Computer port connections to standard computers
Depending on the model, ServSwitch Duo IPC can be
directly
connected to
a maximum of either eight or sixteen computer systems. Using KVM cable
sets (part number: EHN408-00xx -
where x is the length: 05, 10 or 20 feet
),
each computer is connected to one of the numbered ports at the rear of the
ServSwitch Duo IPC.
Connecting to Sun computers and USB ports
.
Further computers may be connected, by linking other switching products using
a cascade arrangement (explained in the
Cascade connections
section).
To connect a computer
1 Ensure that power is disconnected from the ServSwitch Duo IPC and all
computers to be connected.
(Note: If it is not possible to switch off a computer prior to connection, then
a ‘Hot plug’ procedure is available – see the
Hot plugging and mouse
restoration
section for more details).
2 Connect the plugs at one end of a KVM cable set to the keyboard, video
and mouse sockets of the computer (for keyboard and mouse plug
conversion information – see
Appendix 3
).

3 Connect the plugs at the other end of the KVM cable set to the corresponding
sockets, of the required COMPUTER PORT at the rear of the ServSwitch Duo IPC.
Note: Not all of the computer ports need be used and not all connected
computers need to be switched on, ServSwitch Duo IPC can sense the
presence or absence of computers.
User port connections
There are two user ports available at the rear of the ServSwitch Duo IPC. Each
port consists of three sockets to accommodate: a keyboard, a video monitor and
a mouse.
Keyboard and mouse mode logging
The ServSwitch Duo IPC maintains a log of all keyboard and mouse mode and
resolution settings that are requested by each of the connected computers.
These settings are automatically restored to the shared keyboards and mice
of the user ports when the ServSwitch Duo IPC channels are switched, thus
ensuring maximum software compatibility. The keyboard num, caps and scroll
lock states are a visible example of this process.
Data Display Channel (DDC) considerations
DDC allows the ServSwitch Duo IPC to discover the capabilities of a user port
video monitor and transmit that information to the connected computers so that
they can moderate their video output to suit the monitor. DDC can only sample
one monitor, so if you are connecting monitors of different resolution/frequency
capabilities, it is important to ensure that the DCC feature samples the lesser of
the two monitors. Please see
Display Data Channel
for details.
To connect a user port
1 Ensure that power is disconnected from the ServSwitch Duo IPC and all
devices to be attached.
2 Connect the cables from your keyboard, video monitor and mouse to
the three sockets of the required USER PORT (1 or 2), at the rear of the
ServSwitch Duo IPC (for keyboard and mouse plug conversion information
– see
Appendix 3
).
Note: Between the two user ports, no commonality of keyboards, video
monitors or mice is required as all devices attached to each port are handled
individually. However, please note the DDC considerations above.
