Cisco SF250-48HP - 48-port PoE switch with Gigabit uplink ports

It is a Cisco manageable switch with 48 RJ45 ports with PoE/PoE+ support, 2 SFP/RJ45 Combo ports and 2 Gigabit SFP ports. The switch offers advanced layer 2 functions and layer 3 routing. The switch can power other 802.3af/at compliant devices with up to 30 W per port. Maximum PoE power for all ports is 195 W.

Reliability of the Cisco brand

Cisco switches are covered by a limited, lifetime warranty. The manufacturer's limit for failure-free operation is 280 thousand hours (MTBF at 50°C), which means in practice that the switch will work without faults throughout its entire life.
