Digital’s SRM Console Settings

When the ITI-5232E is being used in a Digital Alpha platform running OpenVMS or Digital UNIX, the SRM console is used to set the port speed, media (cable) type and boot protocols, and can also be used to test the module.

After powering your system up, and before booting your operating system, the system will stop at the SRM console prompt. On a uni-processor machine, the SRM prompt is “>>>” and on the primary processor of a multi-processor machine, is “P0>>>”.

Digital uses a set of “Environment Variables” to store the settings of certain user definable parameters, which are passed to the operating system to allow the users configuration information to stay consistent when the SRM passes control of the system to the operating system.

Displaying and Setting Ethernet Port Characteristics

The Alpha console recognizes the Ethernet device as an EW port. There are two commands that are necessary for setting and showing the Ethernet port:

SET and SHOW.

Use SHOW to display characteristics of the Ethernet port.

>>>Show EWn0_MODE

Where ‘n’ is the Ethernet port letter.

Use SET to set characteristics of the Ethernet port. The available settings for Ethernet media type are shown in Table 4.
