Troubleshooting the CSS Power Supply
A CSS 11506 can contain a maximum of three power supplies, but it requires two
functioning power supplies to guarantee service. Figure C-1 shows the location of
the power supplies.
Figure C-1 Location of the CSS 11506 Power Supplies
If the CSS 11506 contains less than three power supplies, a power supply is
powered off, or a power supply module failed, the CSS displays the following
messages:
CHMGR: Missing backup power supply.
CHMGR: Cannot locate power supply: PSnumber.
The PSnumber variable indicates which power supply cannot be found or has
failed.
When this message occurs, view the LEDs on the power supply. Figure C-2 shows
the AC power supply LEDs. These LEDs indicate the power status of the supply.
1 Power supply 1 3 Power supply 3
2 Power supply 2
