H3C S5100 Series Ethernet Switches (hereinafter referred to as the H3C S5100 series) are Gigabit Ethernet switching products developed by H3C Technology Co., Ltd. The H3C S5100 series provide a variety of service features. The H3C S5100 series are designed as convergence and access devices for intranets and metropolitan area networks (MANs), and can also be used for connecting data center server clusters.

& Note:

Both 10 G interface slot 1 and 10 G interface slot 2 can be used for XFP interface cards, stack cards, and XENPAK optical modules.

III. Power supply system

An S5100-26C-EI switch provides AC power input and RPS DC input. The AC/DC power inputs can be used at the same time, acting as backup for each other. Alternatively, you can use either the AC power input alone or the DC power input alone. Make sure you use an RPS module recommended by H3C as the DC power input.

l AC input:

Rated voltage range: 100 VAC to 240 VAC; 50 Hz or 60 Hz

Max voltage range: 90 VAC to 264 VAC; 47 Hz to 63 Hz
