Chapter 11: Troubleshooting
210 Section II: Installing the Chassis
software version on the control card, refer to “Using Local
Management to Verify the Chassis” on page 204 and “AlliedWare
Plus Software Releases for the Hardware Components” on
page 77.
The problem may be with one of the two power supply interfaces
(opto-couplers) on the rear panel of the chassis. For
troubleshooting suggestions, refer to “Power Supply Interfaces
(Opto-couplers)” on page 220.
The power supply interfaces are not hot swappable and should only
be serviced by an authorized service technician.
