Check for the following before connecting the power cords:
Make sure that all of the power supplies are seated firmly, with
the captive screws tightened.
Make sure that all of the ON/OFF switches on the power
supplies are OFF.
If you are using multiple power supplies to ensure fault
tolerance, make sure that there is a dedicated power circuit
available for each supply. The separate power sources help
ensure operation when the power source itself fails.
To connect the power supplies:
1. Plug the power cord into each power supply.
2. Plug the power cord into an AC outlet.
To power on the system:
1. Check all power connections.
2. Turn on each power supply by switching on the power
switches on each supply.
As the system powers on:
The supervisor module displays switch information on a
31-character LED front panel
Port LEDs will cycle from yellow to normal operating status as
the system continues through its power-on diagnostics, if the
modules operate properly.
Refer to Table 2-7 for an explanation of the front panel LEDs:
* Note: Refer to the section "Interpreting Front Panel LED
Displays" in Chapter 17, Monitoring the Cajun Switch, in
the Cajun P550R/P880/P882 Switch User Guide for
more detailed information about the front panel LEDs.
