Figure 5-21 Removing an E1 Port Adapter
Step 4
Remove the jackscrews and washers and put them aside.
Step 5 Use a number 1 Phillips screwdriver to loosen and remove the four standoff screws. (See
Figure 5-21.) The port adapter is now held in place only by the plastic BTB connector.
Step 6 While avoiding contact with any traces or components on the board, insert your thumb and
forefinger under the extension behind the BTB connector and gently lift the adapter upward
to dislodge it from the MIP connector. If the port adapter resists, rock it very slightly from
side to side until it pulls free of the MIP connector.
Caution To prevent damage to the MIP, do not pry the port adapter out with a screwdriver or any
other tool. In particular, do not use the board stiffener for leverage.
Step 7 When the port adapter is completely disconnected from the MIP connector, tilt the back of
the port adapter up at about a 70-degree angle from vertical and slowly pull it up and out
(using the orientation shown in Figure 5-21) and away from the faceplate. The MIP cable
connector will pull out of the cutout in the faceplate.
Step 8 To reconfigure jumpers on the E1 port adapter, refer to the section Configuring Jumper J6
on the E1 Port Adapter earlier in this section. After you have set the jumpers, proceed to
the next section, “Replacing a Port Adapter.”
