NetVanta 1534/1544 Series Physical Descriptions61702590G1-34E Copyright © 2013 ADTRAN, Inc. 19NetVanta 1544 SeriesThe NetVanta 1544 Series is a Layer 3 managed switch. The entire series runs AOS, is managed through anEIA-232 CONSOLE port (DB-9), Telnet session, or GUI, and is RoHS compliant (telecommunicationsexemption). The NetVanta 1544 Series units are described in the following sections.The NetVanta 1544 is housed in a 1U-high, rack-mountable metal enclosure that is half the width of a standard19-inch rack, allowing two to be mounted side by side using an optional dual mounting tray. The NetVanta 1544includes a universal AC power supply and the front panels contain 24 10/100/1000Base-T Ethernet interfacesthat are accessed via standard RJ-45 connectors. Four industry standard 1000/2500Base-X SFP slots (supportingindustry standard SFP modules) are available on the rear panel for high-speed uplink via fiber or copper. TheNetVanta 1544 EIA-232 CONSOLE port (DB-9) is located on the rear of the unit.The NetVanta 1544P is housed in a 1U-high, rack-mountable metal enclosure that can be mounted in a standard19-inch rack. The NetVanta 1544P includes a universal AC power supply and the front panels contain24 10/100/1000Base-T Ethernet interfaces that are accessed via standard RJ-45 connectors. Four industrystandard 1000/2500Base-X SFP slots (supporting industry standard SFP modules) are also available on the frontpanel for high-speed uplink via fiber or copper. The NetVanta 1544P EIA-232 CONSOLE port (DB-9) islocated on the front of the unit.The NetVanta 1544F is housed in a 1U-high, rack-mountable metal enclosure that can be mounted in a standard19-inch rack and is available with either a 120 VDC or 240 VDC power supply. The front panel contains24 100/1000Base-X SFP interfaces that are accessed via fiber or copper using industry standard SFP modules.Four industry standard 1000/2500Base-X SFP slots (also supporting industry standard SFP modules) are alsoavailable on the front panel for high-speed uplink via fiber or copper. The NetVanta 1544F has expandablememory via CompactFlash. The NetVanta 1544F EIA-232 CONSOLE port (DB-9) is located on the front ofthe unit.Redundant Power SupplyAll NetVanta 1544 and 1544P 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 1544P 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 1544 Series units support four 1000/2500Base-X SFP slots on either the front or back panel thataccept a number of industry standard SFP modules. The SFP modules provide Gigabit Ethernet fiberconnectivity for high-speed uplinks or switch stacking. As well as the four 1000/2500Base-X SFP slots, theNetVanta 1544F units support 24 100/1000Base-X SFP interfaces that are accessed via fiber or copper usingindustry standard SFP modules.
