3. Using the appropriate tool, loosen the chassis retention screws on each side of the
PEM.
4. Open the ejector latches. This will signal the switch to deactivate the hot swap
signal. Watch for the Blue LED to go solid and steady, signalling that it is ready to
remove.
5. Open the ejector handles completely. You will feel the PEM disconnect from the
backplane.
6. Pull the module straight out from the rail guides, about 3 inches.
7. With the PEM in place and before removing the terminal block lug cover, screw a
standoff/lockout screw extension onto the retaining screws located on each side of
the PEM. Align the threaded end of the standoff/lockout screw extension with the
screw holes on each side of the shelf and securely tighten to lock the PEM
approximately 2 inches out of the shelf.
8. Using the appropriate tool, carefully remove the terminal block cover (plastic
covering) over the terminal block. The terminal block cover is attached to the
terminal block by two tabs with slots in the cover that insert into embossments in
the terminal block wall. To remove the cover, press the upper wall of the terminal
block wall downward and slip a flat-bladed screwdriver between the cover and the
terminal block wall and pry the cover tab up to relieve it from the embossment in
the terminal block wall. Once the upper cover tab is free from the terminal block
embossment, the cover should rotate downward and free itself from the lower
embossment.
9. Confirm that there is no power to the PEM lug bolts. Using a multimeter, measure
between the two lugs and then measure between the chassis ground and each lug.
If the DC potential is 3.0VDC or less, then power is not present.
If the multimeter indicates there is still power present and power cannot be removed from
the terminals, the entire shelf must be powered down to perform the PEM replacement.
