M-rack Chassis Manager Interconnection

007-5806-004
Note that the non-redundant example (shown in Figure 2-3) is a non-standard chassis management
configuration with only a single virtual local area network (VLAN) connect line from each CMC
to the internal LAN switch. See also "Multiple Chassis Manager Connections" in Chapter 3.

The interconnection of an M-Cell's rack environment is somewhat more complex than a D-rack
and requires the use of a third VLAN (VLAN3) within the Gigabit Ethernet switch network.
This VLAN3 interface allows the CMCs to monitor and adjust the activity of the cooling racks in
an M-cell as well as the external cooling distribution unit (CDU). The CDU rack supplies cooling
to the individual blades within the M-rack.
Figure 2-4 on page 22 shows a block diagram example of the interconnection scheme for an
M-Cell rack.
