Figure 10 Plugging the Power Connectors into the Chassis

Step 8 Turn on the DC power source.



Warning After you wire the DC power supply, remove the tape from the circuit breaker switch handle. Reinstate power by moving the handle of the circuit breaker to the On position.


Wiring the Alarm Connectors

The VPN 5008 concentrator -48 VDC power supplies include three receptacles for alarm connectors: one each for critical, major, and minor alarms. In the event of a power interruption or system failure, the appropriate alarm activates.

The minor alarm activates if any power supply malfunctions. The major alarm activates if both power supplies malfunction. The critical alarm is currently unused.

The alarm relay switches support the following positions:

Normally open alarm—A device that has an open contact when there is no alarm.

Normally closed alarm—A device that has a closed contact when there is no alarm.

Figure 11 shows the wire locations for the alarm connectors on the right power supply. Figure 12 shows the wire locations for the alarm connectors on the left power supply.

Figure 11 Alarm Connector Wiring for the Right Power Supply

Figure 12 Alarm Connector Wiring for the Left Power Supply

To wire the alarm connectors


Step 1 Strip 0.125 inches (.3175 cm) of the insulation from the end of two 14 AWG wires. Do not strip more than 0.125 inches.

Step 2 Insert a medium flat-blade screwdriver into the connector middle hole and loosen the screw (Figure 13).

Figure 13 Loosening the Screw

Step 3 Insert one wire to serve as the COMM wire into the middle slot while tightening the screw (Figure 14).

Figure 14 Attaching the COMM Wire

Step 4 Loosen the screw (Figure 13) for the appropriate slot and insert the other wire while you tighten the screw. The COMM wire is always in the middle slot.

For a normally closed alarm, insert the wire into the bottom slot.

For a normally open alarm, insert the wire into the top slot.

Step 5 Plug the alarm connectors into the top connector on the left power supply and the top and middle connectors on the right power supply (Figure 15).


Note To avoid activating the alarm during power supply installation, plug in the alarm connectors after you turn on the power.


Figure 15 Plugging the Alarm Connectors into the Chassis


Resetting the Power Alarm

The power supply alarm activates in the event of a power interruption or malfunction. Use the alarm cut-off button on the left power supply (Figure 16) to deactivate the alarm and enable it again.

Figure 16 Alarm Cut-Off Button

If the system is still running despite alarm activation, it was probably disrupted by a temporary power failure. Press the alarm cut-off button to reactivate the alarm after an event.

If the system is not running, the cause of the alarm is either a continuing power failure or a catastrophic system failure. To determine the cause of the alarm, check the LEDs on the power supplies:

If the DC Power LED is off, the DC power source is not functioning. Check the power source. If the power is disrupted, restore it to reboot the system.

If the Power LED is off on both supplies while the DC power LED is on, the cause of the alarm is probably a catastrophic system failure. Contact the Cisco Technical Assistance Center.

Attaching the Connector Restraints

After the alarm connectors and power supply connectors are plugged in to the chassis, attach the connector restraints. The connector restraints prevent the alarm connectors and power supply connectors from being pulled out (Figure 17).

Have the following provided parts available:

One left-side connector restraint and thumbscrew

One right-side connector restraint and thumbscrew

To attach the connector restraints


Step 1 Insert the tabbed bottom portion of the connector restraints into the slots located directly below the power connectors on the VPN 5008 chassis.

Step 2 Cover the alarm and power connectors with a restraint.

For the left-side restraint, make sure the alarm cut-off button shows through the hole in the top of the restraint.

Step 3 Use the thumbscrews to tighten the connector restraints to the chassis (Figure 17).

Figure 17 Attaching the Connector Restraints


Rack-Mounting Kits

Product Number: ACS-CVPN5008-RM

This section describes how to install brackets and handles on the VPN 5008 chassis, the proper method for moving the chassis, and how to mount the chassis in a rack.

Installing Chassis Brackets and Handles

Install the chassis brackets and handles on the VPN 5008 chassis even if you do not plan to mount it in a rack. Do not install the handles for a telco rack, which does not provide enough finger room to use them.

You need a Phillips screwdriver to complete the following procedure.


Step 1 To fasten the chassis brackets to the sides of the chassis, use five provided screws on each side.

Use the front holes for a standard rack or table, and the middle holes for a telco rack (Figure 18).

Figure 18 Installing Chassis Brackets

Step 2 For a standard rack or table only, use two provided screws on each side to fasten the handles and spacers to the center of the chassis brackets (Figure 19).

