AC Power Supplies

Two 800 watt (PoE) and two 460 watt AC power supply models, which you must order separately,
are available for the 7100G-Series switch depending upon the model:
71G21K2L2-48P and 71G21K2L2-24P24:
• 71A-POE-A – I/O port side air exhaust
• 71A-POE-B – I/O port side air intake
71G11K2L2-48:
• 71A-PS-A – I/O port side air exhaust
• 71A-PS-B – I/O port side air intake
Each power supply option contains a single non-reversible fan. The two power supply options for
each 7100-Series model are differentiated by the direction of the power supply fan air flow. Power
supply air flow must agree with the air flow direction of the installed fan modules.
The 7100G-Series AC 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. See the
operating specifications in
For installations in North America, a 15 Amp power cord is required. See
7100G-Series
You can install up to two power supplies in the 7100G-Series chassis. All the power supply needs
of the 7100G-Series switch can be met by installing a single power supply. If you choose to use two
power supplies, system power redundancy is guaranteed if one supply is lost. Power supplies are
hot swappable in redundant power supply mode.

power supply LED, see

Fans

The 7100G-Series switch comes with a single installed fan module to cool the system. The
direction of the fan module air flow is reversible. By default air flows from the power supply side
to the switch I/O port side of the unit. If your 7100G-Series switch configuration requires switch I/
O port side to power supply side air flow, see
for details about how to reverse the fan module air flow.
The 7100G-Series fan module is field replaceable. For information on how to replace 7100G-Series
fan module, see

Micro-USB Port

The micro-USB port is provided for local file transfer.

Management

You can manage the 7100G-Series switch either in-band or out-of-band. In-band remote
management is possible using the Enterasys Networks' NetSight
command line interface (CLI) via Telnet. Out-of-band management is provided through the RJ45
COM (Communication) port on the front panel using a PC, a VT terminal, or a VT terminal
emulator. For more information, see
