24-Port PoE Gigabit Managed Switch

Name: 24-Port PoE Gigabit Managed Switch
Brand: Dahua
SKU: PFS4428-24GT-370

Stock Code: PFS4428-24GT-370

Carries twenty-four gigabit PoE ports to the backbone over four fiber uplinks.

A Layer 2 managed gigabit PoE switch for the access layer of campuses and multi-building sites. Twenty-four PoE ports feed cameras and access points, while four 1000 Base-X slots meet the fiber backbone. Management runs over Web, Telnet, SSH and SNMP.

PoE power per port

Each of the twenty-four ports feeds IEEE802.3af and IEEE802.3at devices straight over the cable.

4slots

Gigabit fiber uplinks

The 1000 Base-X slots carry four separate fiber runs to the backbone and open the way to a redundant topology.

4.1Mb

Packet buffer memory

Buffers packets during traffic bursts and reduces frame loss in video streams.

2KV

Lightning protection

Absorbs common-mode surges and protects ports wired to outdoor camera runs.

4.37kg

Rack-ready chassis

The 440 mm wide metal chassis sits on standard cabinet rails.

IN DAILY USE

Redundant backboneSTP, RSTP and MSTP close loops and move traffic to a backup path when a link drops.

Remote managementThe Web interface, Telnet, SSH and SNMP manage the same switch, so the field team changes settings without walking to the cabinet.

Storm controlBroadcast, unicast and multicast storm control cuts the traffic that floods the network and keeps camera video flowing.
