4-PORT EXPANSION BOARD FOR SERVSWITCH™ AND SERVSWITCH™ ULTRA

15. Put the PCB-stack-plus-back-panel assembly back together with the Switch’s bottom

and front panels. (This can be very tricky. Hold the assembly at a 45° angle relative

to the front panel—this will make it much easier to realign the LEDs with the

corresponding holes in the front panel.)

16. Refasten the PCB stack to the bottom panel by screwing the screws that you

removed in step 5 back in.

17. Refasten the back panel to the bottom panel by screwing the screws that you

removed in step 4 back in.

Before putting the Switch’s top cover back on, test the unit as directed in steps 18

through 22.

18. Temporarily connect the Switch to a monitor, keyboard, and mouse, along with at

least one CPU for every PCB in the Switch. (On a Switch you have just expanded to

twelve ports, for example, one CPU should be attached to port 1, one CPU to port 5,

and one CPU to port 9.)

19. Plug the Switch back in and turn it ON. (If, using the configuration currently stored

in its NVRAM, the Switch won’t be able to switch to all of the test CPUs, you might

have to change the Switch’s “Maximum computers,” “Expansion width,” and

“Expansion units” values. Refer to Sections 5.2.3 through 5.2.5 of your ServSwitch

or ServSwitch Ultra manual.)

20. Turn ON the attached monitor and CPUs.

21. Make sure that the Switch’s front-panel pushbuttons, keyboard commands, and

overlay menus will still scan and switch between all of the CPUs from the front panel

as before. If the Switch does not respond properly, call Black Box for technical

support.

22. If the Switch seems to be working properly, turn OFF the Switch and all attached

test equipment. Unplug the Switch from utility power and disconnect it from the test

equipment.

23. Replace the Switch’s top cover.

24. Refasten the top cover by screwing the screws that you removed in step 2 back in.
