Maintaining Your AccessPro 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 in your PC system manual.

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 4-2, with the DRAM SIMMs toward you.

Step 6 Locate the system-code SIMMs on the system card (see Figure 4-3).

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

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

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

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 directions provided by the manufacturer and turn on the power.

Changing Your Primary-Memory DRAM SIMMs

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

Table 4-3 lists approved 70-nanosecond (ns) DRAM SIMMs for the AccessPro card.

Table 4-3 : Approved DRAM SIMMs

4-MB Upgrade (1 MB x 36, 70-ns DRAM SIMMs)		16-MB Upgrade (4 MB x 36, 70-ns DRAM SIMMs)
Manufacturer	Part Number	Manufacturer	Part Number
Micron	MT9D136M-7	Mitsubishi	MH4M36ANXJ-7
NEC	MC421000A36BE-70	--	--

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. This expansion 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 4-4.

Table 4-4 : Feature Set Memory Requirements

Feature Set	Small Networks	Large Networks
IP only	2 MB	2 to 18 MB
IP with IBM Protocols	2 MB	2 to 18 MB
IP/IPX only	2 MB	2 to 18 MB
IP/IPX with IBM Protocols	2 MB	2 to 18 MB
Desktop	4 MB	6 to 18 MB
Desktop with IBM Protocols	4 MB	2 to 18 MB
Enterprise	6 MB	6 to 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 in your PC system manual.

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 4-2, with the DRAM SIMMs toward you.

Step 6 Locate the DRAM SIMM socket on the AccessPro card
(see Figure 4-3).

Step 7 Remove the existing DRAM SIMMs (if any) by pulling outward on the connectors to unlatch them. The connector holds the SIMMs tightly; take care not to break the holders on the SIMM connector (Figure 4-5).

Step 8 Using the orientation shown in Figure 4-3, position the SIMM so that the polarization notch is located at the right end of the SIMM socket (see Figure 4-5).

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 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 directions provided by the manufacturer and turn on the power.
