4.1 Guidelines and Limitations for Attaching Equipment

This section discusses a few things you need to keep in mind about the types of
devices you can attach to a ServSwitch™ Brand Fiber KVM Extender II or II-SM, in
addition to those described in Chapter 3.

4.1.1 CPU

The Extender supports IBM

PC compatible computer CPUs. A CPU must have

these kinds of interfaces to work properly with the Extender:

• Video: VGA compatible (DOS mode, VGA, SVGA, XGA, or SXGA), outputting

resolutions and refresh rates such as:

– 1280 x 1024 at up to 72 Hz;

– 1152 x 864 or 1024 x 768 at up to 75 Hz; or

– 800 x 600 or lower at 85 Hz.

• Keyboard: IBM PS/2 style (6-pin mini-DIN). (With a keyboard-port adapter, will

also support CPUs with PC/AT

[5-pin DIN] keyboard ports.)

• Mouse: IBM PS/2 style (6-pin mini-DIN).

4.1.2 M

ONITOR

Any monitor you attach to the Extender needs to be able to display a VGA
compatible video signal (VGA, SVGA, XGA, or SXGA) at the resolution and refresh
rate that your CPU is outputting it (see Section 4.1.1). If you use a Plug and Play or
DDC monitor (at either the local or remote station), you’ll have to configure its
video settings manually, because the Extender can’t carry the DDC signals or the
Plug and Play identification/negotiation signaling. When you do this, make sure to
choose only those settings that your monitor can support (refer to the monitor’s
manual). Configuring video incorrectly, especially if you select refresh rates that
are too high for the monitor to display, could damage or destroy the monitor.

4.1.3 K

EYBOARD AND

OUSE

The Extender’s keyboard and mouse interfaces are standard PS/2 type interfaces,
so you can attach just about any standard PS/2 compatible keyboard and mouse to
the Extender. Do not attach serial mice or bus mice to the Extender; they will not
work. You can attach a PC/AT style keyboard with a 5-pin DIN connector to the
Extender by using a keyboard adapter, available separately as product code FA211.
