3.3.2 Inserting and removing modules
It is not necessary to remove power from the frame when inserting or removing system
modules as they have been designed so that they can be ‘hot-plugged’ with the system
powered.
The modules slide along guide rails in the frame and plug into connectors attached to the
motherboard, or rear connector assembly:
•
Ensure that the module is located in the correct position
•
Slide the card along the guide rail of the required slot, gently pushing it fully home
until it marries up with the connector
•
Connect ribbon cables, where applicable, by pushing them home until the catches
locate
If a card has a board reset switch, it is wise to exercise this after plugging a board in with the
power on. To remove a module, lift up the card ejector on the module and gently pull the
card out
3.3.3 Fitting rear connector panels
The rackframe is supplied with rear connector panels and, where necessary, blanking plates.
In cases where a frame is being upgraded, to add more audio levels for example, it may be
necessary to fit new rear panels. To fit panels, or to later change the position of a module,
the procedure is as follows:
•
Locate the correct position on the frame and remove any blanking plates or
existing rear connector panels
