Removing and Installing the AC or Dual DC Power Supply
Figure 5-46
Connecting the Power Connectors to the Main Board
Step 4
Reconnect the following power connectors to the main board: (See
Figure 5-46
.)
a.
2-pin +/–12V connectors
b.
6-pin connector
c.
4-jack harness
Step 5
Turn the router so that you face the rear panel, and then reinstall the three mounting screws. (See
Figure 5-39
for the AC power supply and
Figure 5-40
for the DC power supply.)
Step 6
Replace the router cover. (See the
“Removing and Installing the Router Chassis Cover” section on
page 5-13
.)
To connect the AC power supply, go to Step 8. To connect the DC power supply, go to Step 7.
Step 7
Connect the DC power supply in the following order:
a.
Insert the safety ground (green wire) into the terminal block ground connector and tighten the
locking screw. Ensure that no bare wire is exposed. (See
Figure 5-47
.)
b.
Insert the +48 VDC wire (white wire) into the terminal block positive connector (+) and tighten the
locking screw. Ensure that no bare wire is exposed. (See
Figure 5-47
.)
c.
Insert the –48 VDC wire (black wire) into the terminal block negative connector (–) and tighten the
locking screw. Ensure that no bare wire is exposed. (See
Figure 5-47
.)
Note
Verify that the power supply leads are secured with a cable tie on the DC power supply.
