Power Backup and Power
Redundancy Connection
96xxG has two options for ensuring continuous power supply:
Power Redundancy
Power Backup
8.1 Power Redundancy
Microsemi 's power redundancy mode is available in 96xxG Midspan
series. This mode enables internal power supply backup for two
Midspans connected to each other. This mode provides seamless failover
between two Midspans. If one of the two Midspans' internal power
supplies fails, failure is detected automatically and working power supply
provides power to Midspan. Both Midspans are ensured continuous
uptime and all active ports continue to operate without any effect on
connected powered devices.
Power redundancy mode is available in the following midspans:
PD-9612G/ACDC/M
PD-9606G/ACDC/M
Note
: When using power redundancy option, connect together only units
that share the same power supply:
1Kw power supply units
o
PD-9612G/ACDC/M
o
PD-9606G/ACDC/M
WARNING:
When connecting power redundancy connectors, make sure AC power in
both
Midspans is disconnected from AC mains!
8.2 Power Backup
In case one of Midspans' power supplies fails, unit maintains full
functionality by using an optional backup power supply.
