Physical Descriptions NetVanta 1534/1544 Series14 Copyright © 2013 ADTRAN, Inc. 61702590G1-34E2. PHYSICAL DESCRIPTIONSNetVanta 1534 SeriesThe NetVanta 1534 Series is a Layer 3 Lite managed switch. The entire series runs ADTRAN OperatingSystem (AOS), is managed through an EIA-232 CONSOLE port (DB-9), Telnet session, or Web-basedgraphical user interface (GUI), and is RoHS compliant (telecommunications exemption). The NetVanta1534 Series units are described in the following sections.The NetVanta 1534 is housed in a 1U-high, rack-mountable metal enclosure that is half the width of a standard19-inch rack, allowing two units to be mounted side by side using an optional dual mounting tray. It includes auniversal AC power supply and the front panel contains 24 10/100/1000Base-T Ethernet interfaces that areaccessed via standard RJ-45 connectors. Two 1000Base-X small form-factor pluggable (SFP) slots and two2500Base-X slots (all supporting industry standard small SFP modules) are available on the rear panel forhigh-speed uplink via fiber or copper. The NetVanta 1534 EIA-232 CONSOLE port (DB-9) is located on therear panel.The NetVanta 1534P is housed in a 1U-high, rack-mountable metal enclosure that can be mounted in a standard19-inch rack and includes a universal AC power supply. The front panel contains 24 10/100/1000Base-TEthernet interfaces that are accessed via standard RJ-45 connectors. Two 1000Base-X SFP slots and two2500Base-X slots (all supporting industry standard SFP modules) are also available on the front panel forhigh-speed uplink via fiber or copper. The NetVanta 1534P EIA-232 CONSOLE port (DB-9) is located onthe front panel.Redundant Power SupplyAll NetVanta 1534 and 1534P units provide a connection for an optional RPS on the rear panel. TheNetVanta 1131 RPS/EPS (P/N 1700530F1) is sold separately. When connected, the RPS will provide 120 W ofbackup power should the internal power supply fail. The units will automatically switch to RPS when needed,providing uninterrupted power to the unit.Extended Power SupplyThe NetVanta 1534P 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. The units will automaticallyswitch to EPS when needed, providing uninterrupted power to the unit.SFP Module SlotsThe NetVanta 1534 Series units support two 1000Base-X and two 1000/2500Base-X SFP slots on either thefront or back panel that accept a number of industry standard SFP modules. The SFP modules provide GigabitEthernet fiber connectivity for high-speed uplinks or switch stacking. For a list of supported SFP modules, visitthe ADTRAN website at http://www.adtran.com.
