System Modules
The following sections contain information about Dell EMC PowerEdge MX7000 system modules.
Management Module (MM)
The MX9002m Management Module (MM), or MM, essentially controls the overall chassis power, cooling, and physical user
interfaces such as the front panel. It also contains the Ethernet switch used by the management network (Fab-D) and external
Ethernet ports. MX7000 supports two MM for redundancy. At least one MM is required to power up the system.
External Network RJ-45 Ports
The MM internal network switch supports dual 1000BASE-T uplink ports to the chassis management network. The management
network provides Gigabit Ethernet (GbE) connectivity to a Sleds, and IOMs. Either uplink port may be used as a stacking port if
multiple MM are daisy-chained to networking switches.
External Micro USB Serial Port
The MX9002m Management Module (MM) provides a Micro-USB port for serial access by an external host. The UART settings are
115K baud, 8 data bits, 1 stop bit.
System ID Button
The System ID button on the MM rear panel allows for identifying the system in a rack. When pressed, the front panel of the chassis
will also blink in the identify pattern. This button also serves as the Health status LED indicator, displaying blue for health or blinking
amber if the MM has a fault.
The rear mounted ID button ONLY illuminates the Chassis/MM ID button, it does not step through the other devices like the Left
Control Panel ID Button.
Compute Sled
The MX7000 supports up to eight standard size or up to four double wide compute sleds. The MX7000 supports 14G Next-
Generation Modular (NGM) compute sleds but does not support 13G, FX2 or M1000e form-factor sleds.
Storage Sled
The MX7000 can accept a storage sled in the front slot, using the same form factor of a compute sled. The MX5016s is an example
of this type of sled. The storage sled shall use the Fab-C interconnect within the chassis to communicate with the IOMs.
NOTE: There is no pre-assigned mapping of a storage sled to a compute sled in the MX7000/MX5016s configuration.
User may map the entire storage sled to any compute sled, or map specific hard drives within the storage sleds to
different compute sleds.
