This chapter tells you how to install the ISA Sync board and its software in the CHALLENGE M system.
Before you begin to install the ISA Sync upgrade into your system, you should check that the upgrade kit is complete and the board DIP switch settings are correct.
The ISA Sync board upgrade kit should contain the following items, as shown in Figure 2-1:
The board ID DIP switch bank, on the bottom of the board (see Figure 1-1 and Figure 1-2), is factory set for ID 0 (all three switches in the closed or down position). If you are installing more than one ISA Sync board, ensure that each board has a different ID. You can install up to four ISA Sync boards in a CHALLENGE M system.
|Caution: Be sure to double-check if the board ID is correctly set before starting the installation.|
To install the ISA Sync hardware, you must shut down the system, remove the cover, install the board, replace the cover, and install the cables.
To shut down and power off the system, follow these steps:
Open the front cover.
Press and release the power switch on the front of the system to shut down the software and power off the system.
The system powers off automatically.
Disconnect the power cable from the back of the system.
To remove the cover, follow these steps:
Remove the front bezel.
Press down on the tabs on each side of the bezel, as shown in Figure 2-2.
Pull the bezel down and away from the chassis.
Remove the top cover.
Press up on the tabs on each side of the drive openings and pull up on the cover.
Rotate the cover back and away from the chassis, as shown in Figure 2-3.
To install the ISA Sync board, follow these steps:
|Caution: If you have a non-X.21 board, ensure that resistor packs are not present at locations RP15 and RP17; see Figure 1-3 as required.|
Ground yourself to a metal part of the CHALLENGE M chassis.
|Caution: The ISA Sync board is extremely sensitive to static electricity; you must wear the wrist strap while installing it. The wrist strap prevents the flow of static electricity, which could damage the board.|
Put the wrist strap over your wrist, making sure it is tight against your arm.
Attach its alligator clip to a metal part of the CHALLENGE M chassis.
Move the system or position yourself so that you are facing the ISA slots.
The ISA slots are located on the left side of the system, behind the internal fan, as shown in Figure 2-4.
Open the metal panel located in front of the ISA slots by pulling up on the door and lowering it, as shown in Figure 2-5.
Remove the small cover over the slot in the back of the system in which you are installing the ISA Sync board.
Remove the screw that attaches the cover to the system. The screw is located inside the system on the outer end of the cover.
Install the board(s).
|Caution: If you are installing more than one ISA Sync board, ensure that each board has a different ID (see Figure 1-1 and Figure 1-2).|
Align the right side of the board with the metal grooves on the right.
Align the connector on the left side of the board with the connector opening on the left. Push the board into the slot until the connector on the back of the board is securely connected to the port on the backplane, as shown in Figure 2-6.
|Note: You may install the ISA Sync board into any available ISA slot. If you have multiple ISA Sync boards (up to four), you can put any board into any slot. The slot location or order does not matter.|
Insert and tighten the screw that holds the board to the chassis.
The screw opening is located on the metal bracket on the upper left side of the board.
Tip the metal panel up until it snaps into place, as shown in Figure 2-7.
To replace the cover, follow these steps:
Place the prongs on the underside of the cover into the slots under the top ridge of the backplane of the chassis, as shown in Figure 2-8.
Lower the cover onto the chassis until it snaps into place.
Replace the front bezel.
Place the tabs on the bottom of the bezel in the grooves in the front of the chassis, as shown in Figure 2-9.
Tilt the bezel up until it snaps into place.
Reconnect the power cable to the connector on the back of the system.
You are finished installing the ISA Sync board and are ready to attach the cables.
Follow the procedure in this section to install the ISA Sync board software from the distribution media onto your system.
|Caution: The ISA Sync upgrade requires IRIX version 5.3 for proper operation. This version of the ISA software is not compatible with IRIX 5.2. If you attempt to load this new version of the ISA software with IRIX 5.2, the system crashes when you try to boot the system.|
In addition, if you have an earlier version of the ISA software (running on IRIX 5.2), be sure to remove that version of the software before installing IRIX 5.3. Use the “remove” option from the inst program or the versions remove command to delete the necessary subsystems.
Power on your system, open a shell, and become superuser.
Insert the ISA Sync board CD-ROM and use inst to install the software. For example,
inst -f /CDROM/dist
Rebuild the kernel by entering the following command at the shell prompt as superuser:
This command announces the presence or absence of all optional boards in the system as follows:
exprobe spaced vc adapter n vc, adapter n exprobe space
The variable n indicates the ISA bus or adapter (board) number.
Reboot the system and continue by creating the configuration files, as described in Chapter 3, “Configuring Software for the ISA Sync Board.”
All utilities are installed in the directory /opt/vcom/bin.
Power on the system. At the system shell prompt, type hinv. You should see a display similar to the following:
ISA Synchronous Communications Board 0
The hinv command does not recognize the ISA Sync board until the drivers from the ISA Sync board CD-ROM have been loaded.
