OS6855-24D, Alcatel-Lucent OS6855 Switch, 20x1G RJ45/4xCombo Ports/PoE Capable

Alcatel-Lucent’s OS6855-24D is a robust enterprise-level hardened ethernet switch designed for network deployments requiring high durability, flexible power options, and resilience in harsh environments. As a fully managed gigabit switch, the OS6855-24D supports 20 x 10/100/1000 RJ45 ports and 4 shared SFP slots, making it ideal for reliable data aggregation at the edge or within industrial and mission-critical applications. With advanced authentication methods like Secure Shell (SSH), RADIUS, TACACS+, and LDAP, it ensures secure network access, while full support for MD5 and PKI encryption cements its role in enhancing data security. The OS6855-24D offers PoE ports versatility to support a range of powered devices—even where voltage requirements or physical access are challenging—demonstrating inherent strength as a hardened gigabit switch purpose-built for demanding scenarios. Hardware and software features such as VLAN support, broadcast storm control, full QoS, and software flow control increase operational agility. Furthermore, its compliance with stringent international standards (including MIL-STD 810F/901D, EN 61000 series, UL, CSA, IEC) proves its readiness for harsh environments across Asia, Europe, Africa, and North America. Status LEDs, rackmountable 1U design, and manageable operation via SNMP, SSH, and HTTPS allow seamless adoption by distributors, system integrators, or enterprise end-users. As digitalization escalates, especially at the edge or in infrastructure modernization, OS6855-24D’s hardened ethernet switch architecture ensures continuous high-speed connectivity and exceptional network reliability throughout the most challenging deployments.
