Troubleshooting
If the power supply module fails or is not working properly, isolate and correct the
problem by determining the answers to the following questions and then taking the
indicated action:
1. Is the Power ON LED lit?
YES
Note:
In a dual power supply chassis, make sure that one power supply’s
configuration switch is set to Master and the second set to Slave. See
“Configuring two power supplies in one chassis,” page 6.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
If the power ON LED is not lit, check the following:
2. Is the power supply’s ON/OFF switch in the ON position? If yes, and still no
activity, slide the switch to the OFF position and move to step “3.”
3. Is the power supply module properly connected to the external power source?
a.
See “Connecting external power,” page 8. If yes, move to step “b.”
b.
Is the disconnect device for the external power source properly installed and
in the ON position?
- If not, set it to ON and then slide the power supply ON/OFF switch to the
ON position. If still no activity, slide the power supply switch to the OFF
position and move to step “c.”
c.
Verify that the external power source voltage and current are at the proper
levels. If not, correct the problem; if they are, move to step “4.”
4. Check that the power supply’s fuse is not blown? See “Replacing the fuse,”
on page 11. If it is not: Contact Technical Support: US/Canada: 1-800-260-
1312, International: 00-1-952-941-7600.
