Power
NV8500 series routers use power supply modules to power the router frames. Two power supply
models exist: the PS8100 (850 Watts) and the PS8300 (1350 Watts). The PS8100 is used by the
NV8144. The PS8300 is used by the NV8140, NV8280, NV8576, and NV8576-Plus. The PS8100
resides in a power supply bay of the NV8144. The PS8300 resides in a power supply bay of the
NV8140. For the larger routers, the PS8300 resides in an external NV8300 power supply frame.
The power supply frame holds up to 4 PS8300s.
Additional power supply modules can be installed as a backup, or secondary, source should the
primary module fail. All routers are fully operational using only the primary or only the backup
power supply module.
The router’s control card monitors power supply status. Power status information is sent to the
router control system and to the Miranda Router Configurator (MRC) in which alarms can be set
up to notify technicians. (See
Making Alarm Connections
on page 112. Refer also to the
Miranda
Router Configurator User’s Guide
.)

Power Requirements
Each router frame requires a different amount of power. Power requirements also depend, to a
lesser degree, on the number of input and output cards installed. Each power supply module
has been designed to meet the maximum power needs of a router frame.
The NV8144 uses the PS8100 module. A PS8100 can be installed directly in each of the frame’s
two power supply module bays. One is the primary supply and the is the secondary, or redun-
dant, supply. The PS8100s use a 15A circuit and standard IEC 15 A AC power cords.
The NV8140 uses the PS8300 module. A PS8300 can be installed directly in each of the frame’s
two power supply module bays. One is the primary supply and the is the secondary, or redun-
dant, supply. The NV8140 has two C19 power connectors and require 20A plant lines. The cable
supplied in North America has a NEMA L5-20P connector at the other end. For customers
outside North America, we ship these power cords with the NEMA end cut off.
The NV8280, NV8576, and NV8576-Plus use PS8300 power supplies, in an external NV8300
frame that holds up to four PS8300 power supply modules. Two are primary supplies and two
are secondary (or redundant) supplies. The NV8280 requires 1 NV8300 power supply frame. The
NV8576 requires 2 NV8300 power supply frames. The NV8576-Plus (two frames) requires 4
NV8300 power supply frames, 2 for each frame.
