You can configure the console controller auxiliary port to support a UPS. See
Chapter 3, “Configuring Serial Ports for Terminals and Modems,” in the HP-UX
Operating System: Peripherals Configuration (R1001H) for more information.
Managing Flash Cards
Continuum Series 400/400-CO systems use a device called a flash card to perform
the primary boot functions. The flash card contains the primary bootloader, a
configuration file, and the secondary bootloader. The HP-UX operating system
kernel is stored on the root disk and booted from there.
NOTE
Properly maintaining your flash cards is critical for achieving
continuous availability. Make sure that you understand and follow all
the instructions described in this section.
Each PCI bridge card has a slot for a 20-MB PCMCIA flash card. (Continuum Series
400/400-CO systems include a PCI bridge card in the first slot of each card-cage.)
Only one flash card is required to boot the system, and you can boot the system
from either card-cage.
NOTE
Stratus recommends that you keep flash cards in both card-cages at all
times to provide a backup should the primary card fail and, if
appropriate in your environment, set the write protect tab so the data on
the backup flash card is protected.
A flash card contains three sections, as shown in Figure 3-2. The first is the label,
the second is the primary bootloader, and the third is the LIF.
