Industrially Hardened (24) 10/100/1000 BASE-TX
+ (4) 1000BASE-FX Managed Ethernet Switch
CNGE28FX4TX24MS
24 + 4FLEXIBILIT YINCLUDEDHARDENED ALL GIGABIT
The ComNet™ CNGE28FX4TX24MS Layer 2 Managed 28 Port Ethernet Switch
supp orts t wenty-four (24) 10/100/100 0BASE-TX ports and four (4) 1000BASEFX ports of Ethernet data. The four 1000BASE-FX ports are SFP* configurable
for fiber type (multimode or single-mode), connector type and distance. The
exclusive C-Ring redundant ring feature protects networks from interruptions
or temporary malfunctions with its fast recovery technology. The electrical
ports suppor t the 10/100/1000 Mbps Ethernet IEEE 802.3 protocol, and autonegotiating and auto-MDI/MDIX features are included. The CNGE28FX4TX24MS
are optically (1000BASE-FX) and elec trically compatible with any IEEE 802.3
compliant Ethernet device.
FEATURES
› 56 Gbps Backplane
› IGMP v2/v3 (IGMP snooping support) for filtering multicast
traffic
› Port Trunking for ease of bandwidth management
› Supports 24 Gigabit Ports, and four 1000BASE-FX optical
ports with optional ComNet SFPs
› Power supply for switch operation is completely self-
contained within the switch
› Designed to meet full compliance with the environmental
requirements (ambient operating temperature, mechanical
shock, vibration, humidity with condensation, high-line/lowline voltage conditions and transient voltage protection) of
NEMA TS-1/TS-2 and the Caltrans Specification for Traffic
Signal Control Equipment.
