2: System Management
Chassis Manager Interconnects
The chassis manager in each blade enclosure connects to the system administration, rack leader
and service node servers via Gigabit Ethernet switches. See the example in Figure 2-2.
Use of a CDU is required in all E-Cell configurations as of the time of publication of this
document. The VLAN3 interface allows the CMCs to monitor and adjust the activity of the
cooling racks in an E-Cell as well as the external cooling distribution unit (CDU). The CDU rack
supplies liquid cooling to the individual blades within the E-racks.
