Network express modules (NEMs) offer systemic connectivity to the blades in the chassis. Each NEM connects to all 10 blade slots. The basic NEM provides a 10/100/1000 Ethernet connection for each blade. Other NEMs can provide SAS-1 or SAS-2 connectivity to disk blades and 10GbE Ethernet ports, in addition to the 10/100/1000 Ethernet connection for each blade.
The chassis provides two NEM slots. Adding a second NEM provides a second set of 10/100/1000 Ethernet connections for each blade. For NEMs with SAS connectivity, adding a second NEM provides a redundant connection to SAS disks.
Note - If there is no NEM in the chassis, a PCIe EM can be used to provide server blades with Ethernet connectivity. See PCIe EMs for information about PCIe EMs.
Most NEMs are hot-swappable or hot-pluggable.
You can remove and replace hot-swappable components without shutting down any system component.
You can remove hot-pluggable components without shutting down the system; however, administrators must prepare the system first. Usually this requires idling or turning off the component to be hot plugged.
The type of connectivity depends on the NEM.
Note - Most NEM functions, other than the 10/100/1000 Ethernet port, require a matching REM or FEM mounted on the blade motherboard before the blade server can use that function. See RAID Expansion Modules or Fabric Expansion Modules for more information.
The following table shows the supported NEMs and links to available NEM documentation. The NEMs listed here were available at the time this topic set was last updated.
