Step 4
Connect the positive and negative power cables into the power supplies using a number 2 Phillips
screwdriver.
Note The DC power cables may use AWG #10 to AWG #12 wire.
Step 5 Replace the safety cover over the power terminals.
Step 6 Connect the other end of the power cables to an DC-power input source. If both power supplies will be
used, make sure they are on different circuits.
Step 7 Turn on the power from the power source. The DC supply does not have an on/off switch.
Step 8 Verify power supply operation by looking at the front panel power supply LEDs:
• The PS1 or PS2 LED is green when the power supply is functioning normally.
• The PS1 or PS2 LED is red when the power supply is not functioning normally.
• The PS1 or PS2 LED is off when the power supply is not connected to a power source.
From the system console, enter the show power command to display the power supply and system status.
For more information on this command, see the command reference publication for your software
release.
If the LEDs or show power command indicate a power or other system problem, see Chapter 5,
“Troubleshooting the Installation,” for troubleshooting information.
