Power Modules
The power modules of 3Com 6000 Routers can work in either single-power or
dual-power mode. In dual-power mode, the two Power Modules function in a
redundant; loading sharing mode. The input interruption or failure of a PWR does
not affect the operation of another PWR, and this operating PWR will provide all
the power required by the system.
Power Modules controls functions of overcurrent protection and overvoltage
protection.You can connect the PWR to the backplane by inserting it from the rear
of router chassis. It is hot swappable and its switchover will not affect the ongoing
system operation.
If you want to install a 6000 Router in a communication equipment room, you
should make sure that the power distribution cabinet can provide the lightning
protection box or arrester against the current of 20KA and above.
WARNING: Do not connect the AC power cord while inserting or removing a
card.
ON/OFF switch should be set to OFF while inserting or removing.