Figure 19 Installing Handles for a Standard Rack or Table


Moving the Chassis to a Table or Platform

After you attach the brackets, use two people to move the chassis to a table or platform by holding the front and side handles as shown in Figure 20.


Warning Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back.


Figure 20 Moving the Chassis onto a Table or Platform

Rack-Mounting the Chassis

You can mount the VPN 5008 chassis in a standard 19-inch equipment rack or in a telco rack. You must provide:

At least 18 screws or clips for mounting the brackets to the rack

Phillips screwdriver

At least two people to lift the chassis into place

Rack Placement Considerations

Before you mount the chassis, consider the following rack guidelines:

Use an open equipment rack (one without side enclosures or doors) for adequate ventilation.

The chassis requires 14 rack units (23.5 vertical inches, 59.69 cm) of rack space.

Load the equipment rack from the bottom. For stability, place the VPN 5008 chassis in the lower half of the equipment rack.

Attaching the Rack-Mount Brackets and Shelf to the Rack

This section describes how to attach the provided rack-mount brackets and shelf to the rack. The brackets and shelf maintain the proper alignment, but do not bear the weight of the chassis. The ledges at the bottom of the brackets bear the weight of the chassis until it is securely attached to the equipment rack.

To attach the brackets and shelf


Step 1 Hand-tighten the brackets to the rack using your own screws or clips (Figure 21). Be sure that the brackets are placed evenly on the rack.

Use at least two screws to fasten the top of each bracket to the rack. You can use any two holes on the rack tab.

Use at least three screws to fasten the bottom of each bracket to the rack. Use one of the screws to fasten the bottom hole in the rack tab.

Figure 21 Fastening the Brackets to the Rack

Step 2 Lower the shelf onto the tabs protruding from the right bracket.

Step 3 Adjust the bottom of the brackets as shown in Figure 22 so that the four thumbscrews on the shelf line up with the tabs on the brackets.

Figure 22 Securing the Shelf

Step 4 Tighten the four thumbscrews to secure the shelf to the brackets.

Step 5 Adjust the top of the brackets so that the brackets are straight up and down, and then use a screwdriver to tighten all mounting screws.


Moving the Chassis into the Rack

After you attach the brackets, complete the following steps to install the chassis in a rack.


Step 1 Using two people, carefully lift the chassis and place it into the brackets.


Warning Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back.


For a standard rack, hold the chassis by the front and side handles (Figure 23).

Figure 23 Moving the Chassis into a Standard Equipment Rack

For a telco rack, hold the chassis from the bottom and by the side handles (Figure 24).

Figure 24 Moving the Chassis into a Telco Rack

Step 2 Slide the chassis into the rack until the chassis brackets are flush with the sides of the rack (Figure 25).

Figure 25 Placing the Unit into a Rack

Step 3 Using your own screws or clips, secure the chassis brackets to the rack. Use at least two screws at the top and two screws at the bottom of each bracket (Figure 26).

Figure 26 Securing the Chassis to the Rack


Fan Tray Assembly

Product Number: ACS-CVPN5008-FAN

This section describes how to install and replace the fan tray assembly.

To replace the fan tray assembly


Step 1 Loosen the two thumbscrews and remove the bottom panel on the concentrator (Figure 27).

Make sure the connector wire is positioned in the slot at the back of the fan tray (Figure 30).

Figure 30 Positioning the Wire and Connector

Step 6 Use two screws to fasten the fan tray to the chassis.

Step 7 Replace the cover plate and fasten the thumbscrews.


Replacing the Filter Foam

Product Number: ACS-CVPN5008-FILTER

This section describes how to replace the Cisco VPN 5008 chassis air filter.

Under normal operation, you do not need to replace the air filter. Replace the filter only if an excessive amount of dirt and dust collects over an extended period of time, or if a lit Over Temp LED appears on an ESP card. See the Cisco VPN 5002 and 5008 ESP Card Hardware Guide for more information about resolving a high-temperature condition.

Cisco Systems provides an extra filter with each unit to minimize the platform down time.

To change the filter, complete these steps:


Step 1 Remove the bottom panel by loosening the two captive thumbscrews (Figure 31).

Figure 31 Replacing the Filter Foam

Step 2 Remove the filter from its slot.

Step 3 Put the supplied replacement filter in the slot.

Step 4 Replace the bottom panel and securely tighten the captive thumbscrews.

If you want to reuse the old filter, wash it in warm, soapy water and allow to completely dry. If either of the supplied filters is worn out or cannot be thoroughly cleaned, you can order a replacement filter from Cisco Systems.
