2.5.2 Removing an Expansion Backplane
Note
:
Before you remove an EXP, you must power down the ROC827,
disconnect
all
wiring from
all
modules, and remove the
entire
unit from the DIN rail. Once the entire ROC827 is free of the
DIN rail, you can detach an individual EXP.
To remove an EXP from an existing ROC827 base unit:
1.
Remove the right-hand end cap from the EXP as described in
Section 2.3.1, Removing and Replacing End Caps
.
2.
Remove the wire channel covers on either side of the EXP you want
to detach, as described in
Section 2.3.2, Removing and Installing
Wire Channel Covers
.
3.
Turn the ROC827 around so that the back of the unit faces you (as
shown in
Figure 2-6
).
Note
:
It may be useful to place the ROC827 face-down on a flat
surface with the EXP you want to detach hanging free of the
surface’s edge.
