Product Data Sheet
NS2503-24P/2C
24-port Fast Ethernet Layer 2 PoE Managed Switch
Overview
Designed to provide fast and efficient connectivity from the
network edge to a backbone switch or server, the IFS 24-port
Fast Ethernet PoE Managed Switch series features 24
10/100Mbs Ethernet ports with full power isolated PoE ports.
The 2 Gigabit TP/SFP combo
ports can be either 10/100/1000Mbps (RJ45) or Gigabit only
(1000Base-SX/BX/LX/LHX/ZX) through an SFP (Small Formfactor Pluggable) GBIC interface.
This switch series is designed with a high-performance switch
architecture capable of providing a non-blocking switch fabric
with wire-speed throughput as high as 8.8 Gbps.
Robust Layer 2 Features
For efficient switch management, the IFS 24-port Fast Ethernet
PoE Managed Switch series is easily programmable, via a
simple, yet powerful Web interface. This switch can be
managed for functions such as Port Speed Configuration, Port
Link Aggregation, IEEE 802.1Q VLAN and Q-in-Q VLAN, Port
Mirroring, Rapid Spanning Tree and ACL security. The switch
also includes advanced features such as Multicasting with
IGMP snooping and query, QoS (Quality of Service), broadcast
storm and bandwidth control to enhance bandwidth utilization.
These switches support standard Simple Network Management
Protocol (SNMP) and include an advanced SNMP feature set to
monitor the status of the switch and traffic per port. The switch
can also be monitored via any standards-based SNMP
management software.

This switch series also offers comprehensive Layer 3 and Layer
4 Access Control List (ACL) to filter out unwanted traffic. Its
protection mechanisms are comprised of RADIUS and PortBased 802.1x user and device authentication. In addition, the
switches provide MAC filter, Static MAC, IP/MAC binding and
Port Security for enforcing security policies to the edge. With
IFS enterprise-class switches, a network administrator can now
construct a highly secure network with considerably less time
and effort.
