Table 5–4: Adding a Memory Channel Interconnect or Rolling from a Dual,
Redundant MC1 Interconnect to MC2 Interconnects (cont.)
Step
Action Refer to:
Standard Hub Configuration:
Remove the MC1 adapter and install the MC2 adapter in
one system, and on one rail at a time. Use a BN39B-10
link cable to connect the new MC2 adapter to the linecard
in the MC2 hub that corresponds to the same linecard that
the MC1 module was connected to in the MC1 hub.
Figure 5–4, and
Figure 5–5
If this is the last system on this rail to receive an MC2
adapter (that is, all other member systems on this rail
have one MC2 adapter) you can replace both MC1 adapters
at the same time. Use a BN39B-10 link cable to connect
the new MC2 adapters to the linecard in their respective
MC2 hub that corresponds to the same linecard that the
MC1 modules were connected to in the MC1 hubs.

Turn on the system and run the mc_diag Memory Channel
diagnostic. Note that you cannot run mc_cable because
this is the only system in the cluster that is shut down.
Section 5.6
7
Boot the system.

Repeat steps 1 - 7 for all other systems in the cluster.
When you have replaced both MC1 adapters in the
last system, repeat steps 1 - 7 and replace the MC1
adapters on the other interconnect.

If desired, after the last member system has had its second
MC1 adapter replaced with an MC2 adapter, and the
cluster is operational, if all MC2 adapters are jumpered
for 512 MB (and you need to utilize 512 MB address space)
enable increasing the address space to 512 MB:
