Removing and Installing the SA-VAM2

This chapter describes how to remove the Service Adapter VPN Acceleration Module 2 (SA-VAM2) from the supported platforms and how to install a new or replacement SA-VAM2.

Note To ensure proper airflow in the router and compliance with EMI prevention standards, an empty port adapter slot must have a blank port adapter (part number 800-00455-01) installed in it.

The SA-VAM2 circuit board is sensitive to ESD damage.

Handling the SA-VAM2

The SA-VAM2 is a single-width circuit board mounted on a metal carrier. (see Figure 3-1).

Caution

Always handle the SA-VAM2 by the carrier edges and handle; never touch the SA-VAM2 components or connector pins. (See Figure 3-1.)

Online Insertion and Removal (OIR)

Before removing the SA-VAM2, we recommend that you shut down the interface so that there is no traffic running through the SA-VAM2 when it is removed. Removing an SA-VAM2 while traffic is flowing through the ports can cause system disruption.

Caution

The SA-VAM2 supports online insertion and removal (OIR) of the SA-VAM2 in the Cisco 7200 series routers. You do not need to power down the router when removing and replacing the SA-VAM2. However, online removal will disrupt existing tunnels. You will need to reestablish your tunnels. See Site-to-Site and Extranet VPN Business Scenarios at http://www.cisco.com/univercd/cc/td/doc/product/core/7100/swcg/6342gre.htm#xtocid247834 for additional information on configuring tunnels.

Warnings and Cautions

Observe the following warnings and cautions when installing or removing VPN acceleration modules.

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.

Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

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

Warning Keep hands and fingers out of the power supply bays. High voltage is present on the power backplane when the system is running.

SA-VAM2 Removal and Installation

This section describes how to remove and install the SA-VAM2, and covers the following topics:

Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

Note After powering off the router, wait at least 30 seconds before powering it on again.

Cisco 7200 Series Routers

Follow these steps to remove and insert the SA-VAM2 in the Cisco 7200 series routers:

Step 1

Turn the power switch to the off position and then remove the power cable. (Optional on Cisco 7200 series routers; see Caution, above)

Step 2

Attach an ESD wrist strap between you and an unpainted chassis surface.

Step 3

Place the SA-VAM2 retaining lever in the unlocked position. (See 1 in Figure 3-2.)

Step 4

Grasp the handle of the SA-VAM2 and pull the SA-VAM2 from the router. If you are removing a blank port adapter, pull it completely out of the chassis slot.

Step 5

Carefully align the new SA-VAM2 carrier between the upper and the lower edges of the port adapter slot. (See Figure 3-3.)

Caution

To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the SA-VAM2 mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in Figure 3-3.

Step 6

Slide the new SA-VAM2 into the port adapter slot until it is seated in the router midplane.

Caution

Do not allow the SA-VAM2 components to come in contact with the system board or the SA-VAM2 could be damaged.

Step 7

After the SA-VAM2 is properly seated, lock the SA-VAM2 in place, as shown in 2 of Figure 3-2.

Note If a retaining lever does not move to the locked position, the module is not completely seated in the midplane. Carefully pull the module out of the slot, reinsert it, and move the retaining lever or other mechanism to the locked position. See Figure 3-2.

Caution

To ensure the proper flow of cooling air across the internal components, make sure a blank service adapter filler is installed in any unoccupied port adapter slots (part number 800-20675-01).

Reattach the power cable, and place the cable through any cable support brackets.

This completes the removal and installation procedure of the SA-VAM2 from the Cisco 7200 series routers.

Cisco 7301 Router

Use Figure 3-4 and follow the steps below to remove and insert an SA-VAM2 in the Cisco 7301 router:


1	Latch	3	Slot guides
2	SA-VAM2 partially removed	4	Ground for ESD wrist strap banana jack

Step 1

Use an ESD wrist strap to ground yourself to the router. A banana jack ground is to the left of the power switch.

Step 2

To remove a SA-VAM2, use a Phillips screwdriver to turn the screw holding the latch. The screw should be loose enough to allow the latch to rotate to an unlocked position (1). The latch can rotate 360o.

Step 3

Grasp the handle and pull the SA-VAM2 (2) from the router, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter completely out of the chassis slot.

Caution

The SA-VAM2 must slide into the slot guides (3) close to the chassis lid. Do not allow the SA-VAM2 components to come in contact with the system board or the SA-VAM2 could be damaged.

Step 4

To insert the SA-VAM2, carefully align the SA-VAM2 carrier in the slot guides (3), then carefully slide the SA-VAM2 all the way into the slot until the SA-VAM2 is seated.

Step 5

After the SA-VAM2 is properly seated, turn and secure the latch in the upright, locked position (1). Tighten the screw to ensure the SA-VAM2 remains firmly in place.

This completes the removal and installation procedure of the SA-VAM2 from the Cisco 7301 router.
