Installation of BC Supervisor
Ë ATTENTION:
THE COVER ON THE MULTISERV/FT SUBSYSTEM SHOULD BE REMOVED BY SERVICE PERSONNEL ONLY!
CAUTION: THE SUBSYSTEM HAS MORE THAN ONE POWER SUPPLY CORD. DISCONNECT 2 POWER SUPPLY CORDS BEFORE SERVICING TO AVOID ELECTRIC SHOCK.
Cubix provides a passive EISA compatible backplane in all MultiServ/FT Subsystems consisting of slots divided into groups, for a total of 16 slots. (A group consists of backplane slots electrically connected together.)
The groups are identified as "Group 1", "Group 2", etc.
When installing a Cubix EISA BC Series processor, the processor must be installed in an EISA master slot. Refer to Chapter 2 for master slot locations.
CAUTION: Always place the insulating barrier between the board to be removed and an adjacent board that has power on. (This insulating barrier is stored on the left side of the subsystem). Do NOT drop any tools or hardware into the processor section.
Installation/Replacement Instructions:
1. Remove the cover from the unit.
2. Turn off power to the group or groups to be serviced. Check group and slot power indicator lamps to be sure power is off to all slots in the groups to be serviced. Note: The group power indicators are located adjacent to each group switch. The slot indicators are located on the rear of the backplane, near the end bracket.
3. Disconnect the 40-pin hard disk drive ribbon cable from the top edge of the BC processor being replaced.
4. Disconnect the 34-pin floppy drive and 14-pin video/keyboard ribbon cables from the processor being replaced.
5. Disconnect the 3-pin and 5-pin locking cables (mouse and BC control cables) from the processor being replaced.
! The release tab on the connector housing must be pressed when removing locking connector cables.
6. If replacing an existing BC Series processor, disengage the retaining screw from the BC end bracket and remove the BC board.
7. If adding a new BC Series processor, disengage the screw securing the blank end bracket from the rear I/O panel in line with the vacant slot desired. Remove the end bracket.
8. Install one Cubix BC Series bus controller board into each group as desired. Secure each board with the screw located in the end bracket.
9. Connect the cables between the BC Series board and the multiplexor panel. The multiplexor panel connectors are documented in Appendix C of this manual; the BC Series connectors are defined in the documentation provided with the BC Series processor.
10. Verify that a monitor and keyboard are connected to the MultiServ/FT Subsystem. Turn on the power to the group.
11. Run the BIOS setup program on each BC Series processor. Refer to the setup documentation provided with the BC board.
