Removing PM Cards
To properly remove a PM card from the LE2425A Managed Fiber Switch,
follow the 3 steps below.
Step 1.
Remove chassis cover
See procedures in Section 3.5.1 above.
Caution: Be sure the power cord is unplugged.
Step 2.
Remove retaining screws placed on top for the PM and Face Plate
On the top of the daughter module there are six
retaining screws for each PM card. These screws are
used to secure a PM card in position (see Figure
3.5.3a). Remove the three standoffs holding the
Granddaughter board with the chassis. The screen
faceplate screws out from the inside front of the
chassis cover by loosening the 4 screws and bracket
while holding it down firmly.

Step 3.
Remove PM Card
Carefully and gently pull
out the daughter board from the latching
connectors, using both hands, gripping the
board near the latch-up connectors as shown
in Fig. 3.5.3b . If the now empty slot is to
remain unused, be sure to install a PM-BLNK
face plate cover.
