Overview
Redundant Power Supplies
The Enterasys NAC Controller supports two fixed, auto‐ranging redundant AC power supply
modules. For power supply specifications, refer to "Power Supply" on page A‐2.
Power Supply LANVIEW LEDs
Power supply status is indicated by LANVIEW ® LEDs located on the front panel of the chassis.
Each power supply utilizes a single LED to monitor and detect power supply failure and
redundancy status. Refer to Chapter
explanation of the power supply LEDs and their definitions.
Power Supply Status Through System Management
The Enterasys NAC Controller power supplies report information to the NAC Controller PEP
installed in the chassis regarding their present operating status. This information includes the
following:
•
Power Supply ID (PS1, PS2)
•
Power Supply Status (normal/fault)
•
Power Supply Redundancy indication
Refer to the Enterasys Matrix DFE‐Diamond/Platinum Series Configuration Guide for instructions on
how to access power supply status information via Local Management.
Auto-Ranging Power Supplies
The Enterasys NAC Controller power supplies automatically adjust to the input voltage and
frequency, which allows for an input voltage of 100 to 240 Vac, and a frequency between 50 and
60
Hz. Refer to the operating specifications in Appendix
necessary. For installations in North America, two 15 A power cords are required. Refer to
"Powering Up a Enterasys Matrix
Power Supply Replacement
Power supplies in the Enterasys Matrix N1 chassis are fixed and, as such, are not considered
field‐replaceable units.
If a power supply must be replaced, contact Technical Support for information (refer to "Getting
Help" on page xviii).
Chassis Cooling System
The Enterasys Matrix N1 chassis backplane supports six 2‐wire 12v fans. General fan failure is
detected at the chassis backplane and the status is relayed to the module using the FTM2
connector.
The fans have one LANVIEW LED located on the front of the unit. This LED indicates the status of
the fans, either normal or fault condition. Since the fans are built into the chassis, there is no
support for a 'Fan Present' indicator. Refer to Chapter 2, Installation Requirements and
Guidelines, for a full description of fan LED states.
