Chapter 4. Central processor complex I/O system structure 167
defined as CHPID type OSX, the 10 GbE port provides connectivity and access control to the
intraensemble data network (IEDN) from z13s servers to z BladeCenter Extension (zBX). 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 can be 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 has an LR
transceiver. The transceivers at both ends must be the same (LR to LR, which might also be
referred to as LW or LX).
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
µm single-mode fiber optic cable that terminates with an LC Duplex connector is required
for connecting this feature to the selected device.
OSA-Express5S 10 Gigabit Ethernet SR (FC 0416)
The OSA-Express5S 10 Gigabit Ethernet (GbE) Short Reach (SR) feature has one PCIe
adapter and one port per feature. The port supports CHPID types OSD and OSX. When
defined as CHPID type OSX, the 10 GbE port provides connectivity and access control to the
IEDN from z13s servers to zBX. 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 can be 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 has an SR
transceiver. The sending and receiving transceivers must be the same (SR to SR, which
might also be referred to as SW or SX).
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 terminates with an LC Duplex connector is
required for connecting each port on this feature to the selected device.
OSA-Express5S Gigabit Ethernet LX (FC 0413)
The OSA-Express5S Gigabit Ethernet (GbE) long wavelength (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-Express5S 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, with one cable for
each end of the link.
