Ethernet Access Switch MES2124M

Overview
Specifications
Reviews
  • Advanced L2 functions
  • Stacking support
  • Multicast support (IGMP Snooping, MVR)
  • Advanced security functions (L2-L4 ACL, IP Source Guard, Dynamic ARP Inspection, etc.)
The switches provide end users connection to the networks of large enterprises, small and medium-sized businesses and service provider networks using Fast and Gigabit Ethernet interfaces .
The access switches support physical stacking, VLANs and multicast groups, as well as advanced security features.

Uninterruptible power supply
MES1124MB and MES2124MB switches have the ability to connect storage battery in order to provide uninterruptible power in case of 220V supply line failure.
The switches are equipped with the power supply unit that allows charging of storage battery if the 220V supply line is available. The power system provides monitoring of power supply line and notifies of power source switching.

Protection against voltage surges
MES switches are equipped with efficient protection technology against voltage surges (up to 6 kV) caused by lightning discharges.
