Physical Descriptions NetVanta 1600 Series Hardware Installation Guide14 Copyright © 2013 ADTRAN, Inc. 61700568F1-34D2. PHYSICAL DESCRIPTIONSThe NetVanta 1600 Series is a 48-port multi-layer Gigabit Ethernet switch. These high-capacity Ethernetswitches provides Layer 2 and Layer 3 switching capability. Two dual high-speed option module slots provideoptional 10 G interfaces. Applications for the NetVanta 1600 Series include edge switching with high-speedstacking and network aggregation.The NetVanta 1600 Series units’ front panels contain 48 10/100/1000Base-T Ethernet interfaces that areaccessed via standard RJ-45 connectors. Also, on the front panel a Type A universal serial bus (USB) hostconnector 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 replaceablepower 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. TheNetVanta 1638P is shipped with the NetVanta 500 W PoE power supply (P/N 1700462F1) installed thatprovides +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 anEIA-232 (DB-9) console port located on the front panel, a 10/100Base-T Ethernet management port, Telnetsession, or the Web-based graphical user interface (GUI). The NetVanta 1600 Series is RoHS compliant.ActivChassisActivChassis is a feature of the NetVanta 1600 Series in which multiple devices, such as Layer 2 or Layer 3switches, are connected to create a virtual chassis that can be managed as a single virtual switch. The devices arestacked using ActivChassis ports to create a larger logical device comprised of the individual devices. Thisfeature allows multiple devices to share resources and operate as though they are part of a larger chassis-basedsystem, 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 AOSconfiguration guide available on the ADTRAN Support Forum for more information on configuring theNetVanta 1600 Series for ActivChassis.Power over EthernetThe NetVanta 1638P PoE device provides the same basic functionality as the NetVanta 1638 product. Bydefault, the PoE switch discovers attached powered devices (PDs) and provides 50 VDC to the PD via Ethernetcabling. The NetVanta 1638P is fully compliant with the IEEE 802.3af PoE and IEEE 802.3at PoE+ standardsand also supports legacy PDs.Redundant Power SupplyAll NetVanta 1600 Series units provide a connection for an optional RPS on the rear panel. The NetVanta 1131RPS/EPS (P/N 1700530F1) is sold separately. When connected, the RPS will provide 120 W of backup powershould the internal power supply fail. The units will automatically switch to RPS when needed, providinguninterrupted power to the unit. Refer to NetVanta 1131 RPS/EPS on page 34 for more information.Extended Power SupplyThe NetVanta 1638P unit also provides a connection for an optional EPS on the rear panel. The NetVanta 1131RPS/EPS (P/N 1700530F1) is sold separately. When an EPS is connected, the internal and external supplies willuse load sharing to provide up to 740 W of power for PoE applications. In the event that the internal powersupply fails, the EPS will provide up to 370 W of power for PoE applications. Refer to NetVanta 1131 RPS/EPSon page 34 for more information.
