Installing and Removing DRAM DIMMs

Cisco 2801 routers have 128 MB of SDRAM installed on the system board. You can install an additional DIMM in the DIMM connector to expand system memory to a maximum of 384 MB.


Note The Cisco 2801 uses a different type of DRAM DIMM than the Cisco 2811, Cisco 2821, and Cisco 2851 routers. Refer to the Router Memory Specifications table in the Overview of 2800 Routers chapter for DRAM information.


Cisco 2811, Cisco 2821, and Cisco 2851 routers have two DIMM connectors and are designed to operate with either one or two DRAM DIMMs installed, depending on the amount of memory needed. If only one DRAM DIMM is used, it can be installed in either DIMM connector.

Before you remove or install a DRAM DIMM, remove the chassis cover as described in the "Removing the Chassis Cover" section.


Caution When you remove or install DIMMs, always wear an ESD-preventive wrist strap, and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the chassis.


Caution Handle DRAM DIMMs by the edges only. DIMMs are ESD-sensitive components and can be damaged by mishandling.

DRAM DIMM Location and Orientation

On Cisco 2801 routers, the single DRAM DIMM connector is located on the system board. Refer to Figure 8 for the location of the DIMM connector.

On Cisco 2811, Cisco 2821, and Cisco 2851 routers, the two DRAM DIMM connectors are located on the system board, and are identified as DIMM 0 and DIMM 1. Refer to Figure 9, Figure 10, and Figure 11 for the location of the DIMM connectors.

DRAM DIMMs have a polarization notch on the mating edge to prevent incorrect insertion. Figure 12 shows the polarization notch on a DRAM DIMM.

Step 3 Carefully lift the AIM free from the connector and the plastic standoff. Keep the AIM parallel with the system board to prevent damage to the connector and plastic standoff.

Step 4 Place the AIM in an antistatic bag to protect it from ESD damage.


Installing an AIM

To install an AIM, perform the following procedure. To complete this procedure, you need a number 2 Phillips screwdriver or flat-blade screwdriver, and a 1/4-inch nut driver or wrench.

Installing an AIM in a Cisco 2801 Router

The Cisco 2801 router has two AIM connectors—AIM slot 0 and AIM slot 1. To install these AIMs, follow the procedures given here.

Accessory Kit to Use

Some AIMs are provided with multiple accessory kits that contain different configurations of mounting hardware. The mounting hardware required to install an AIM in the Cisco 2801 router consists of two machine-thread metal standoffs, two machine-thread metal screws, and one plastic standoff with a snap fit on both ends. All these components are included in mounting kit 69-1316-01. Some AIMs, however, are shipped with multiple, different mounting kits. If this is the case, use the plastic standoff with a snap fit on both ends from mounting kit 69-0900-01 and the two machine-threaded metal standoffs and two metal screws found in mounting kit 69-0899-01.

To install the AIM2-CUE-K9 and the AIM2-APPRE-104-K9 modules in a Cisco 2801 router, use the blue plastic standoff, 2 larger screws, and hex standoffs in the 69-1870-01mounting kit.

Installation Procedure

To install the AIM, perform the following steps. You need a number 2 Phillips screwdriver or flat-blade screwdriver to complete this procedure.


Note For most AIMs, the plastic snap-in standoff is white. For the AIM2-CUE-K9 and the AIM2-APPRE-104-K9, the plastic standoff is blue and has a slightly larger snap-in feature to accomodate the PCB which is thicker.



Step 1 Find the standoff attachment locations on the system board near the AIM connector, indicated by a star pattern. Figure 18 shows the four standoff locations on the system board.

Figure 18 Connecting the AIM to the Cisco 2801 System Board

Step 2 Locate the two machine-thread metal standoffs from the accessory kit. Do not use sheet metal-thread standoffs. See Figure 19 for an illustration of the different metal standoffs.

Figure 19 Metal Standoffs

Step 3 Install the two machine-thread metal standoffs into the system board in the metal standoff attachment locations, as shown in Figure 18. Use a 1/4-inch nut driver to tighten the standoffs. Locations for AIM standoffs are denoted by a star pattern around the standoff mounting holes.


Caution Make sure that the standoffs are straight when installed. Tighten them gently but firmly. The shoulder must be seated tightly against the system board.

Step 4 If you have a Cisco 2801 router, insert the plastic standoff with a snap fit on the ends (see Figure 20) from the accessory kit into the hole in the system board. See Figure 18. Press the standoff firmly into the system board to be sure that it is locked to the board.


Note The Cisco 2801 router does not have a screw in the spot labeled B in Figure 22. Instead, there is a hole in the system board in approximately the same location. Insert the plastic standoff in the hole in the system board on Cisco 2801 routers.



Note The plastic standoff snaps into the system board. Be sure to insert the locking end of the standoff into the system board. The locking end is the shortest end of the standoff. Figure 20 identifies the locking end of the plastic standoff used with compression AIMs.


