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 Form-factor 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.
Advanced Security
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
Port-Based 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.
