10.3.8 Replacement of LSLS Card

Pull the spring clip under the LSLS card and pull the card part way towards you
using the front handle. Tilt the top of the card away from the side of the cabinet,
lining up a notch on the card with the projection on the card holder, then pull the
card right out.
Replace with the new LSLS card by reversing the above procedure.
Note that LSLS 3 is reverse orientation; the spring clip is on top.

10.3.9 Replacement of I/O Card

The controller should be powered down before disconnecting any RJ45 connector.
I/O cards are situated on the back panel of the controller cabinet. Disconnect the
cables which are held in place with two screws each, then the serial cables and the
six mounting screws. Remove the card and replace with the new one. Reverse the
procedure to connect the new card.
10.3.10 Replacement of Intelligent Detector Backplane Card
The controller should be powered down before disconnecting any RJ45 connector.
The Detector Backplane card(s) is/are situated at the rear of the rack.
Generally speaking, only the Intelligent Detector Backplane card will need
replacing, although the replacement kit includes the passive Detector Backplane.
They are supplied together to protect delicate components and connections.
Remove the three nuts holding the card in place and pull away from the passive
backplane. Replace with the new card and tighten the nuts.
Reassemble and return the kit including the defective card to Siemens Poole.

10.3.11 Replacement of the Manual Panel Card

First unplug the cable connecting the panel to the CPU Card.
The panel is retained by a number of screws to the main cabinet assembly.
(Mounting methods may vary in different cabinets).
