While attaching the line connection card to the expansion card, one must make sure that the
connectors are plugged entirely and the line connection card fits firmly into the clicks on the
edge of the plastic cover. Cards that have not been fitted into the slots properly would cause
friction with the cards nearby while removing or replacing them, as well as they cause the
LEDs on the front face not to be seen from outside, because the LEDs would not coincide
with the dedicated holes on the front cover.
The connectors on the line connection cards have been included only in order to provide
facility for replacement of the card without detaching the cabling, in case protection circuits
on the card are damaged. While replacing the card, cables should not be detached from that
connector. In order to ensure this, while the connection is being made for the first time, the
expansion module should be placed on the rails and slid into the rack until a gap of 6-7 cm.
remains before it entirely fits into its place, as the cable is still loosely hanging down. The line
connection cable should be fixed on the back surface of the exchange while the expansion
module is at that position. The illustration below shows cross section of a card from the side,
which has been fitted into the slot correctly.
