SERVSWITCH™ AFFINITY

Keyboard

Use this field to assign one of the following keyboard modes or serial data rates:

• PC1: PC mode 1. Appropriate for most IBM compatible PCs that do not use

mode 2 or USB; in particular, several PS/2 models.

• PC2: PC mode 2. Appropriate for the vast majority of older IBM compatible

PCs.

NOTE

Most PCs are PC2, so you probably don’t need to change the setting.

Some IBM PCs can be either PC1 or PC2; for these PCs, there are two

ways to find out the correct mode:

If the computer you’re configuring is currently ON: If you can’t get

proper keyboard communication with the computer using the current

setting, try the other.

If the computer you’re configuring is currently OFF: Boot the

computer and type in a few keystrokes; the correct mode will be

autodetected, and if you still have the “Configure Computer” page

displayed, the correct setting will automatically appear in this field.

• PC3: PC mode 3. Appropriate for most non-USB UNIX workstations and

servers, including IBM RS/6000, SGI, HP 700 or 9000 series, Compaq

Alpha

etc.

• USB-PC: Appropriate for IBM compatible PCs with USB keyboards. (If you

choose this keyboard setting, the mouse field goes blank and can’t be

selected.)

NOTE

For an Apple computer with a legacy ADB keyboard and mouse, choose

PC3. For an Apple computer with a USB keyboard and mouse, choose

PC3 or USB-PC—either setting will work.

• USB-Sun: Appropriate for Sun computers with USB keyboards. (If you choose

this keyboard setting, the mouse field goes blank and can’t be selected.)

• Sun: Appropriate for Sun computers with legacy (8-pin mini-DIN) keyboards.

(If you choose this keyboard mode, you also force the Sun mouse type.)

• Serial 9600,N,8,1, etc.: If you’ve attached a serial device rather than a CPU to

the Affinity, select the serial setting that matches the best data rate that both

the Affinity and the device support: 9600, 4800, 2400, 1200, 600, 300, 110, or

50 bps. (Data format is fixed at 8 data bits, no parity, and 1 stop bit.) In the

example shown in Figure 4-5 on the next page, the “Computer 1” port has

already been set to be a 9600-bps serial port, and the “Computer 2” port is

about to be.

If you choose one of the serial settings in the keyboard field, the mouse field

goes blank and can’t be selected.
