CAUTION:
CoreBuilder
9000 software Release 3.0 requires that the
Enterprise Management Engine (EME) have 20 MB of CPU RAM. To
determine the CPU RAM size, enter
show eme
from the EME command
line interface. The
CPU Ram Size(MB)
field on the left side of the screen
indicates the amount of CPU RAM:
8
or
20
.
If your EME has 8 MB of CPU RAM, you must replace the 4 MB DRAM
card in your EME with a 16 MB DRAM card. Contact your network
supplier or 3Com representative for information about how to obtain a
16 MB DRAM memory card.
CAUTION:
Except for the Enterprise Management Controller (EMC) boot
file,
you must upgrade all the modules in the CoreBuilder 9000 chassis,
including the EME module, to major software Release 3.0. You cannot
run Release 3.0 software on some modules and not on other modules.
See Table 1 in this chapter for more information about the software
version that each CoreBuilder 9000 component requires.
The EMC boot file remains at software Release 2.1.0.
