With growing number of Power-over-Ethernet
(PoE) powered edge devices, and the explosion
of multi-media trac and cloud-based apps on
the Local Area Network (LAN), having a resilient
network infrastructure is essential to your
business. And a key to having a resilient network
is to ensure uninterrupted power.
ADTRAN addresses this need with the
NetVanta 1131 RPS/EPS unit, which provides
redundant power and supplemental power to
the NetVanta 1600 Series, and redundant power
to the NetVanta 1500 Series Gigabit switches.
Hardware
e NetVanta 1131 has three Redundant Power
Supply (RPS) outputs and one External Power
Supply (EPS) output. e RPS outputs provide
backup power for a NetVanta 1500 or 1600 switch’s
internal power supply. e EPS output provides
370 watts of backup PoE for a NetVanta 1500 or
1600 PoE switch for PoE redundancy. In addition,
the EPS output provides 370 watts of additional
PoE for the NetVanta 1638P for a total of 740 watts
of available PoE budget power.
Alternate Power Supply
e NetVanta 1131 RPS/EPS unit provides
redundant power feeds via an alternate AC power
circuit. In this instance, the NetVanta switch
is connected to the primary AC circuit, and
connected to NetVanta 1131 RPS/EPS, which
is powered via an alternate AC power source.
Should the primary AC circuit fail, the
NetVanta 1131 RPS automatically provides
power feed to the connected NetVanta switch
eliminating any downtime.
Internal Power Supply Backup
e NetVanta 1131 RPS output provides
redundancy for NetVanta PoE and non-PoE
switches in the event of an internal power supply
failure. In the event the switch’s internal power
supply fails, the NetVanta 1131 would power the
NetVanta switch until the power unit is replaced or
swapped out.
Redundant PoE Budget
e NetVanta 1131 EPS output provides external
backup power supply to the NetVanta 1500 and
1600 Series PoE switches, in case the internal PoE
power supply fails. e NetVanta 1131 can provide
up to 370 watts of redundant PoE budget to ensure
PoE-powered edge devices such as VoIP phones,
wireless Access Points (APs) or IP security cameras
operate without interruption.
Supplemental PoE Power
e NetVanta 1131 EPS output can also provide
supplemental power up to 370 additional watts,
for the NetVanta 1638P Gigabit PoE switch. is
provides increased power wattage, eectively
doubling the available PoE budget, enabling the
NetVanta 1638P to support greater number of PoE
or PoE+-powered edge devices. e NetVanta 1131
EPS’ internal power management enables ecient
budgeting of available PoE power.
