4.3 Powering Up
The initial powering up can be done by connecting a terminal to the front
panel serial I/O interface A. The advantage of using a terminal is that you
do not need any frame buffer, monitor, or keyboard for initial powering
up.
Booting The SPARC/CPCI-52x(G) boot PROM consists of a 1 MByte PROM
(OTP) PLCC socket device (not writeable). Alternatively a 2 MByte
TSOP boot flash EPROM device can be enabled by SW6-2. This boot
flash EPROM device is writeable if enabled by SW4-3.
Note: If you have an unformatted floppy disk in a floppy connected
to your SPARC/CPCI-52x(G) then the OpenBoot does not come up.
Per default the SPARC/CPCI-52x(G) is shipped with its boot PROM
containing the OpenBoot firmware (see section 4.8 “OpenBoot Firm-
ware” on page 42).
