spanned channel, and can be shared among LPARs within and across logical channel
subsystems.
The OSA-Express4S 10 GbE SR feature supports the use of an industry standard small form
factor LC Duplex connector. Ensure that the attaching or downstream device has an SR
transceiver. The sending and receiving transceivers must be the same (SR to SR).
The OSA-Express4S 10 GbE SR feature does not support auto-negotiation to any other
speed and runs in full duplex mode only. OSA-Express4S 10 GbE SR supports 64B/66B
encoding. However, the GbE supports 8B/10 encoding, making auto-negotiation to any other
speed impossible.
A 50 or a 62.5-µm multimode fiber optic cable that terminates with an LC Duplex connector is
required for connecting each port on this feature to the selected device.
OSA-Express4S Gigabit Ethernet LX (FC 0404)
The OSA-Express4S GbE LX 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-Express4S GbE LX feature supports the use of an LC Duplex connector. Ensure
that the attaching or downstream device has an LX transceiver. The sending and receiving
transceivers must be the same (LX to LX).
A 9-µm single mode fiber optic cable that terminates with an LC Duplex connector is required
for connecting each port on this feature to the selected device. If multimode fiber optic cables
are being reused, a pair of Mode Conditioning Patch cables is required, one for each end of
the link.
OSA-Express4S Gigabit Ethernet SX (FC 0405)
The OSA-Express4S Gigabit Ethernet (GbE) 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-Express4S 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 50 or a 62.5-µm multimode fiber optic cable that terminates with an LC Duplex connector is
required for connecting each port on this feature to the selected device.
OSA-Express4S 1000BASE-T Ethernet feature (FC 0408)
The OSA-Express4S 1000BASE-T Ethernet feature occupies one slot in the PCIe I/O drawer.
It has two ports that connect to a 1000 Mbps (1 Gbps), 100 Mbps, or 10 Mbps Ethernet LAN.
Each port has an RJ-45 receptacle for cabling to an Ethernet switch. The RJ-45 receptacle
must be attached by using an EIA/TIA Category 5 or Category 6 UTP cable with a maximum
length of 100 meters (328 ft).
