The T1600 Core Router has two redundant, load-sharing power supplies, located at the
lower rear of the chassis in slots
The power supplies connect to the midplane, which distributes the different output
voltages produced by the power supplies to the T1600 router components, depending
on their voltage requirements. For each output voltage that the power supply provides,
it has either an active circuit breaker or an active current limiter.
NOTE: There are no passive fuses in the router that must be replaced.
Each power supply is cooled by its own internal cooling system. Power supplies are
hot-removable and hot-insertable.
The T1600 router supports these power supplies:
Three-input 240-A DC power supplies (Junos OS Release 8.5 and later)
Four-input 240-A DC power supplies (Junos OS Release 9.6 and later)
Three-phase delta AC power supply (Junos OS Release 10.0R2 and later)
Three-phase wye AC power supply (Junos OS Release 10.0R2 and later)
NOTE: Redundant power supplies must be the same model number.
