Level One GEL-5261 User Manual

GEL-5261 Version: 1

KILBY 52-Port L2 Managed Gigabit Switch, 4 x
SFP

The LevelOne GEL-5261 is an intelligent L2 Managed Gigabit Switch with 48 RJ45 ports and 4 SFP fiber
slots, designed for enterprise or large workgroups connectivity applications with the non-blocking, wire­speed switching performance and advanced networking management functions.

The switch supports a flexible web-based management interface for both IPv4 and IPv6 as well as console,
SNMP and Telnet management access. Despite its affordable pricing, the GEL-5261 is equipped with many
advanced features such as Internet Group Management Protocol (IGMP) snooping, port-/MAC-/tag-based
VLAN, IEEE 802.1D/w/s Spanning Tree, Access Control List (ACL), IEEE 802.3az Energy Efficient
Ethernet, Link Aggregation Control Protocol (LACP), IEEE 802.1p QoS, Storm Control for protecting
against broadcast/multicast/unknown unicast and much more.

An ideal network solution for anyone looking for an affordable and efficient way to expand their network.
