IBM Power System E850C: Technical Overview and Introduction
Table 2-27 shows the available media device feature codes for the Power E850C server.

2.11 External I/O subsystems
This section describes the PCIe Gen3 I/O expansion drawer that can be attached to the
Power E850C server.
2.11.1 PCIe Gen3 I/O expansion drawer
PCIe Gen3 I/O Expansion drawers (#EMX0) can be attached to the system unit to expand the
number of full-high, hot-swap Gen3 slots available to the server. The maximum number of
PCIe Gen3 I/O drawers depends on the number of processor modules physically installed.
The maximum is independent of the number of processor core activations.
The PCIe Gen3 I/O expansion drawer is a 4U high, PCI Gen3-based and 19-inch rack
mountable I/O drawer. It offers two PCIe Fan Out Modules (#EMXF), each of which provides
six full-length, full-height PCIe slots that are labeled C1 through C6. Slots C1 and C4 are x16
slots, and C2, C3, C5, and C6 are x8 slots. Slots C1 and C4 of the 6-slot fanout module in a
PCIe Gen3 I/O drawer are SR-IOV enabled.
An #EMX0 drawer can be configured with one or two EMXF fanout modules. Adding a second
fanout module is not a hot-plug operation and requires scheduled downtime.
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 (#EJ08) and two 3.0 m (#ECC7), or two
10.0 m (#ECC8) CXP 16X Active Optical cables (AOC) connect the system node to a PCIe
Fan Out module in the I/O expansion drawer. One feature #ECC7, or one #ECC8 ships two
AOC cables.
Concurrent repair and add or removal of PCIe adapters is done by HMC guided menus or by
operating system support utilities.
A blind swap cassette (BSC) is used to house the full high adapters that go into these slots.
The BSC is the same BSC as used with the previous generation server’s
#5802/5803/5877/5873 12X attached I/O drawers.
A maximum of four PCIe Gen3 I/O drawers can be attached to the Power E850C server, if
equipped with four processor modules. The maximum number of PCIe Gen3 I/O drawers
depends on the number of installed processor modules. Table 2-28 on page 63 lists the
maximum PCIe Gen3 I/O drawer configurations for the Power E850C server.
