Placement Consid erations

To prepare to install the VPN 5008 chassis, consider the following items:

Do not place the chassis on the floor, because it can accumulate dust. As alternatives to rack-mounting, you can place it on a sturdy table or platform.
A clean, air-conditioned environment is ideal.
While the chass is does not require rear clearance, the front of the chassis requires adequate clearance for air circulation, module addition or replacement, and cable connections. Allow at least 2 feet of front clearance and 1 inch of top clearance.
If you stack other equipment on the ch assis, do not exceed 35 pounds of evenly distributed weight on top of the chassis. Additional weight may bend the case.

Warning To prevent the VPN 5000 concentrator from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104°F (40°C). To prevent airflow restriction, allow at least 6 inches (15.2 cm) of clearance around the ventilation openings.

Warning The VPN 5000 concentrator must be installed into a rack that is secured to the building structure.

Warning This unit is intended for installation in restricted access areas. A restricted access area can only be entered by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

Warning To prevent bodily injury when you mount or service this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When you mount this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before you mount or service the unit in the rack.

Safety Gui delines

To ensure your safety and minimize potential damage to equipment, follow these guidelines before you attempt to move or work on the VPN 5008 chassis.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Lift the unit only by using handles that are an integral part of the chassis, or by grasping the chassis underneath its lower edge.

Warning Before you work on a chassis or work near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Warning Before you work on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Only trained and qualified personnel should be allowed to install or replace this equipment.

Warning A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the chassis to that receptacle.

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 instal l the handles for a Telco rack, which does not provide enough finger room to use them.

You need a Phillips-head 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 1-1).

Figure 1-1: Installing Chassis Brackets

Step 2 For a standard rack or table o nly, use two provided screws on each side to fasten the handles and spacers to the center of the chassis brackets (Figure 1-2).

Figure 1-2: 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 1-3.

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 1-3: Moving the Cha ssis onto a Table or Platform

Rack-Mounting th e Chassis

You can mount the VPN 5008 chassis in a standard 19-inch equipment rack or in a Telco rack. You need to provide:

At least 18 screws or clips for mounting the brackets to the rack
Phillips-head screwdriver
At least two people to lift the chassis into place

Rack Placement Co nsiderations

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.

Attach ing Rack-Mount Brackets to the Rack

This section describes how to attach the provided rack-mount brackets to the rack. The left bracket features a fold-down shelf that maintains the proper alignment of the brackets in the rack, but does 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.

Step 1 Hand-tighten the right bracket to the rack using your own screws or clips (Figure 1-4).

Use at least two screws to fasten the top of the bracket to the rack using any two holes on the rack tab.
Use at least three screws to fasten the bottom of the bracket to the rack. Use one of the screws to fasten the bottom hole in the rack tab.

Figure 1-4: Fastening the Right Brac ket to the Rack

Step 2 Hand-tighten the left bracket to the rack using your own screws or clips so that the bracket is even with the right bracket (Figure 1-5).

Use two screws to fasten the top of the bracket to the rack using any two holes on the rack tab.
Use at least three screws to fasten the bottom of the bracket to the rack. Use one of the screws to fasten the bottom hole in the rack tab.

Step 3 Lower the shelf onto the t abs protruding from the right bracket.

Step 4 Adjust the bottom of the brackets as shown in Figure 1-6 so that the thumbscrews line up with the tabs on the right bracket.

Figure 1-6: Securing the Shelf

Step 5 Tighten the thumbscrews to secure the shelf to the right bracket.

Step 6 Adjust the top of the brackets so the brackets are straight up and down, and tighten all mounting screws using a screwdriver.

Moving the Cha ssis 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 1-7).

Figure 1-7: Moving the Cha ssis into a Standard Equipment Rack

For a Telco rack, hold the chassis from the bottom and by the side handles (Figure 1-8).

Figure 1-8: Moving the Chassis into a Telc o Rack

Step 2 Slide the chassis into the rack until the chassis brackets are flush with the sides of the rack (Figure 1-9).

Figure 1-9: Placing the Unit in a Rack

Step 3 Using your own screws or clips, secure the chassis brackets to the rack using at least two screws at the top and two screws at the bottom of each bracket (Figure 1-10).

Adding or Replac ing a Module

The chassis ships with the modules you ordered pre-installed. If you want to add or remove a module, you must first disconnect the device. Be sure to keep a cover plate over any empty slots to maintain proper air ventilation and minimize dust accumulation.

To remove and add a module, you need a Phillips-head screwdriver.

Warning Blank faceplates (filler 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 and faceplates are in place.

Warning An uncovered slot is a high energy hazard. Do not place your hand or any object other than a module into a slot. Contact with any interior part could lead to a dangerous shock of electricity.

Step 1 Wear an elect rostatic discharge (ESD)-preventive wrist strap and attach it to ground, such as the metal rack.

Step 2 Loosen the captive thumbscrews on both ends of the module or cover plate you want to remove.

Step 3 Grasping only the handles on both ends of the module or cover plate, slide it out of its slot (Figure 1-11).

Figure 1-11: Removing a Module or Cover Plate

Step 4 Place the module in a rack, a grounded antistatic surface, or other safe place.

Step 5 To add a module to an empty slot, grasp only the handles of the module, and slide it along the guides into the slot.

Step 6 Securely tighten the thumbscrews with the screwdriver.

Connecting the Consol e Cable

To set initial parameters for the system and all modules, connect the provided console cable to the console port on the module in the far left slot, slot 0. While each module includes a console port, only the port in slot 0 controls the entire system.
