Product Number: VIP2-10/15/FE2-UPG=
This publication provides instructions for upgrading the dynamic random-access memory (DRAM) on the second-generation Versatile Interface ProcessorVIP2-10 and VIP2-15 and the second-generation Fast Ethernet Interface Processor (FEIP2). (For convenience, the VIP2-10, VIP2-15, and FEIP2 are hereafter referred to as the interface processor, with differences noted.)
This DRAM upgrade is required only if you have any one of these interface processors installed in your Cisco 7000 series or Cisco 7500 series router, and if your router is running any of the Cisco IOS Release 12.0-based software images. The DRAM upgrade requires you to remove the interface processor from the system in which it is installed; therefore, to minimize network downtime, we strongly recommend that you plan your upgrade accordingly, and upgrade several simultaneously.
This publications includes the following sections:
To determine whether a DRAM upgrade is required, you must determine what type of interface processors are installed in your system, and then determine your Cisco IOS software release.
Note We strongly recommend that you upgrade VIP2-10, VIP2-15, or FEIP2 DRAM if you have any one of these interface processors installed in your Cisco 7000 series or Cisco 7500 series router, and if your router is running any of the Cisco IOS Release 12.0-based software images.
If one of these interface processors is installed in your Cisco 7000 series or Cisco 7500 series router, and your router is running a Cisco IOS Release 12.0 software image, you will see the following display at system startup:
Note If you see the preceding display, you must upgrade your VIP2-10, VIP2-15, or FEIP2 DRAM to be able to use a Cisco IOS Release 12.0 software image with these interface processors.
To determine the type of interface processors installed in your system, use the show diag slot command, where slot is an interface processor slot number in your router. You can also use the show diag command without the slot argument to display all the interface processors in your router.
Note If you determine that you require the interface processor DRAM upgrade, proceed to the following sections of this publication to perform the upgrade.
You need the following tools and parts to upgrade DRAM on your interface processor:
If you need additional equipment, contact a service representative for ordering information.
Following are safety guidelines that you should follow when working with any equipment that connects to electrical power, or which might be sensitive to electrostatic discharge (ESD) damage.
Follow these basic guidelines when working with any electrical equipment:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures.
Use the following guidelines for preventing ESD damage:
Warning For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 Megohms (Mohms). |
This section describes the procedure required to remove the interface processor from your system. You do not need to shut down interfaces or system power before you remove an interface processor.
Figure 1 shows proper handling of an interface processor during removal and reinstallation. Interface processors are oriented horizontally in Cisco 7010 and Cisco 7505 routers, and are oriented vertically in Cisco 7000, Cisco 7507, Cisco 7513, and Cisco 7576 routers.
Note We strongly recommend that you remove interface processors starting with the slots closest
to the RSP or RSP7000.
Make a note of which slots your interface processors occupy so you can reinstall them in these same
slots later.
Use the following procedure to remove an interface processor:
Step 2 Disconnect all cables from the interface processor ports.
Note Although we strongly recommend that you remove cables from the interface processorand doing so makes interface processor removal easierthis step is not required.
Step 3 Use a screwdriver to loosen the captive installation screws at both ends of the interface processor. (See Figure 2.)
Caution Always use the ejector levers to remove or install an interface processor. Failure to do so can cause erroneous system messages indicating an interface processor failure. |
Step 4 Place your thumbs on the ejector levers and simultaneously pull both of the ejector levers outwardin the direction opposite of that shown in Figure 2cto release the interface processor from the backplane connector.
Step 5 Grasp the interface processor handle carefully with one hand and pull the interface processor straight out of the slot; keep your other hand under the carrier to guide it.
(See Figure 1.) Keep the interface processor parallel to the system backplane. Avoid touching the interface processor printed circuit board or any connector pins.
Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only. |
Step 6 Place the removed interface processor on an antistatic mat or antistatic foam pad.
Step 7 Repeat Steps 1 through 6 for each interface processor you plan to upgrade.
This completes the procedure for removing the interface processor. Proceed to the following section, "Upgrading DRAM."
This section provides guidelines and the procedure for upgrading DRAM on the interface processor. The DRAM upgrade increases total interface processor DRAM from 8 MB to 16 MB. The DRAM upgrade kit VIP2-10/15/FE2-UPG= contains two 8-MB DRAM SIMMs.
The DRAM on the interface processor is contained in two 70-nanosecond (ns) SIMMs located in sockets U2 and U6. Figure 3 shows the locations of the DRAM SIMMs on the interface processor.
Note This procedure requires you to remove the two 4-MB DRAM SIMMs from sockets U2 and U6 and replace them with two 8-MB SIMMs.
Caution To prevent ESD damage, handle DRAM SIMMs by the card edges only. Place removed SIMMs on an antistatic mat and store them in an antistatic bag. |
This section provides the procedure for removing the DRAM SIMMs, which are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM).
(See Figure 4.)
Caution To prevent ESD damage, handle SIMMs as shown in Figure 4. |
Use the following procedure to remove the SIMMs:
Step 2 Position the interface processor with the handle away from you and the bus connector toward you.
Step 3 Locate the DRAM SIMMs. The SIMMs occupy sockets U2 and U6.
(See Figure 3.)
Note You must replace the two 4-MB DRAM SIMMs in SIMM sockets U2 and U6 with the two 8-MB DRAM SIMMs included in your DRAM upgrade kit.
