If auto-negotiate is not used, 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. For more information about supported distances, see Table 4-8 on page 189. The OSA-Express5S feature is installed in the PCIe I/O drawer. The following  OSA-Express5S features can be installed on z14 servers (carry forward only): The OSA-Express5S features are listed in Table 4-5 on page 169. The OSA-Express5S 10 GbE LR feature (FC 0415) includes one PCIe adapter and one port  per feature. On z15, the port supports CHPID type OSD.  The 10 GbE feature is designed to support attachment to a single-mode fiber 10 Gbps  Ethernet LAN or Ethernet switch that is capable of 10 Gbps. The port can be defined as a  spanned channel and shared among LPARs within and across logical channel subsystems.  The OSA-Express5S 10 GbE LR feature supports the use of an industry-standard small form  factor LC Duplex connector. Ensure that the attaching or downstream device includes an LR  transceiver. The transceivers at both ends must be the same (LR-to-LR).  The OSA-Express5S 10 GbE LR feature does not support auto-negotiation to any other  speed and runs in full duplex mode only.  A 9  µmsingle-mode fiber optic cable that ends with an LC Duplex connector is required for  connecting this feature to the selected device.  For supported distances, see Table 4-8 on page 189. The OSA-Express5S 10 GbE SR feature (FC 0416) includes one PCIe adapter and one port  per feature. On z15, the port supports CHPID type OSD.  The 10 GbE feature is designed to support attachment to a multimode fiber 10 Gbps Ethernet  LAN or Ethernet switch that is capable of 10 Gbps. The port can be defined as a spanned  channel and shared among LPARs within and across logical channel subsystems.  The OSA-Express5S 10 GbE SR feature supports the use of an industry standard small form  factor LC Duplex connector. Ensure that the attaching or downstream device includes an SR  transceiver. The sending and receiving transceivers must be the same (SR-to-SR).  The OSA-Express5S 10 GbE SR feature does not support auto-negotiation to any other  speed and runs in full duplex mode only.  A 50 or a 62.5  µm  multimode fiber optic cable that ends with an LC Duplex connector is  required for connecting each port on this feature to the selected device. For more information about supported distances, see Table 4-8 on page 189.
