Refer to the exhibit. Which item does A represent?

An Emulex Adapter Card is a mezzanine-style network adapter, not the mLOM slot or its installed module.

A Virtual Interface Card (VIC) is a specific Cisco adapter product that may install in the mLOM or mezzanine slot, but the component labeled A represents the mLOM slot itself.

The mLOM (modular LAN-on-Motherboard) is a dedicated expansion slot on UCS blade servers that provides network interface card functionality directly integrated into the motherboard's LOM position. On the B420 M3, the mLOM slot accepts compatible mLOM adapters and offers connectivity without consuming a standard mezzanine expansion slot.

A Virtual Emulex Adapter Card is not a standard Cisco UCS product category and does not correspond to any labeled component on the B420 M3.

The SuperCap module is a flash-backed write cache power module for storage controllers, physically distinct from the mLOM slot location.
