5 Remove the front door by turning the retaining screws counter clockwise, opening the door, and
lifting it free of the hinges.
6 If the router was shipped with the circuit boards and fan tray in the frame, consider removing
them to make the frame lighter for installation. If removing circuit boards, be sure to note which
card was installed in which slot for later reinstallation.
7 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.
8 If removed, reinstall the fan tray in the fan slot at the top of the router. The tray is inserted right-
side up.
9 If removed, reinstall circuit boards. Be sure to install them in the correct location. For installa-
tion instructions, see
10 Reinstall the front door.
Making Power Connections
The power supply for the NV8256-Plus router is mounted externally in a separate frame, the
NV6257. The NV6257 uses the PS6000 power supply module. The NV8256-Plus requires a mini-
mum of four PS6000 power supply modules (plus four optional modules for redundancy).
The connectors and cables used to connect the router to the NV6257 are provided by Miranda, as
follows:
• Two, NV8256-Plus power supply cables (WC0085-00)
• One, NV8256-Plus monitor cable (WC0046-00)
The NV8256-Plus has a ground lug on the back of the router. Whether to ground or not is optional
and failure to connect the ground does not affect normal operation. However, grounding helps pro-
tect you and your equipment in case of a power anomaly such as a lightning strike.
Power Supply Monitor and Alarms Connections
The NV6257 has two DB25 connections, located on the rear. One connection, labeled ‘Power Sup-
ply Monitor’ carries alarm and temperature signals to the router. This connection is connected at
the same time the power connections are made. The other connection, labeled ‘Alarms’ presents
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.
