Accton ES3526YA L2 Datasheet

The CheetaSwitch ES3526YA is a switch with 24
Auto-MDI/X 10BASE-T/100BASE-TX ports, 2
ComboG (RJ-45/SFP) ports and 2 built-in stacking
ports. With the capability of up to 8 stacking units, it is
loaded with features such as VLANs, GVRP and
IGMP, thus provide an easy-to-configure and
easy-to-manage network environment. ES3526YA is
perfect for cost-sensitive medium to large network
looking to strengthen its network connection.

ES3526YA L2 Fast Ethernet
Stackable Switch

High Performance

Provides high performance architecture with 12 Gbps
total capacity. GVRP allows automatic configuration
of VLAN, IGMP snooping to identify multicast traffic to
make an efficient utilization of the switch bandwidth.
Aggregate grater bandwidth between devices by
supporting IEEE 802.3ad (LACP). IEEE 802.1p four
queues help to prioritize time-sensitive applications
such as multimedia voice traffic.

Advanced Stack Ability

Allow up to 8 ES3526YA switches to be connected via
four Gigabit bandwidth stackable module to create a
virtual manageable switch.

Flexible Uplink SFP ports

Two SFP ports support both single mode and multi
mode Gigabit fiber to allow network managers the
flexibility to upgrade their networks based on their
requirements.

Security and Redundancy

Port-based MAC filtering prevents unauthorized user
to access to the switch. IEEE 802.1D Spanning Tree
Protocol support for loop-free network improves fault
tolerance and simplifies network configuration. RPU
connectivity provides power fault tolerance to ensure
a reliable system.

Comprehensive Manageability

The system can be managed and monitored via
SNMP/RMON protocol through computer using
network management software or via an Internet web
browser. Comprehensive LED indicators are located
on the front panel to assist network administrators in
troubleshooting. Port Mirroring feature provides a
non-intrusive mechanism for traffic inspection across
the whole switch. With the help of our powerful
management features the status of the
CheetahSwitch can be obtained at a glance.

The CheetaSwitch ES3526YA is a Layer 2 stackable switch with 24

10/100BASE-T(RJ-45) ports and two ComboG (RJ-45/SFP) ports for Gigabit
uplink and two 1Gbps port for stacking. The stackings port can also be used
as normal Gigabit uplink ports in standalone mode.

The ES3526YA can be managed either by in-band management via the
network station remotely or out-of-band management via the console port
(RS232) locally.
