Appendix A. Additional specifications

The following sections contain information about additional system specifications.

Population rules

System modules must be populated as described in the following table:
Table 12. MX7000 population rules
Category Maximum population
Blanks All the empty slots in the MX7000 enclosure must be populated with blanks (Sled, IOM, EC, and PSU). This is
required for proper cooling of the enclosure and components.
Fans All system fans must be populated in the enclosure.
Power supply The number of power supply units that are required is dependent upon system configuration and the required
units redundancy mode. The minimum quantity must be 2. For grid redundancy, power supply units must be
populated in the following order: 1, 4, 2, 5, 3, 6.
Power cable One C21/C20 power cable must be connected to the C22 plug corresponding to each populated PSU.
Management A Management module must be present to control and manage the enclosure.
module
NOTE: If a single Management module crashes, the system functions normally.
NOTE: The enclosure cannot be managed or controlled until the Management module is replaced.
Control panel The right control panel and one of the left control panel configurations (LCD or LED) must be present on the
MX7000 enclosure.
Compute sled Up to eight single-width or four double-width sleds or a combination can be populated. The double-width sleds
must be in slots 1, 3, 5, 7 due to the enclosures design.
Storage Sled
Up to seven Storage sleds can be populated in the enclosure.
NOTE: One compute node must be present and it must be mapped to a storage node.
One Fabric-C SAS IOM must be present and powered ON.
I/O Module Only Brocade and SAS IOM are supported in Fabric-C.
Only one type of IOM can be offered in Fabric-C (Fibre Channel or SAS IOM, not mixed).
Only one type of switch can be offered in Fabric-B (HPCC or Ethernet).
Two Fabric-C SAS IOMs must be installed if the enclosure contains a Storage Node.
Mix Speed of pass-through in same fabric is not enabled.
Mezzanine cards If the enclosure contains a storage node, Fabric-C MiniMezzanine card (HBA330 or Jumbo PERC) must be
installed in one compute node.
Dual Port or quad port mezzanine cards must be installed for redundant IOM/Pass-through configurations.
