To disconnect a cable from the Core/Network Module backplane, use the
P0741489 Extraction Tool provided in the rear of the module (behind the I/O
safety panel).
You must use the P0741489 Extraction Tool to disconnect cables
Follow the procedure below to avoid bending or breaking pins when
removing cable connectors from the backplane shrouds. Do not insert
the extraction tool unless the cable connector is locked into the shroud.
Do not force the extraction tool deeper than the detent on the cable
connector.
1 Grasp the cable connector by the strain relief tab.
2 Center the longer flat edge on the angled end of the tool between the
cable connector and the wall of the shroud on the right side of the cable
connector.
Note: If the straight end of the tool is notched, use that end if the
connector can be accessed straight-on. If you must angle the tool at all,
use the angled end.
3 Gently insert the extraction tool and gradually apply pressure while
gently rocking the cable connector up and down.
4 Stop applying pressure as soon as the detent of the cable connector comes
loose from the shroud.
5 Slowly remove the extraction tool and the cable connector.
CAUTION
from the backplane shrouds in the
NT5D21 Core/Network Module.
