Upgrading T0569: Sequence for Downloading the ServerNet II Switch
Firmware and Configuration
Table 4-33 shows the sequence for upgrading the T0569 firmware and configuration.
Values shown in the table are relative. For example, if the running firmware is
T0569AAA and the running configuration is T0569AAB, see the column for old
firmware and a new configuration.
Table 4-9 on page 4-12 shows how SCF and TSM display the T0569AAA and
T0569AAB firmware and configuration.
This combination Is required for . . . And recommended for . . .
T0569AAA firmware and
T0569AAA configuration

eight nodes when at least one of
the nodes connected to the
cluster switches does not have
the T0502AAA or a superseding
SPR installed
T0569AAB firmware and
T0569AAB configuration
A split-star topology having
up to 16 nodes
All topologies when all of the
nodes connected to the cluster
switch have at least the
T0502AAA or a superseding
installed
T0569AAE firmware and
T0569AAE configuration
A tri-star topology having up
to 24 nodes
All topologies if T0502AAG is
