OnAccess 1224M is a configurable 24 + 2G managed layer 2 Optical
Ethernet Switch, which offers up to 24 configurable and modularized
100Base-FX or 10/100Base-TX ports, and two 10/100/1000Base-TX or
optional SFP 1000Base-X ports for flexibility and fast connection
speeds. OnAccess 1224M allows administrators to configure features,
monitor performance, and troubleshoot the switches using a standard
Web browser SNMP-based network management platform.
