Introducing C21 Locking Power Cords

StayOnline is proud to announce the launch of C21 S-Lock and Dual-Lock power cords.

C21 S-Lock and Dual-Lock Power Cords are the first power cords on the market to feature a C21 locking connector. C21 locking power cords are compatible with Cisco equipment and are particularly well-suited for data centers and other business applications where uptime is critical.

C21 locking power cords are specifically designed to provide a reliable power connection for high-end computing equipment, including servers and networking hardware like those manufactured by Cisco. Cisco equipment, known for its role in critical networking infrastructures now has a locking option for C21 connections.

Configurations include:

• C14 to C21 - Dual-Lock and S-Lock configurations
• C20 to C21 - Dual-Lock and S-Lock configurations

The C21 female connector is rated for a higher temperature than the C19 connector. Like a C19, C21 can connect to a C20 inlet. C21 is also compatible with C22 inlets whereas the C19 is not.

Dual-Lock versus S-Lock

The S-Lock connector uses a twist to lock mechanism. There is a low-profile collar on the end of the unit that can be twisted clockwise to lock and counterclockwise to release. No proprietary inlet is required.

Dual-Lock power cords have a universal S-Lock connector on the female end of the cord and a proprietary P-Lock on the male end of the cord making them an end-to-end locking solution. P-Lock plugs work with select ServerTech, Raritan, Eaton, Emerson Knurr, and Great Lakes PDU. Consult your owner's manual to verify if your PDU is configured to accept P-Lock power cords.

S-Lock and Dual-Lock power cords are UL listed with North American conductor colors. Color options include red, blue, and black.
