Power Supply Redundancy
Power supplies installed in the same OS-BPS chassis may operate in a redundant or backup configuration
by sharing the same electrical load with another power supply.
Hot Swapping
OS-BPS power supplies are hot swappable. If redundant power supplies are operating in the chassis, a
power supply can be removed or replaced without adversely affecting normal operation. New power
supplies may be inserted in empty power supply slots at any time.
Considerations if OS-BPS is the Only Power Source In a Stack
If the primary power supply fails on any switch connected to the OS-BPS, leaving the OS-BPS as the
switch's only power source, it is recommended that the primary power supply is replaced on the switch as
soon as possible.
If the primary power supply fails on any PoE-enabled switch connected to the OS-BPS and the switch
must be powered down, the PoE power must first be disabled on the switch using the lanpower stop CLI
command before disconnecting the DB25 connector between the OS-BPS and the switch.
Chassis Status LEDs
The chassis provides a series of status LEDs located on the front panel. These LEDs offer basic status
information for hardware operation and port link and activity status.
