It is also important to note that several daily functions where a DVD drive was needed can
now be executed by using other methods like Virtual Media Repository on the Virtual I/O
Server or the Remote Virtual I/O Server install on HMC.

2.9 External I/O subsystems

This section describes the PCIe Gen3 I/O expansion drawer that can be attached to the
Power E870 and Power E880.

2.9.1 PCIe Gen3 I/O expansion drawer

The PCIe Gen3 I/O expansion drawer is a 4U high, PCI Gen3-based and rack mountable I/O
drawer. It offers two PCIe FanOut Modules (#EMXF) that each provide six PCIe slots.
The physical dimensions of the drawer are 444.5 mm (17.5 in.) wide by 177.8 mm (7.0 in.)
high by 736.6 mm (29.0 in.) deep for use in a 19-inch rack.
A PCIe x16 to Optical CXP converter adapter (#EJ07) and 2.0 M (#ECC6) or 10.0 M (#ECC8)
CXP 16X Active Optical cables (AOC) connect the system node to a PCIe FanOut module in
the I/O expansion drawer. One feature #ECC6 or one #ECC8 ships two AOC cables.