Figure 20 Plastic Standoff Orientation

Step 5 Insert the connector on the AIM into the AIM connector on the system board. See Figure 18.


Note Be sure to press firmly on the AIM until the board seats onto the connector. The plastic standoff must snap into the hole in the AIM board. See Figure 18.


Step 6 Insert the screws from the accessory kit through the AIM into the metal standoffs. See Figure 18. Carefully tighten the screws with a Phillips screwdriver.

Step 7 Check that the AIM is installed correctly on the system board. See Figure 21.

Installing and Removing PVDMs

Cisco 2801 and Cisco 2811 routers hold up to two Cisco packet voice data modules, version 2 (PVDM2) to support enhanced versions of digital signal processors (DSPs). Cisco 2821 and Cisco 2851 routers hold up to three PVDM-IIs. If only one is PVDM installed, it must be located in the PVDM 0 connector.

Before you remove or install a PVDM, remove the chassis cover as described in the "Removing the Chassis Cover" section.


Note PVDM-II connectors in the Cisco 2800 series routers are not compatible with older PVDM versions.



Caution When you remove or install PVDMs, always wear an ESD-preventive wrist strap, and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the chassis.


Caution Handle PVDMs by the edges only. PVDMs are ESD-sensitive components and can be damaged by mishandling.

PVDM Location and Orientation

The PVDM connectors are located on the system board, and are identified as follows:

In Cisco 2801 and Cisco 2811 routers—PVDM 0 and PVDM 1

In Cisco 2821 and Cisco 2851 routers—PVDM 0, PVDM 1, and PVDM 2

Refer to Figure 8, Figure 9, Figure 10, and Figure 11 for PVDM locations.

PVDMs have a polarization notch on the mating edge to prevent incorrect insertion. Figure 32 shows the polarization notch on a PVDM.

Figure 32 PVDM Showing Polarization Notch

Removing a PVDM

To remove a PVDM from the system board, follow these steps:


Step 1 Locate the PVDM on the system board. See Figure 8, Figure 9, Figure 10, or Figure 11, depending on your router model, for the location of the PVDMs.

Step 2 Pull the PVDM retaining clips away from the PVDM at both ends, and then tilt the PVDM until it can be freely removed from the connector. See Figure 33.


Note PVDMs must be removed in order—PVDM 1 then PVDM 0 in Cisco 2801 and 2811 routers, and PVDM 2, then PVDM 1, then PVDM 0 in Cisco 2821 and 2851 routers.

Step 3 Place the PVDM in an antistatic bag to protect it from ESD damage.


Installing a PVDM

To install a PVDM, follow these steps.


Note If installing only one PVDM, install it in PVDM connector 0. If installing two PVDMs, install the second one in PVDM connector 1.



Step 1 Locate the PVDM connector on the system board. See Figure 8, Figure 9, Figure 10, or Figure 11, depending on your router model, for the location of the PVDM connectors.

Step 2 Orient the PVDM so that the polarization notch lines up with the polarization key on the connector. See Figure 32.

Step 3 Hold the PVDM at an angle and insert it carefully into the PVDM connector. Tilt the PVDM up to the vertical position so that the clips snap into place at both ends. See Figure 34.

Installing a Power Supply in a Cisco 2811 Router

Three types of power supplies are available for the Cisco 2811 router:

An AC-input power supply, driven by external AC power

A DC-input power supply, driven by external DC power

An inline power (ILP) supply, driven by external AC power. This supply provides power for the router and inline power for a complement of IP phones attached to the router.

The following sections describe how to install each type of power supply.

Removing the Existing Power Supply

Installing an AC-Input Power Supply

Installing a DC-Input Power Supply

Installing an ILP Supply

Removing the Existing Power Supply

To remove a power supply from a Cisco 2811 router, perform the following steps.


Caution Do not disconnect the flat ribbon cable (shown in Figure 37). The cable is of adequate length to perform the power supply replacement procedure. Removing the flat ribbon cable without the proper tools may cause damage to components in the router.


Step 1 Disconnect the power output cable connector (or connectors—see note below) from the power supply. Power supply connectors have a locking feature on the power supply end that you must release. Do not disconnect any power cables from the system board.


Note The AC-input power supply in a Cisco 2811 router uses only one power output cable. The DC-input power supply and the ILP supply each use two power output cables that must be disconnected. On the ILP supply, the ILP cable is also hooked to cable guides on the power supply and the chassis, so it must be both disconnected and unhooked from the power supply. See Figure 44.


Step 2 Remove the air duct by squeezing it gently at the bottom and lifting it straight up. See Figure 37. Note that there are four snaps on the air duct, two on each side. By squeezing the air duct, the snaps are released from the sheet metal retainers in the chassis that capture them.
