Product Specifications
The 250 W hot-swappable, redundant power supply provides 12V and 12VSB outputs and the AC input is auto-ranging with power factor correction. In addition, the
power supply includes an outward-facing fan and is 80 PLUS Bronze compliant. Two of these power supplies can be used simultaneously with the NetVanta 1760-
12F switch; for mission critical operations where downtime needs to be minimized, this hot-swappable redundant AC power supply can protect against a single
power supply failure. You can install up to two PSUs with matching airflow direction in the NetVanta 1760-12F switch. The PSUs operate in a load-sharing mode and
provide 1+1 redundancy.
Power
The 250 W redundant power supply modules require power from an external AC power supply that can provide 100 to 240 VAC, 50-60 Hz. A standard AC power
socket is located on the rear panel on the PSU. The power socket is for the AC power cord (as shown in
on page 1).The following table summarizes the
power information for the PSU.
LED Description
The PSU also includes an AC power status LED. This LED is described in the following table.
Connecting to AC Power
To supply AC power to the switch in which the PSU resides, first verify that the external AC power supply can provide 100 to 240 VAC, 50-60 Hz, 4 A maximum.
Next, install the PSU(s) in the switch and connect it to AC power.
NOTE
g
1+1 redundancy is a system where a switch power supply is backed up by another switch power supply in a load-sharing mode. If one power supply
fails, the other power supply takes over the full load of the switch.
CAUTION!
f
CAUTION!
f
The switch includes plug-in power supply modules that are installed into its chassis. All installed modules must have a matching airflow direction.
That is, all modules must have a front-to-back (F2B) airflow direction, or all modules must have a back-to-front (B2F) airflow direction. The airflow
direction of PSUs are indicated by labels on the modules.

Indication
AC
Off
External power is not connected or has failed.
Green (solid)
External AC power is connected to the module.
Green (flashing)
External AC power is present but only the 12 VSB power supply is on.
Amber (solid)
External AC power cord is unplugged or AC power is lost, if a second PSU is installed, indicates the second
power supply in parallel still has AC input power.
Can also indicate a critical event with the power supply has caused a shutdown.
Amber (flashing)
Power supply warning events have been detected where the power supply continues to operate; such as
high temperature, high power, high current, or slow fan events.
WARNING!
f
■ This equipment is intended to be installed and used only by instructed or skilled persons.
■ The appliance coupler (the connector to the unit and not the wall plug) must have a configuration for mating with an EN 60320/IEC 320 appliance
inlet.
■ The AC branch circuit socket-outlet must be installed near the equipment and must be easily accessible.
