SECTION 7 - MAINTENANCE INFORMATION
CAUTION
THE BACKPLANE CONNECTORS ARE NOT PROVIDED WITH LOCATING GUIDES. IN THE FOLLOWING
PROCEDURE IS IT IMPORTANT THAT THE DAUGHTERCARD CONNECTOR IS ALIGNED WITH THE
BACKPLANE CONNECTOR BEFORE THE MODULE IS PUSHED FULLY HOME.
REFITTING THE Daughtercard
Insert the daughtercard into the appropriate slot. Slowly push the daughtercard into the backplane, but DO NOT
force the daughtercard into the backplane connector. It may take a certain amount of manoeuvring to locate the
daughtercard connector into the backplane connector. If the daughtercard connector does not locate correctly into
the backplane connector a certain amount of freeplay allows the daughtercard to be manoeuvred up and down and
from side to side until the connectors are aligned. Once the connectors are correctly aligned push the daughtercard
home.
Repeat this procedure for all removed daughtercards.
Refit the front panels, and loosely secure with the securing screws, but DO NOT tighten any screws until everything
is refitted.
(Note: There is 0.5 mm approx of “free play” on the Daughtercard between the back plane and the front panel.When
tightening the front panel screws the inserted daughtercard could be pulled out about 0.5 mm. This does not effect
the interconnection on the backplane)
Refit the ejector handle if this was removed during the daughtercard 1 and 2 removal procedure.
Tighten all screws.
RELAY REPLACEMENT
NOTE
This is a very high density design, as a consequence removal of the relays can be awkward since there is
no access to the relay sides to grip them during de-soldering. Further guidance on removal can be obtained
on our Knowledgebase http://wiki.pickeringtest.net/ReRelays or search the Knowledgebase for
“Replacing Relays”.
