1.4.2.5.4 Front Panel – Reset Button
The EM-7600-ES and EM-7600-ES-2GB provide a RESET button for resetting the board.
1.4.2.5.5 Front Panel – SWAP Button
The EM-7600-ES and EM-7600-ES-2GB provide a SWAP button for hot swapping the module
during operation. Before removing a module, users should first press the SWAP button. The module
will then prepare for a hot-swap and the system operation indicator (RUN) will turn yellow and
blink at 8 Hz. When the RUN indicator is off, the card is powered off and can be removed.
ES4710BD 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 ES4710BD 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.
