Cable and Port Specifications

This appendix includes information about the cables and connectors used with the Cisco MDS 9148T Multilayer Fabric Switch.

Caution

We strongly recommend that power cable runs and other potential noise sources be located as far away as practical from network cabling that terminates at Cisco equipment. In situations where long parallel cable runs exist, but cannot be separated by at least 3.3 ft. (1 m), we recommend that you shield these potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded metallic conduit.

Cables and Adapters

The Accessory kit includes the following:

RJ-45-to-RJ-45 rollover cable
RJ-45-to-DB-9 female DTE adapter (labeled Terminal)
RJ-45-to-DB-25 female DTE adapter (labeled Terminal)
RJ-45-to-DB-25 male DCE adapter (labeled Modem)

Note

Additional cables and adapters can be ordered from your customer service representative.

Console Port

The console port is an asynchronous RS-232 serial port with an RJ-45 connector. You can use the RJ-45-to-RJ-45 rollover cable and the RJ-45-to-DB-9 female adapter or the RJ-45-to-DB-25 female DTE adapter (depending on your computer serial port) to connect the console port to a computer running terminal emulation software.

Supported Power Cords and Plugs

Each switch power supply unit requires one power cord. Cisco approved cords may be ordered with the product. Standard power cords with a country specific plug can be used with wall outlets. Jumper power cords can be used with cabinet outlets. The user may also source their own power cords for the product, as long as they meet the power cord specifications for this product.

Note

Only the standard power cords or jumper power cords ordered from Cisco are supported.
Not all cables are compatible with the locking mechanism.

Caution

If you do not order a power cord with the system, you are responsible for selecting the appropriate power cord for the product. Using a noncompatible power cord with this product may result in electrical safety hazard. Orders delivered to Argentina, Brazil, and Japan must have the appropriate power cord ordered with the system.

Standard Power Cords

Cisco standard power cords for the switch have an IEC C15 connector on the outlet end of the cord and a country specific plug on the inlet end of the cord.
