2. Installation
Making Power Connections
b (Optional) Facing the front of the NV6257, install the redundant PS6000 power supply
modules in slots PS 2 and PS 4, as shown in Figure 2-4.

9 Facing the rear of the router, connect the ground lug to ground using a copper wire from 14 to
6 AWG. The ground lug is located in the lower, right-hand corner.
Connecting One NV6257 to Two Routers
When two routers are connected to one NV6257 power supply, different PS6000 power supply
module slots (see Figure 2-4) provide power to one or the other of the two routers (Router 1 and
Router 2), as follows:
To connect power to two routers from a single NV6257, two power supply cables (WC0085) are
required, provided by NVISION.
To make monitor connections between one NV6257 and two NV7512 routers, you will need to cre-
ate a “Y” cable. The “Y” cable has one central cable that branches into two cables, enabling one
source to be connected to two destinations. For instructions, see
Creating a “Y” Cable on page 40.
How to connect a single NV6257 to two router frames
1 Locate the power cords, PS6000 power supply modules, and cables supplied by NVISION.
2 If not already removed, remove all PS6000 power supply modules.
3 Create a “Y” cable. For instructions, see
Creating a “Y” Cable on page 40.
4 Facing the rear of the NV6257, using one of the two power supply cables (WC0085), connect
one end of the cable to ‘Output Power 2’, as shown in Figure 2-2 on page 36.

Caution Make power connections between the router and NV6257 before connecting the
NV6257 to an AC power source. Insert PS6000 power supply modules after con-
necting the NV6257 to an AC power source.
