INTEGRATED LOCKING SYSTEM OF POWER CORDS AND RACK IPDU OUTLETS PREVENT COSTLY DOWNTIME FROM ACCIDENTAL POWER CORD DISCONNECTS WITH SECURELOCK OUTLETS AND POWER CORDS. Despite meticulous planning and stringent processes, a source of data center downtime is human error and accidents. All too often, when site services technicians labor in the rear of cabinets - whether commissioning new servers, replacing faulty power supplies, or routing LAN/SAN cables - power cords become accidentally dislodged as personnel brush against power cords in the rear of a cabinet. Plugs can also vibrate loose. In modern data centers the use of high-current IEC C-19/C-20 connections proliferate with the increased deployment of blade servers. The large C-20 connector and cord are heavy so C-20 plugs are prone to accidental disconnection. To resolve this problem, Raritan equips all of its latest rack iPDUs that have IEC C-13 or C-19 outlets* with patented SecureLock receptacles. SecureLock outlets interoperate with standard AC power cords as normal. But when mated with genuine SecureLock AC power cords, a positive, locking, physical connection holds the cords in place with tabs. Like all Raritan power strips, these IEC C-13 and C-19 outlets are UL Listed (N. America) / VDE Listed (Europe / International).
