2. Introduction
Power Supply
Figure 2-2 shows the flow of signals in the NV8288-Plus when connected to another NV8288-Plus
router.

Power Supply
The power supply for the NV8288 and the NV8288-Plus is an external, separate frame. There are
two external power frames available: the NV6257
1
and the NV8000. Each power supply frame
uses a specific power supply module that supplies power to the router frame.
Each external power frame uses the following module:
• The NV6257 uses the PS6000 power supply module and can house up to 8 modules.
• The NV8000 uses the PS8010 power supply module and can house up to 4 modules.
The power supply modules differ in the amount of power produced: The PS6000 produces 660
Watts while the PS8010 produces 875 Watts. Because the PS8010 produces a greater amount of
power, fewer modules are needed, reducing the frame size amount of facility space required.
The number of power supply modules required depends on which and how many routers are being
used. For redundancy, additional (optional) power supply modules can be installed.
The minimum number of required power supply modules are as follows:
