Making Power Connections
6 Remove the front door by turning the retaining screws counter clockwise, opening the door, and
lifting it free of the hinges.
7 If the router was shipped with the circuit boards and fan trays in the frame, consider removing
them to make the frame lighter for installation. If removing circuit boards, be sure to make a
note of which card was installed in which slot for later reinstallation.
8 Lift the frame into position and attach the router frame to the front of the rack with the appropri-
ate screws. Be sure to place screws in all frame mounting screw holes.
9 If removed, reinstall the fan trays in the fan slots at the top and bottom of the router. The tray is
inserted right-side up.
10 If removed, reinstall circuit boards. Be sure to install them in the correct location. For installa-
tion instructions, see Installing Active Cards on page 33.
11 Reinstall the front door.
Making Power Connections
The power supply for the NV8288 and the NV8288-Plus router is a separate external frame: either
the NV6257 or the NV8000. The NV6257 uses the PS6000 power supply module (660
Watts; the
NV8000 uses the PS8010 power supply module (875 Watts). For the NV6257, the number of power
supply modules installed in the power supply frame depends on the type of router and if two routers
are being connected together. For the NV8000, one power supply frame is required for each router
and each router requires two PS8010 power supply modules (plus two modules for redundancy).
For a list of how many power supply frames and modules are required, see
Power Supply on
page 6.
When you are connecting either the NV6257 or NV8000 to a router, and the power supply frame to
power, two types of connections are made between the router and the power supply frame: (1)
power and (2) monitoring. The specific cables to use depend on which router is being connected to
the power supply, and whether two routers are being connected together.
Caution Do not use the front door handle to lift the entire frame. Doing so may dam-
age the door.
Caution Handle all circuit boards with care. Be sure to use electrostatic discharge
(ESDI) protection and place the circuit boards in ESDI bags or on an ESDI
surface.
Caution An equipment jack or two people are required to lift and install the router
frame. The router frame is considered too heavy for one person to lift and
install in the rack.
