The CheetaSwitch ES3526Y is a switch with 24
Auto-MDI/X 10BASE-T/100BASE-TX ports, 2
optional expansion slides in modules and 2
build-in 2 Ports. With the capability of up to 8
stacking units, it is loaded with features such as
VLANs, GVRP and IGMP, thus provide an easyto-configure and easy-to-manage network
environment. ES3526Y is the perfect for costsensitive medium to large network looking to
strengthen its network connection.
ES3526Y L2 Fast Ethernet/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 dual
queues help to prioritize time-sensitive
applications such as multimedia traffic.
Advanced Stack Ability
Allow up to 8 ES3526Y switches to be
connected via four Gigabit bandwidth stackable
module to create a virtual manageable switch.
Flexible Uplink Modules
Two expansion slots supports five different
media configuration and port densities 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.
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 ES3526Y is a Layer 2 stackable switch with 24 10/100
BASE-T(RJ-45) ports and two expansion slots for Gigabit or 100Base-Fx fiber
interface.
The ES3526Y can be managed either by in-band management via the network
station remotely or out-of-band management via the console port (RS232) locally.
