Figure 7 -- USB Server Switch -- Rear Panel Connections, 4 Servers shown
STEP 3 -- Connecting CPUs
Connect a single SERVER to the USB ServerSwitch and verify its operation. Use
the cables that were provided with the USB ServerSwitch to attach the SERVER.
Connect the cables as shown in Figure 7.
Make certain that all servers are powered off when connecting them to the USB
ServerSwitch. It is important to note that some servers do not allow for keyboards
to be connected and disconnected during operation. This may cause them to halt.
1) A standard USB-A to USB-B cable from the Server's Mouse/Keyboard
connector to the USB ServerSwitch. Maximum length is 25 feet.
2) An HD15 male-to-male video cable from the Server graphics adapter to
the USB ServerSwitch.
Once this is complete, continue to connect the remaining SERVERs. Repeat these
steps until all of the devices are connected.
NOTE! CPUs can be connected to any port. It is not necessary to use Port 1
as the first connection, Port 2 as the second, etc.
STEP 4 -- Power Up Sequence
The power-up sequence is very important for proper monitor operation, especially
if using DDC2B-compatible monitors. In some cases (e.g., SGI Onyx 3xxx series,
others) you must completely reboot your server to start the video signals. After all
cables are connected and the system is ready for use:
(1) Turn the Video Monitors for User A and User B On.
(2) Turn the USB ServerSwitch unit On (power switch to 'I') if not already on.
Wait approximately one minute for the USBSS to start up completely.
(3) Start Up the Servers. USB enumeration should occur automatically
