NetVanta 1600 Series Hardware Installation Guide
2.

PHYSICAL DESCRIPTIONS

The NetVanta 1600 Series is a 48-port multi-layer Gigabit Ethernet switch. These high-capacity Ethernet
switches provides Layer 2 and Layer 3 switching capability. Two dual high-speed option module slots provide
optional 10 G interfaces. Applications for the NetVanta 1600 Series include edge switching with high-speed
stacking and network aggregation.
The NetVanta 1600 Series units' front panels contain 48 10/100/1000Base-T Ethernet interfaces that are
accessed via standard RJ-45 connectors. Also, on the front panel a Type A universal serial bus (USB) host
connector is integrated into the 10/100Base-T (RJ-45) management port.
The NetVanta 1600 Series is housed in a 1U-high rack-mountable metal enclosure that includes field replaceable
power supplies and fans. The NetVanta 1638 is shipped with the NetVanta 120 W AC power supply
(P/N 1700460F1) installed that provides +12 VDC and a redundant power supply (RPS) connector. The
NetVanta 1638P is shipped with the NetVanta 500 W PoE power supply (P/N 1700462F1) installed that
provides +12 VDC and +50 VDC and both an RPS and an extended power supply (EPS) connector.
NetVanta 1600 Series units run the ADTRAN Operating System (AOS), and are managed through an
EIA-232 (DB-9) console port located on the front panel, a 10/100Base-T Ethernet management port, Telnet
session, or the Web-based graphical user interface (GUI). The NetVanta 1600 Series is RoHS compliant.

ActivChassis

ActivChassis is a feature of the NetVanta 1600 Series in which multiple devices, such as Layer 2 or Layer 3
switches, are connected to create a virtual chassis that can be managed as a single virtual switch. The devices are
stacked using ActivChassis ports to create a larger logical device comprised of the individual devices. This
feature allows multiple devices to share resources and operate as though they are part of a larger chassis-based
system, while allowing configuration and control of the logical device from a single member. In ActivChassis,
each device adds its set of ports and hardware tables to form a logical device. Refer to the ActivChassis in AOS
configuration guide available on the ADTRAN Support Forum for more information on configuring the
NetVanta 1600 Series for ActivChassis.

Power over Ethernet

The NetVanta 1638P PoE device provides the same basic functionality as the NetVanta 1638 product. By
default, the PoE switch discovers attached powered devices (PDs) and provides 50 VDC to the PD via Ethernet
cabling. The NetVanta 1638P is fully compliant with the IEEE 802.3af PoE and IEEE 802.3at PoE+ standards
and also supports legacy PDs.

Redundant Power Supply

All NetVanta 1600 Series units provide 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 34 for more information.

Extended Power Supply

The NetVanta 1638P unit also provides a connection for an optional EPS on the rear panel. The NetVanta 1131
RPS/EPS (P/N 1700530F1) is sold separately. When an EPS is connected, the internal and external supplies will
use load sharing to provide up to 740 W of power for PoE applications. In the event that the internal power
supply fails, the EPS will provide up to 370 W of power for PoE applications. Refer to NetVanta 1131 RPS/EPS
on page 34 for more information.
