Removing ISI Boards

Note: If removing or replacing the single ISI board on the left side (looking from the front) of the midplane, card cage removal is not necessary. Ignore steps 3 through 5.

1Remove the CommPlete 4000 from rack enclosure (two people are needed). Follow the procedure “Disconnecting Cables and Removal from Enclosure” presented above. Summary: after powering down the unit and disconnecting all power and signal cables, employ two persons to remove its rack-mounting screws and lift the unit out of the rack.

2Remove the top cover from the CommPlete 4000 by removing the seven cover mounting screws located in the back of the CommPlete 4000. See figure 4-3.

3Remove the two chassis mounting screws from the card cage. See figure 4-4.

4Being careful to maintain slack in the power cables, lift the card cage up and over so

that it rests along side the chassis.

5Remove screws that secure the serial card to the chassis at the back of the CommPlete 4000 .

6Remove the serial card(s) from the midplane.

7To replace the serial card(s), verify the configuration of the cards. See the installation instructions in the serial card section(s) of this manual.

8Install the new serial card(s) by following steps 1-6 in reverse. That is,

a.Attach serial card(s) to midplane socket(s).

b.Secure serial card to rear of chassis with screw.

c.Re-install card cage (2 screws). Make sure the power cables are securelyattached.

d.Replace top cover (7 screws).

e.(Two people are needed.) Replace CommPlete 4000 into rack enclosure.

Note: If you are simply adding a hard drive and not replacing the existing hard drive, proceed to step 6.

3Disconnect the power and data cables from the back of the hard disk drive.

4Remove the three screws that secure the hard drive to the drive chassis. You must lift the card cage out of the chassis to gain access to the third screw.

5Remove the hard drive by sliding it up and out of the drive chassis.
