Compatible console switch models
Review the following information before cascading console switches with this product.
This product supports only one level of cascading. An expansion module is considered a level of
cascading and therefore cannot be used in combination with cascaded console switches.
To ensure optimum equipment performance while cascading console switches, follow the proper
powering-on sequence—power on the console switches, monitor, and then servers.
CAUTION: Do not use interface adapters to cascade console switches with console switches. If interface
adapters are used to cascade these products, undesirable operations might occur.
NOTE: The console switch does not support Compaq KVM PCI Cards or HP legacy console switches.
NOTE: To perform a firmware upgrade for a cascaded console switch and all attached interface adapters,
you must locally connect the keyboard, monitor, and mouse to the cascaded console switch to access the
local OSD.
Compaq Server Console Switch
CAUTION: While cascading a 2 x 8 Compaq Server Console Switch, connect only one Interface Adapter
at any given time. Undesirable operations might occur if multiple Interface Adapters are attached.
CAUTION: While cascading console switches, be sure that the Compaq Server Console Switch is
cascaded below the console switch. Undesirable operations might occur if these specific cascading
sequences are not followed.
The following Compaq Server Console Switches can be integrated into the console switch system.
Compatible Compaq Server Console Switch models include:
• 1 x 4 [PN: 400336 (-001)(-291)(B-31)]
• 1 x 8 [PN: 400337 (-001)(-291)(B-31)]
• 2 x 8 [PN: 400338 (-001)(-291)(B-31)]
• 2 x 8 48 VDC [PN: 400542 B-21]
All Compaq Server Console Switches must be upgraded with SoftPaq firmware, version 2.1.1. from the
Softpaq SP21898 directory or later, when cascaded with this product.
