Figure 16 Dual I/O Module Stacks (Fabric B)
Single I/O Module Stack
All of the I/O modules in each of the enclosures can be stacked together as shown in Figure 17 below.
This provides a single management structure for the blade I/O modules. This configuration scales the
number of M1000e blade enclosures to ½ of the number allowed in the Dual Stack configuration. For
Cisco Catalyst 3130 family of I/O modules, the enclosure limit would be 4 M1000e’s, and for the
PowerConnect M6220 I/O modules, the enclosure limit would be 5 M1000e’s. This configuration is not a
preferred method for stacking M1000e blade enclosures. See the Dual I/O Module Stack in the previous
section for the preferred method of stacking.
