4.1Guidelines 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).

4.1.2MONITOR

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.

4.1.3KEYBOARD AND MOUSE

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.
