Maintaining the AccessPro PC Card

System-Code SIMM Replacement

Following is the procedure for upgrading the system-code Flash memory:

Step 1 Turn OFF power but, to channel ESD voltages to ground, do not unplug the power cord.

Step 2 Remove the PC chassis cover, if it has not already been removed, following the instructions provided by the PC manufacturer.

Step 3 Attach an ESD-preventive wrist strap.

Step 4 Locate the AccessPro card in its ISA-bus slot if it has already been installed. Remove the screw that secures the card bracket to the PC chassis. If a daughter card is installed, remove the screw that secures the daughter card bracket to the PC chassis.

Step 5 Turn the card so it is oriented in the position shown in Figure 5-2, with the DRAM SIMMs toward you.

Step 6 Locate the system-code SIMMs on the system card. (See Figure 5-3.)

Step 7 Remove the existing system-code SIMMs (if any) by pulling outward on the connectors to unlatch them. The connectors holds the SIMMs tightly, so be careful not to break the holders on the SIMM connector. (See Figure 5-4.)

Caution To prevent damage, do not push on the center of the SIMMs. Handle each SIMM with care.

Step 8 Orienting the AccessPro card as shown in Figure 5-2, position the new SIMM so that the polarization notch is located at the right end of the SIMM socket. (See Figure 5-4.)

Caution To prevent damage, note that the Flash memory SIMMs have the components mounted on the rear side. Therefore, when you insert the SIMM, always use the polarization notch as a reference and not the position of the components on the SIMM.

Step 9 Insert the new SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45-degree angle to the AccessPro card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force or the connector could break.

Step 10 Insert the AccessPro card into its ISA slot on the PC motherboard. Carefully align the edge connector on the ISA slot, and use a rocking motion to seat the card in the proper position. Secure the card in the ISA slot with the bracket screw.

Step 11 Replace the cover of the PC following the documentation provided by the manufacturer and turn on the power.

Changing the Primary-Memory DRAM SIMMs

Depending on the level of system features you have chosen for your AccessPro card (IP Routing, IP/IPX Routing, Desktop, or Enterprise), the card may be shipped with additional primary-memory DRAM SIMMs. The DRAM SIMMs are in an ESD-protective bag within the shipping container.

After booting up, your system will indicate in the system banner the amount of primary memory it has. The following example shows a system with 2 MB (2048 KB) of primary memory. (The system does not display shared memory.)

If you use very large routing tables or many protocols, you might need to expand primary memory. Expanded primary memory might be necessary with configurations in which the AccessPro card is set up as a connection device between large external networks and your internal network.

The feature set you have chosen with your AccessPro card may require more than the standard 2 MB of DRAM. The memory requirements for the feature sets are listed in Table 5-3.

Table 5-3 : Feature Set Memory Requirements

Feature Set	Small Networks	Large Networks
IP Routing	2 MB	2--18 MB
IP Routing with IBM protocols	2 MB	2--18 MB
IP/IPX Routing	4 MB	4--18 MB
IP/IPX Routing with IBM protocols	4 MB	4--18 MB
Desktop	4 MB	6--18 MB
Desktop with IBM protocols	4 MB	2--18 MB
Enterprise	6 MB	6--18 MB
Enterprise	6 MB	6 to 18 MB

Tools and Equipment Required

The following tools and equipment are required to install DRAM SIMMs in your AccessPro card:

• Number 1 Phillips screwdriver
  

• ESD-preventive wrist strap with an installed alligator clip
  

• The appropriate DRAM SIMM for your AccessPro card
  

DRAM SIMM Installation

Following is the procedure for installing DRAM SIMMs:

Step 1 Turn OFF the system power but do not disconnect the power cord.

Step 2 Remove the PC chassis cover following the instructions provided by the PC manufacturer.

Step 3 Attach an ESD-preventive wrist strap to a ground point to prevent equipment damage.

Step 4 Locate the AccessPro card in its ISA-bus slot. Remove the screw that secures the card bracket to the PC chassis.

Step 5 Turn the card so it is oriented in the position shown in Figure 5-2, with the DRAM SIMMs toward you.

Step 6 Locate the DRAM SIMM socket on the AccessPro card. (See Figure 5-3.)

Step 7 Remove the existing DRAM SIMMs (if any) by pulling outward on the connectors to unlatch them. The connectors holds the SIMMs tightly; take care not to break the holders on the SIMM connectors (see Figure 5-5).

Step 8 Using the orientation shown in Figure 5-3, position the SIMM so that the polarization notch is located at the right end of the SIMM socket (see Figure 5-5).

Caution To prevent damage, do not push on the center of the SIMMs. Handle each SIMM with care.

Step 9 Insert the new DRAM SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45degree angle to the AccessPro card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force or the connector could break.

Step 10 Insert the AccessPro card into its ISA slot on the PC motherboard. Carefully align the edge connector on the ISA slot, and use a rocking motion to seat the card in the proper position. Secure the card in the ISA slot with the bracket screw.

Step 11 Replace the cover of the PC following the instructions provided by the manufacturer and turn on the power.

Recovering a Lost Password

If you lose your enable password, or can't remember it, you can recover it.

Systems running Cisco IOS Release 10.3(2) software or later use the enable secret password, which is encrypted, and therefore cannot be recovered. If you lose your enable secret password, you must configure a new one.

Following is the procedure for recovering a lost enable password and configuring a new enable secret password. Before beginning this procedure, you should have terminal emulation software running on your PC.

The password recovery procedure takes place in the following three steps:

1. Enter ROM monitor mode.
   

2. Configure a new enable secret password or recover a lost enable password.
   

3. Save the configuration changes you make to NVRAM.
   

Entering ROM Monitor Mode

Take the following steps to enter ROM monitor mode:

Step 1 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control (or to whatever settings the AccessPro card has set).

Step 2 Enter the command show version to display the existing configuration register value. Note this value for later use in Step 4 in the section "Saving Configuration Changes."

Step 3 If Break is disabled on the AccessPro card, reboot the PC. If Break is enabled, send a Break and then proceed to Step 4.

Step 4 Within 60 seconds of rebooting the PC, press the Break key. This causes the terminal to display the bootstrap program prompt (>).

Step 5 To reset the configuration register to boot from the boot ROMs and ignore NVRAM, enter the following command at the bootstrap prompt:
