CHAPTER 4: Configuring the ACS236A
4. Configuring the ACS236A
This chapter describes how to configure the Sun model of the ServSwitch™ Brand
Fiber KVM Extender (ACS236A). If your Extender is the PC model (ACS235A),
see Chapter 3.
4.1 Setting the Jumpers in the Local Module (Optional)
There are four user-settable jumpers inside the Local Module of the ServSwitch
Brand Fiber KVM Extender. They control these options:
• How the Local Module handles video: VGA input to VGA output (default),
VGA input to legacy Sun output, or Sun input to either VGA or Sun output
(jumpers JP2 and JP10).
• Whether the Local Module uses automatic (default) or manual gain control
(jumper JP3).
• Whether the Local Module expects to transmit into 62.5/125-µm (default) or
50/125-µm fiber (jumper JP5).
If you need to set the unit for a non-default option, open the Local Module—being
sure to take all reasonable precautions against static electricity—by unscrewing the
upper part of its casing. (The jumper locations on the motherboard are shown in
Figure 4-1 on the next page.) Then set your desired jumpers as described in
Sections 4.1.1
, 4.1.2, and/or 4.1.3, and then close the unit back up.
