1 TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD2254EP is a 6-port lite managed industrial ethernet switch with four Gigabit RJ45 and two Gigabit
SFP uplink ports which can be used as standard ports or as a redundant fiber ring using OSD’s proprietary
ring protocol. Each RJ45 can provide up to 60W PoE to power a wide range of devices. Along with higher
level features including SNMP, VLAN and IGMP snooping the OSD2254EP is suitable for use in critical
networks. A rugged IP30 casing, fan-less design and wide operating temperature range from -40 to +75ºC
make it suitable for use in a wide range of harsh industrial environments.
1.1.2 FEATURES AND BENEFITS
▲ Complies with IEEE802.3i/802.3u/ 802.3ab
10/100/1000Base-T, IEEE802.3z
1000Base-Lx/Sx standards
▲ Has a total of six ports: four fixed copper
ports for 10/100/1000Base-T and two SFP
ports for the fiber ring or non-ring
(100Base-Fx or 1000Base-X)
▲ A network diameter of hundreds of
kilometers is practical
▲ Ring reconfiguration in the case of cable or
switch failures takes less than two
milliseconds per hop

crossover cables
▲ Can be used with either 1 or 2 singlemode
or multimode fiber over a variety of link
budgets via plug in SFP module (sold
separately)
