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. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent

for reasons of reliability.

Installing a Virtual Interface Card Adapter

The Cisco Virtual Interface Card (VIC) 1340 and VIC 1240 are specialized adapters that provide dual 2 x 10

Gb of Ethernet or Fiber Channel over Ethernet (FCoE) connectivity to each blade server. They plug into the

dedicated VIC connector, and they are the only adapters that can be plugged into the slot 1 connector. They

provide connectivity through Cisco UCS 6100, 6200, and 6300 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. The Cisco VIC 1300 Series (1340 and 1380) is compatible with the UCS 6200 Series

Fabric Interconnects and UCS 6300 Series Fabric Interconnects.

Note

You must remove the adapter card to service it.

To install a Cisco VIC 1340 or VIC 1240 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.

Tip

To remove a VIC, reverse the above procedure. You might find it helpful when removing the

connector from the motherboard to gently rock the board along the length of the connector until it

loosens.
