PHYSICAL DESCRIPTIONS
NetVanta 1235P
The NetVanta 1235P is a Layer 3 Lite managed switch. It runs AOS, is managed through an EIA-232
CONSOLE
port (DB-9), Telnet session, or GUI, and is RoHS compliant (telecommunications exemption).
The NetVanta 1235P is described in the following sections.
The NetVanta 1235P is housed in a 1U-high, rack-mountable metal enclosure that can be mounted in a standard
19-inch rack and includes a universal AC power supply. The front panel contains 24 10/100Base-T Ethernet
interfaces that are accessed via standard RJ-45 connectors. The 24 10/100Base-T Ethernet interfaces support
both Ethernet and ADTRAN’s ActivReach Ethernet. Two 1000Base-X SFP slots and two 2500Base-X slots (all
supporting industry standard SFP modules) are also available on the front panel for high-speed uplink via fiber
or copper. The NetVanta 1235P EIA-232
CONSOLE
port (DB-9) is located on the front panel.
ActivReach Ethernet
The NetVanta 1235P has 24 10/100Base-T Ethernet ports that support both standard and ADTRAN’s
ActivReach Ethernet. When used in conjunction with the NetVanta ActivReach Media Converter
(P/N 1702595G12), the NetVanta 1235P converts standard Ethernet to ActivReach Ethernet, which supports
rates of 10/100 Mbps over 1-, 2-, and 4-pair infrastructure wiring at cable distances beyond 100 meters.
For applications requiring connection into a single RJ-21, a hydra interconnect cable (P/N 1702595G14) can be
used. The hydra interconnect cable is suitable for 10 Mbps applications only. See
Table A-4 on page 41
for the
hydra cable’s 50-pin Champ connector pinouts.

Redundant Power Supply
The NetVanta 1235P unit provides a connection for an optional RPS on the rear panel. The NetVanta 1131
RPS/EPS (P/N 1700530F1) is sold separately. When connected, the RPS will provide 120 W of backup power
should the internal power supply fail. The units will automatically switch to RPS when needed, providing
uninterrupted power to the unit. Refer to
NetVanta 1131 RPS/EPS on page 29
for more information.
Extended Power Supply
The NetVanta 1235P unit also provides a connection for an optional EPS on the rear panel. The NetVanta 1131
RPS/EPS (P/N 1700530F1) is sold separately. In the event that the internal power supply fails, the EPS will
provide up to 370 W of power for PoE applications. The units will automatically switch to EPS when needed,
providing uninterrupted power to the unit. Refer to
NetVanta 1131 RPS/EPS on page 29
for more information.
SFP Module Slots
The NetVanta 1235P unit supports two 1000Base-X and two 1000/2500Base-X SFP slots on the front panel that
accept a number of industry standard SFP modules. The SFP modules provide Gigabit Ethernet fiber
connectivity for high-speed uplinks or switch stacking. For a list of supported SFP modules, visit the ADTRAN
