Servicing a Blade Server
Memory Mirroring and RAS
The Intel CPUs within the blade server support memory mirroring only when an even number of Channels
are populated with DIMMs. If one or three channels are populated with DIMMs, memory mirroring is
automatically disabled. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for
reasons of reliability.
Installing an mLOM Adapter
The Cisco VIC 1340 and VIC 1240 are specialized modular LAN on Motherboard (mLOM) adapters that
provide dual 2 x 10 Gb of Ethernet/ or Fiber Channel over Ethernet (FCoE) connectivity to each chassis. They
plug into the dedicated mLOM connector only, and they are the only adapters that can be plugged into the
mLOM connector. They provide connectivity through Cisco UCS 6100 and 6200 Series Fabric Interconnects.
The Cisco VIC 1200 Series (1240 and 1280) is compatible in UCS domains that implement both UCS 6100
and 6200 Series Fabric Interconnects. However, the Cisco VIC 1300 Series (1340 and 1380) is compatible
only with the UCS 6200 Series Fabric Interconnects.
Note
You must remove the adapter card to service it.
To install a Cisco VIC 1240 or VIC 1340 in the blade server, follow these steps:
Procedure
Step 1
Position the VIC board connector above the motherboard connector and align the captive screw to the standoff
post on the motherboard.
Step 2
Firmly press the VIC board connector into the motherboard connector.
Step 3
Tighten the captive screw.
