Encryption The RPU2 supports the Encryption Accelerator daughter card. This Accelerator Daughter optional add-on for the RPU2 uses hardware encryption to expedite IP

Card packet encryption and provides support for IPSec and DVPN.

The PSU Module The power supply system of the Router 6000 can work in either single-power or dual-power mode. In dual-power mode, the two power supply units (PSUs) function in redundancy or load sharing mode. That means, when a PSU fails or its power supply is disconnected, the other PSU can still work and supply all the power required by the system.

The PSUs supply 350W power and provide overcurrent and overvoltage protection. You can connect a PSU to the backplane by inserting it from the rear of the router chassis. It is hot swappable and its switchover does not affect the ongoing system operation.

When installing your router in a communications equipment room, ensure that the power distribution cabinet can provide a lightning protection box or arrester against the current of 20 KA and above.
