•
AC power connects directly to the NV8144 frame and to the NV8140 frame. AC power con-
nects to the NV8300 power supply frame used for the other NV8500 routers. The NV8144
requires a 15A circuit for each connection. The NV8140 requires a 20A circuit for each con-
nection. The NV8300 requires a 20A circuit for each of its power supply modules in 110 VAC
environments. (There are 4 modules in each NV8300 power supply frame.)
In 220 VAC environments, a 10A circuit is required for NV8300 power supplies.
•
If you are installing an expanded NV8576-Plus (two frames), the frames must be located near
each other, side-by-side or back to back, so that you can make expansion connections
between the frames. The distance between the frames is limited by the length of expansion
cables (4 meters). See
Connecting the NV8576-Plus Frames
•
To ensure proper cooling, leave space for unrestricted air flow through the front of the
router, and a minimum of 6-inches of clearance at the rear where the cooling fans exhaust
warm air.
•
Allow space for cabling to the router’s I/O connectors.
To Rack Mount the Router
1 Temporarily place the router frame near the rack in which it is to be installed.
2 Remove the front door by turning its retaining screws counter clockwise, opening the door,
and lifting it free of its hinges.
Important: never use the front door handle to lift the frame.
3 The router was shipped with control cards, crosspoint cards, I/O cards, I/O backplanes, and
fan trays installed. Remove them to make the frame lighter for installation. If you do remove
the cards, be sure to note which card was installed in which slot for later reinstallation.
4 Lift the frame into position and attach the router frame to the front of the rack with the
appropriate screws. Be sure to place screws in all frame mounting screw holes.
Note: NV8576 frames are shipped with a rack-mounting kit, including a jack, a shelf for sup-
porting the frame while it is still not secured with screws, handles for lifting the frame into
place, and instructions for rack-mounting using the kit. An NV8576-Plus is also shipped with
the rack-mounting kit. An NV8280 frame is shipped with a handle for lifting it into place.
5 Reinstall the fan trays in the fan tray bays. The fan tray openings face the interior of the
router. In the NV8576 and NV8576-Plus frames, the openings of the upper fan tray face down
and the openings in the lower fan tray face up.
CAUTION
Handle all circuit boards with care. Be sure to use electrostatic discharge (ESD) protec-
tion and place the circuit boards in ESD bags or on an ESD surface. Do not stack boards
without ESD protection.
CAUTION
An equipment jack or two persons 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.
