Osa-Express4S Features - IBM z13s Technical Manual

OSA-Express5S Gigabit Ethernet SX (FC 0414)
The OSA-Express5S Gigabit Ethernet (GbE) short wavelength (SX) feature has one PCIe
adapter and two ports. The two ports share a channel path identifier (CHPID type OSD
exclusively). The ports support attachment to a 1 Gbps Ethernet LAN. Each port can be
defined as a spanned channel and can be shared among LPARs and across logical channel
subsystems.
The OSA-Express5S GbE SX feature supports the use of an LC Duplex connector. Ensure
that the attaching or downstream device has an SX transceiver. The sending and receiving
transceivers must be the same (SX to SX).
A multi-mode fiber optic cable that terminates with an LC Duplex connector is required for
connecting each port on this feature to the selected device.
OSA-Express5S 1000BASE-T Ethernet feature (FC 0417)
Feature code 0417 occupies one slot in the PCIe I/O drawer. It has two ports that connect to
a 1000 Mbps (1 Gbps) or 100 Mbps Ethernet LAN. Each port has an SFP with an RJ-45
receptacle for cabling to an Ethernet switch. The RJ-45 receptacle is required to be attached
by using an EIA/TIA Category 5 or Category 6 unshielded twisted pair (UTP) cable with a
maximum length of 100 m (328 ft.). The SFP allows a concurrent repair or replace action.
The OSA-Express5S 1000BASE-T Ethernet feature supports auto-negotiation when attached
to an Ethernet router or switch. If you allow the LAN speed and duplex mode to default to
auto-negotiation, the OSA-Express port and the attached router or switch auto-negotiate the
LAN speed and duplex mode settings between them. They then connect at the highest
common performance speed and duplex mode of interoperation. If the attached Ethernet
router or switch does not support auto-negotiation, the OSA-Express port examines the
signal that it is receiving and connects at the speed and duplex mode of the device at the
other end of the cable.
The OSA-Express5S 1000BASE-T Ethernet feature can be configured as CHPID type OSC,
OSD, OSE, OSM, or OSN. Non-QDIO operation mode requires CHPID type OSE. When
defined as CHPID type OSM, the port provides connectivity to the intranode management
network (INMN).
The following settings are supported on the OSA-Express5S 1000BASE-T Ethernet feature
port:
Auto-negotiate
100 Mbps half-duplex or full-duplex
1000 Mbps full-duplex
If you are not using auto-negotiate, the OSA-Express port attempts to join the LAN at the
specified speed and duplex mode. If this specified speed and duplex mode do not match the
speed and duplex mode of the signal on the cable, the OSA-Express port does not connect.
