The rackmount 28 Port Gigabit L2+ Managed Switch RS428 has 20 Giga copper ports, four Giga combo ports, and four 100M/1G fiber SFP slots. It supports critical cybersecurity features such as Port-Based Security - IEEE802.1 x MAB (MAC Authentication Bypass), Access Control List (ACL, MAC/IP/ARP filter), DHCP Snooping, IP Source Guard and Dynamic ARP Inspection as well as advanced redundancy features. The rugged design and high EMC immunity makes the RS428 an ideal solution for power substation, industrial control room, roadside traffic control, and industrial Surveillance applications.
