately. This indicates that the module is receiving.

Note Any further LED activity on the BPS-AC module indicates module or system status. See Chapter , "Product Overview," for LED information for the BPS-AC module.

Step 5 Connect the battery box output power cable to the battery box terminal on the Cisco 6705 chassis.

Inserting Service Modules and Line Interface Modules

Caution To prevent electrostatic discharge damage to the Cisco 6705 chassis and components, you must wear an ESD-preventative strap when inserting or removing modules. Place the strap on your wrist, and connect the wire an appropriate ground, such as an equipment. The Cisco 6705 chassis provides a strap insert connection located directly above the BPS-A card slot, at the upper left corner of the chassis.

To insert a service module or line interface module:

Step 1 Identify an open slot in the chassis that supports the service module or line interface module. See Chapter , "Product Overview," for service module and line interface module requirements.

Step 2 Attach an ESD-preventive strap between you and the chassis surface.

Step 3 Hold the service module vertically, with the faceplate toward you and the backplane connectors away from you. Ensure that the module is right side up by noting the lettering on the faceplate.

Step 4 Carefully align the upper and lower edges of the module with the upper and lower guides in the chassis.

Step 5 Gently slide the module into the slot until the lever (at the upper left of the module faceplate) touches the chassis.

Step 6 Lift the lever up and slide the module into the slot until it makes contact with the backplane.

Step 7 Secure the module by pressing the lever down.

Step 8 Connect any cables to cable interfaces on the faceplate.

Removing a Service Module or Line Interface Module

To remove a service module or line interface module:

Step 1 Attach an ESD-preventive strap between you and the chassis surface.

Step 2 Remove any connections to the module. Be sure to cover any fiber optic connections to prevent contamination from moisture or dirt.

Step 3 Lift the lever up to unseat the module.

Step 4 Grasp the module faceplate, and carefully slide the module out of the slot. Avoid damaging the connectors on the rear of the module.

Step 5 Place the module on an anti-static surface.

Module Insertion Order

Service modules and line interface modules must be inserted into the chassis in the following order:

1. Main Control Card (MCC-INT) module in slot MCC

2. Remaining service modules and line interface modules in available general-purpose slots.

Troubleshooting

If the PWR LED does not light, the BPS-HP is not receiving a minimum of -42.5VDC. Measure the input power terminals on the backplane to determine if the Cisco 6732 is receiving a minimum input of -42.5 VDC.

The FUSE LED illuminates if one of the three card fuses is blown.

Note These fuses are not field replaceable.

If a BPS-HP card senses an output short or overvoltage, the module shuts down (providing no voltage to power the LEDs).

If the module fails, remove the module and then reseat it in the bank. If the failure persists, replace the BPS-HP and contact the Cisco Systems technical assistance center (TAC).

Inserting the MCC-INT Module

When you insert an MCC-INT module in slot MCC, the following initialization sequence occurs:

1. The red FAIL LED will light immediately.

2. All LEDs on the MCC-INT module then light up simultaneously and turn off.

3. The LEDs will perform a "walk-up" sequence, beginning from the bottom LED (SYNC) to the top LED (FAIL).

4. After the walk-up sequence is completed, the red FAIL LED and the green ACTV LED will remain on while the MCC-INT module boots up and achieves active status. The boot-up process might take 20 to 30 seconds to complete.

5. When boot-up is complete, the green ACTV LED will light and remain on.

6. After the MCC-INT module boots up, the green BUSY LED on the BPS-AC module should light. The BUSY LED indicates that the BPS-AC module is supplying power to the MCC-INT module.

Any further LED activity indicates module or system status. See Chapter , "Product Overview," for LED information for the MCC-INT module.

Inserting a Line Interface Module

When you insert a line interface module in an available general-purpose slot, the following initialization sequence occurs:

1. The red FAIL LED and the green BUSY LED light and remains on while the module downloads the internal software from the active MCC module.

2. After download, all of the LEDs will flash in sequence from top to bottom.

Any LEDs that remain lit after initialization indicate module or line status. See Chapter , "Product Overview," for LED information for each line interface module.