Step 4 Release the spring clips from the SIMM in socket U6 and release the SIMM from the socket. (See Figure 5.)
Step 5 Grasp the ends of the SIMM with your thumb and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only; avoid touching the memory module or pins, and the metal traces, or fingers, along the socket edge.
Step 6 Place the SIMM in an antistatic bag to protect it from ESD damage.
Step 7 Repeat Step 1 through Step 6 for the second SIMM.
This completes the procedure for removing the old DRAM SIMMs. Proceed to the following section to install the new DRAM SIMMs.
This section provides the procedure for installing the new DRAM SIMMs.
Caution To prevent ESD damage, handle SIMMs as shown in Figure 4. |
Use the following procedure to install new SIMMs:
Step 2 Position the interface processor as in the previous procedure (with the handle away from you and the bus connector toward you).
Step 3 Remove a new SIMM from its antistatic bag or box.
Step 4 Hold the SIMM between your thumbs and forefingers, component side up, with the connector edge (the metal fingers) away from you. (See Figure 4.)
Step 5 Tilt the SIMM to approximately the same an angle as the socket and insert the connector edge of the SIMM into the socket.
Install the first SIMM in the socket farthest from you (U2) and install the second SIMM in the socket closest to you (U6).
Caution Use firm but not excessive pressure when you insert SIMMs. If you damage a socket, you must return the entire interface processor to the factory. |
Step 6 Push the SIMM gently into the socket until the spring clips snap over the ends of the SIMM. If necessary, rock the SIMM gently back and forth to seat it properly.
(a). When the SIMM is installed, check the two alignment holes and ensure that the spring retainer is visible. If it is not, the SIMM is not seated properly.
(b). If any SIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SIMM firmly back into the socket until the retainer springs snap into place.
Step 7 Repeat Step 1 though Step 6 for the second SIMM.
This completes the procedure for installing the new DRAM SIMMs. Proceed to the following section, "Installing an Interface Processor."
This section provides the procedure for installing the interface processor after you complete the DRAM upgrade.
Figure 1 shows proper handling of an interface processor during installation. Figure 2 shows proper use of the captive installation screws and ejector levers.
Note We strongly recommend that you install interface processors starting with the slots closest to
the RSP or RSP7000, and work out concentrically from there. This helps ensure protection against
electromagnetic interference (EMI).
Refer to the notes you made before you removed the interface processors, so you can install them in
the correct slots.
Use the following procedure to install an interface processor:
Step 2 Ensure that a console terminal is connected to the console porton the RSP or RSP7000and that your console terminal is turned on.
Step 3 Hold the interface processor handle with one hand and place your other hand under the carrier to support the interface processor; guide it into the slot. (See Figure 1.) Avoid touching the interface processor printed circuit board or any connector pins.
Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only. |
Step 4 Place the back of the interface processor in the slot and align the notch on the carrier with the groove in the slot. (See Figure 2.)
Step 5 While keeping the interface processor parallel to the backplane, carefully slide the interface processor into the slot until the back of the faceplate makes contact with the ejector levers; and then stop. (See Figure 2b.)
Step 6 Using your thumbs, simultaneously push both ejector levers inward until the interface processor is pushed entirely into its slot. (See Figure 2c.)
Step 7 Tighten both of the captive installation screws.
Caution To ensure proper electromagnetic interference (EMI) isolation for the chassis, make certain to tighten the captive installation screws on the interface processor immediately after you install it and before proceeding with the installation of any remaining interface processors. |
Step 8 Repeat Step 1 through Step 7 for each interface processor you removed to upgrade.
This completes the procedure for installing the interface processor. Proceed to the following section, "Checking the DRAM Upgrade."
After you upgrade DRAM on the interface processor and reconnect cables, verify the upgrade by observing the LED states and the console terminal display. When the system has reinitialized all interfaces, the enabled LED on the interface processor (and on all interface processors) should go on. If the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:
If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.
Use the following procedure to verify that the interface processor is operating properly:
Step 2 When the reinitialization is complete, verify that the enabled LED on each interface processor goes on and remains on.
Step 3 If the enabled LED fails to go on, suspect that the interface processor backplane connector is not fully seated in the backplane. Loosen the captive installation screws, and then firmly push both ejector levers into place until they are parallel to the faceplate. Tighten the captive installation screws.
After the system reinitializes the interfaces, the enabled LED on the interface processor should go on.
Step 4 If the enabled LED still fails to go on, remove the interface processor and try installing it in another available interface processor slot.
(a). If the enabled LED goes on when the interface processor is installed in the new slot, suspect a failed backplane port in the original interface processor slot.
(b). If the enabled LED still fails to go on, but other LEDs go on to indicate interface activity, proceed to Step 5, and suspect that the enabled LED on the interface processor has failed.
(c). If no LEDs on the interface processor go on, suspect that the interface processor is faulty.
(d). If the enabled LED still does not go on, contact a service representative to report the problem and obtain further instructions.
Step 5 When the interfaces are up, check the activity of each interface by observing the status LEDs on the interface processor, which are described in the appropriate LED section of the configuration note that shipped with your interface processor or port adapter.
Note In general, if an interface LED fails to go on and a cable is connected to the port, check the cable connection and make certain it is properly seated in the connector.
If you experience other problems that you are unable to solve, contact a service representative for assistance. This completes the DRAM SIMM upgrade.
