CH221 mezzanine cards

The CH221 mainboard provides two mezzanine card connectors. However, only the upper mezzanine card can be installed. The mezzanine card connects to the E9000 midplane to communicate with the switch and pass-through modules in slots 2X and 3X. Socket CPU1 provides PCIe x16 bandwidth for connecting to Mezz2. The CH221 supports expansion of GE, 10GE, 40GE, 8G FC, or 16G FC ports through mezzanine cards.
