characteristics of the units, introduces basic functionality, and provides installation instructions.
•Physical Descriptions on page 14
•Product Specifications on page 21
•Option Modules on page 24
•Unit Installation on page 26
For additional information on mounting options, powering the unit, and installing option modules, refer to the
following sections:

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. Virtual chassis functionality is also supported.
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 +54 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.
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 48 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 (Future Release)
All NetVanta 1600 Series units provide a connection for an optional RPS on the rear panel. The NetVanta 1162
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.
Extended Power Supply (Future Release)
The NetVanta 1638P unit also provides a connection for an optional EPS on the rear panel. The NetVanta 1162
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.
NetVanta 1600 Series Shipping Contents
Each NetVanta 1600 Series unit is shipped in its own cardboard shipping carton. Open each carton carefully, and
avoid deep penetration into the carton with sharp objects.
After unpacking the unit, inspect it for possible shipping damage. If the equipment has been damaged in transit,
immediately file a claim with the carrier and contact ADTRAN Customer Service (refer to the Repair and
Return section of the Support page on the ADTRAN website).
