ADTRAN NetVanta 1535P
28-port PoE Layer 3 Lite Gigabit Ethernet Switch with ActivReach Technology

ADTRAN NetVanta 1535P

Sorry, this product is no longer available, Please contact us for a replacement.



The NetVanta 1535P utilizes ADTRAN’s ActivReach Ethernet Technology to break down existing cabling and distance constraints and unlocks the power of Ethernet to support all grades of wiring – CAT5, CAT3 or legacy copper. This technology also extends reach beyond limits of standard Ethernet – up to 1600 feet without the need for fiber, repeaters or additional switch infrastructure. Delivers 10/100 Mbps voice, data and even Power over Ethernet (PoE) over existing cabling.

ActivReach Ethernet Technology uses the combination of the NetVanta 1535P and the NetVanta ActivReach Media Converter.

The NetVanta® 1535P is a managed, 28-port PoE, Layer 3 Lite, Gigabit Ethernet switch with ActivReach Ethernet technology designed for ease-of-deployment, as well as fast, secure, costeffective Local Area Network (LAN) switching. Through its innovative design, the NetVanta 1535P allows for ultimate flexibility utilizing standard 10/100/1000Base-T Ethernet or ActivReach Ethernet for PoE and connectivity in a variety of cabling environments. In addition, this scalable, full-featured business-class switch was designed with Voice-over-IP (VoIP) applications in mind with the ability to supply Legacy Power over Ethernet (PoE), 802.3af (PoE), or PoE over ActivReach to power IP phones, as well as Gigabit-to-the-desktop deployments. Experience the ease of management with an easy-to-use Web-based Graphical User Interface (GUI) and familiar Command Line Interface (CLI).

ActivReach Ethernet Technology

In addition to standard 10/100/1000Base-T capabilities, the NetVanta 1535P features ADTRAN’s ActivReach Ethernet technology which allows speeds of 10/100 Mbps native Ethernet over voice-grade copper and over significant distances. Configurable per-port, ActivReach Ethernet is capable of delivering up to 15.4 W of PoE, as well as 10/100 Mbps of full-duplex link connectivity utilizing four-pair, two-pair or even a single-pair of CAT3 or higher cabling at distances of up to 1,600 feet. With ActivReach, the NetVanta 1535P is designed to easily deploy cutting-edge VoIP and UC technologies utilizing a building’s existing voice-grade wiring. In addition, with speeds up to 100 Mbps, ActivReach Ethernet also provides an extremely cost-effective means for desktop connectivity where CAT5 cabling does not already exist.


The NetVanta 1535P rackmount switch provides 28 Gigabit Ethernet ports, consisting of 24 fixed ports capable of 10/100/1000Base-T Ethernet or ActivReach Ethernet and four Small Formfactor Pluggable (SFP) ports.Together the four SFP ports can provide up to 14 Gbps of bandwidth between interconnected NetVanta 1535P switches. When using ActivReach mode, a Media Converter is used at the end-point to terminate ActivReach Ethernet and convert it to standard 10/100Base-T Ethernet and 802.3af (PoE) or Legacy PoE on the device-side. The Media Converter is powered using ActivReach and requires no external power supply.

Multi-layer Switching

The NetVanta 1535P supports advanced multilayer (Layer 2 and Layer 3 Lite) switching with up to 16 static routes allowing it to easily scale from SMBs to enterprise-size networks.

VoIP Ready

The NetVanta 1535P switch is VoIP-ready with the ability to automatically configure IP phones using LLDP-MED, and the ability to separate voice traffic onto voice VLANs, to simplify the deployment of VoIP. In addition, the switch includes a VoIP Setup Wizard (available via a web-based GUI or CLI), which automates the complete VoIP setup process reducing deployment time and eliminating errors. An on-demand VoIP report provides a printable summary of the switch VoIP configuration, as well as providing alerts and recommendations to improve performance. All NetVanta switches support QoS to prioritize VoIP traffic, 802.1p and DiffServ Class of Service (CoS).


The NetVanta 1535P provides standards-based 802.3af (PoE) and Legacy PoE for powering IP phones, Wireless Access Points (WAPs), or other devices requiring LAN power. In addition, PoE over ActivReach is supported to power devices over voice-grade cabling and over greater distances when used with the ActivReach Media Converter.


The NetVanta 1535P switch offers a variety of data security features including DoS protection, MAC-based port security, multilevel user passwords, Secure Shell (SSH) and Secure Socket Layer (SSL) for encrypted user login, and Access Authentication and Authorization (AAA) for authentication with RADIUS and TACACS+. With features such as 802.1x and port security, administrators can be assured that only authorized users are allowed access to the network.

The ADTRAN® Operating System (AOS) also features desktop auditing using DHCP in conjunction with Microsoft Network Access Protection (NAP) to monitor the health of client computers. The two protocols work together to ensure that systems connected to the network are using appropriate corporate policies, such as firewall settings and antivirus settings.

Port Scheduler

The NetVanta 1535P allows ports to be enabled or disabled based on time of day. This ability to schedule available ports allows for added security and reduces power consumption during off hours saving on utility cost.

iSCSI Optimized

All ADTRAN NetVanta Gigabit Ethernet switches are optimized for iSCSI Storage Area Networks (SANs) deployments. Network administrators can take advantage of features such as Jumbo frame support (up to 9K), separation of iSCSI network traffic utilizing VLANs, and 802.3x flow control to seamlessly integrate ADTRAN switches with iSCSI SANs devices.


AOS offers both a CLI and an intuitive Web-based GUI with step-by-step configuration wizards. For automating setup and configuration, the NetVanta 1535P supports Auto-Config which provides the ability to automatically obtain the switch configuration via DHCP.

AOS also offers network forensics to aid in troubleshooting network problems by allowing network administrators to easily locate devices on the network by MAC or IP address.
