DCRS-7600 InstallManual
DCRS-7608 uses 2 +1 redundant power supplies, three power modules can act as
backups for each other. During normal operation, all three power modules each take one
third of the load. If one of the modules fails or is not present, the other two power modules
will supply power for the whole switch, and the corresponding POWER/Fail warning
indicator for the failed/missing module will illuminate, prompting the replacement of the
failed module. The warning indicator will turn off after the failed module is replaced or
recovers.
The DCRS-7608 power module is installed in the lower section of the chassis, and
connects to the power board of the switch. All the power modules attach to the chassis
with 2 screws, respectively. When replacing the power modules, the chassis need not to
be opened, just remove the 2 fastening screws to take out the power module requiring
replacement.
