Connection Guidelines for AC-Powered Systems

For connecting the Cisco MDS 9250i switch switch AC power supplies to the site power source, follow these basic guidelines:

•Each power supply should have its own dedicated branch circuit.

•For international, circuits should be sized according to local and national codes.

The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.

SFP+ Transceiver Specifications

The Cisco MDS 9250i switch is compatible with SFP+ transceivers and cables that have LC connectors. The wavelength of each transceiver must match the transceiver on the other end of the cable, and the cable must not exceed the stipulated cable length for reliable communications.

Cisco SFP+ transceivers provide the uplink interfaces, laser transmit (TX) and laser receive (RX), and support 850 to 1610 nm nominal wavelengths, depending upon the transceiver.

Use only Cisco SFP+ transceivers on the Cisco MDS 9250i switches. Each Cisco SFP+ transceiver is encoded with model information that enables the switch to verify that the SFP+ transceiver meets the requirements for the switch.
