Installing Backplane Boards
5
Warning – The procedures in this chapter must only be undertaken by
trained engineers.
Warning – You must disconnect the power supply befor e installing boards
into the pr ocessor module.
A number of boards can be connected to the rear of the processor module. Along
the top edge of the module backplane are connectors for up to 8 switch cards. Be-
low these are another 5 slots; 4 are used for the module SCSI cards, and one (the
larger one) for the module control card.
Blanking plates must be fitted over unused backplane slots to ensure correct cool-
ing and compliance with RFI regulations.
Installation
The installation procedure for all backplane cards is similar. Note however that
SCSI cards are normally installed during the module’s manufacture and are not
readily removed.
Remove the blanking plate from the rear of the module by removing the screws
at each end. In some case, particularly when removing boards, it is useful to re-
move the covers from the neighbouring card slots.
