OVERVIEW
NS3500-24T-4C
This Enterprise-Class Network Switch provides 24 Gigabit Ethernet
ports with 4 shared 100/1000Mbps SFP slots. This switch provides a
high-performance switch architecture and non-blocking switch fabric
capable of wire-speed throughput as high as 48Gbps.
User-Friendly Traffic Control
Designed to deliver optimal IP video transmission performance for
applications with limited network resources, the NS3500-24T-4C
offers user-friendly traffic management features, including quick and
simple QoS configuration through a Web interface.
Flexible Management
The NS3500-24T-4C is equipped with console, Web and Simple
Network Management Protocol (SNMP) management capabilities,
and can be accessed via telnet. It also supports secure remote
management via a SNMPv3 connection which encrypts the packet
content at each session.
NS3500-24T-4C
Layer 2 (Non-PoE)
NS3702-24P-4S
Layer 3 (PoE-at)
The NS3702-24P-4S supports standard SNMP and includes an
advanced SNMP feature set to monitor the status of the switch and
traffic per port. The switch can also be monitored via any standardsbased SNMP management software.
Full Power, Isolated per Port PoE
The NS3702-24P-4S provides optimized deployment and safe power
management to PoE edge devices such as IP Surveillance cameras,
access control panels, wireless access points (WAP) and Voice over
IP (VoIP).
Full power PoE-af (15.4w) is provided to all 24 ports with no power
sharing, and added port circuit protection isolates and prevents power
interference between ports. In addition to standard IEEE 802.3af
(15.4w), the NS3702-24P-4S provides support for up to 14 ports of
IEEE 802.3at (30w) PoE+.
Built-in Monitoring, Diagnostics and Trouble-Shooting Tools
Quiet, Energy-Efficient Technology
Designed as a fanless switch, the NS3500-24T-4C provides a quiet,
energy-efficient, high-speed network environment, delivering Gigabit
performance at a cost similar to Fast Ethernet.
NS3702-24P-4S
This Enterprise-Class Network Switch is engineered to meet a variety
of high-performance applications, including PoE distribution, optical
network architectures and high-density performance through reliable
technology and advanced Layer 3 networking features.
Simple Web Management
All switch management functions, including Port Speed Configuration,
Port Link Aggregation, IEEE 802.1Q VLAN and Q-in-Q VLAN, Port
Mirroring, Rapid Spanning Tree and ACL security can be programmed
via a simple, yet powerful GUI interface.
The NS3702-24P-4S can be configured to monitor the status of a
connected PD (Powered Device) in real-time via IP ping. If a PD (IP
Camera, IP Access Reader, IP Intercom, VoIP phone, Wireless Access
Point) no longer responds to a ping, the switch will cycle PoE power
on the port, thus rebooting the PD to operational status.
Other features for enhanced troubleshooting and management include
PoE monitoring, management and scheduling to support energysavings, built-in cable diagnostics, and support for SNMP – all designed
to help reduce IT time and costs while keeping network downtime to a
minimum.
Static Routing
The NS3702-24P-4S supports IPv4/IPv6 Layer 3 static routing,
providing a cost-effective solution for inter-VLAN routing in a LAN
production network. This allows flexible network design and greater
control of network traffic – essential for larger IP Video systems.

Note: These switches require a Small Form-factor Pluggable (SFP) for optical uplink
use. IFS SFPs are available for multi-mode, single mode, and 1 or 2 fibers for various
transmission distances over optical fiber. Please refer to the IFS SFP data sheet to
select the appropriate SFP for your particular application needs. IFS S20 or S30 series
SFPs are recommended. Gigabit SFPs (S30) are recommended for best trunking
bandwidth performance.
