Why this model

Product Features

What this model is for, what it does well, and what to confirm before it goes on a project.

Best for

Use it to build a managed gigabit backbone for multi-camera IP surveillance networks that need VLAN separation and SFP uplinks.

Before you orderConfirm your rack space, 12 VDC power availability and whether your uplink modules match the two 1000 Mbps SFP ports before ordering.
01
Managed Network Control

Web-based management with VLAN and IEEE 802.1x support lets you segment camera traffic and control access on one switch.

02
Flexible Fiber Uplinks

Two 1000 Mbps SFP ports let you link distant cabinets or uplink to a core switch without extra media converters.

03
Resilient Link Design

STP, RSTP and static or LACP link aggregation help keep surveillance traffic flowing if a link or path fails.
