NOTE: The Virtual Media speed on an interface adapter that also supports smart cards is only Full-Speed (approximately 6x CD-ROM). To use Hi-Speed Virtual Media (approximately 12x CD-ROM), you must use a Virtual Media only interface adapter. For configurations to work properly, you must have an interface adapter with Virtual Media connecting each server to the console switch. For more information, see Using Virtual Media (on page 60).

Cascading console switches

Cascading console switches overview

The G2 console switches support two levels of cascading or tiering devices. You can cascade multiple

console switches to increase the number of devices available from a single access point.

When cascading console switches with Virtual Media, verify the following:

•

Interface adapters are not be used to cascade console switches. If interface adapters are used to

cascade console switches, you do not have seamless integration, and you lose Virtual Media support.

Use interface adapters with Virtual Media capability if you require Virtual Media.

•

All cascaded console switches and interface adapters must have the most current firmware. To upgrade

console switch firmware, see Upgrading the firmware.

Cascading console switches matrix

General rules of cascading console switches include:

•

You can either cascade a newer console switch over an older console switch, or cascade switches of the

same generation. An older console switch cannot be the primary console switch over a newer

secondary switch.

•

IP console switches cannot be cascaded under other IP console switches.

•

In order for a particular feature to function, such as Virtual Media, all console switches and interface

adapters in the cascade must support the feature.

NOTE:

The Virtual Media speed on an interface adapter that also supports smart cards is only

Full-Speed (approximately 6x CD-ROM). To use Hi-Speed Virtual Media (approximately 12x

CD-ROM), you must use a Virtual Media only interface adapter.

For configurations to work properly, you must have an interface adapter with Virtual Media connecting each

server to the console switch. For more information, see Using Virtual Media (on page

HP Server Console Switches and Compaq Server Console Switches are not Virtual Media capable and

cannot be used as a primary console switch over any of the Virtual Media capable console switches.

The following table shows several two-level cascade configurations.
