Installation Information
Consider the following points when installing the AD278A/AD279A PCI MUX product:
• Install the AD278A/AD279A PCI MUX hardware when the system is down.
• Install the AD278A/AD279A PCI MUX driver software before installing the MUX cards, to
avoid a second reboot.
• The kernel dynamically assigns the major number for the PCI MUX when you install the
AD278A/AD279A PCI MUX driver.
This major number can differ from system to system. However, once a major number is
assigned, it remains unchanged across reboots until the driver is removed. To find the major
number, run the following command at the command prompt:
$ lsdev -d pci_mux1
The name of the AD278A/AD279A PCI MUX adapter driver is pci_mux1. For more
information about installation, see the HP AD278A/AD279A PCI 8-Port Serial Multiplexer
Installation Guide or the HP AD278A/AD279A PCI 64-Port Serial Multiplexer Installation Guide.
