The shelf managers support redundant operation with automatic switchover. If both shelf
managers are operating normally, one acts as the active shelf manager and the other as
the standby. Usually the primary shelf manager would be the active shelf manager and
the secondary shelf manager would be the standby. The shelf managers monitor each
other and either can trigger a switchover if necessary. The active shelf manager performs
all shelf manager functions. If the active shelf manager fails or is removed, the standby
shelf manager takes over all shelf manager functions. If one shelf manager fails or is
removed the other will operate independently and the chassis will continue to function
normally.
The shelf managers control chassis power allocation, monitor chassis operating
parameters, monitor and control chassis cooling, and can signal alarms if the chassis
encounters problems. All FortiGate-5000 boards installed in the chassis communicate
with the shelf managers.
The shelf managers are factory installed. In most cases users do not have to install or
configure the shelf managers.
Each shelf manager has two ethernet interfaces (CH0 and CH1). Both channels connect
to the chassis backplane.
•
When the Ethernet channel selector button is pushed in (recessed) CH0 connects to
the backplane.
•
When the Ethernet channel selector button is pulled out you can use the front panel
Ethernet connector to connect to CH0.
Each shelf manager also has an RS-232 serial port for connecting to the shelf manager
console CLI.
The shelf managers detect alarm conditions and communicate alarm signals to the
FortiGate-5140B shelf alarm module.
The shelf managers are hot swappable. You remove a shelf manager by loosening the
retention screw that positions the hot swap actuator. This disengages the hot swap
switch and puts the shelf manager into hot swap mode. The hot swap LED starts blinking
blue. When the hot swap LED turns solid blue you can completely loosen both retention
screws and remove the shelf manager from the chassis.
