Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/

PCIe3 x8 4-port Fibre Channel (16 Gb/s); (FC EL5W, EL5X, EN1C, and EN1D; CCIN 578E)
Learn about the specifications and operating system requirements for feature code (FCs) EL5W, EL5X,
EN1C, and EN1D (EL5X) adapters.
Overview
The FC EN1C (EL5W) and EN1D (EL5X) are electronically identical. FC EN1C (EL5W) is a full-height
adapter and FC EN1D (EL5X) is a low-profile adapter.
The PCIe3 x8 4-port fibre Channel (16 Gb/s) Adapter is a PCI Express (PCIe) generation 3 (Gen3) x8
adapter. The adapter can be used in either a x8 or x16 PCIe slot in the system. This adapter is a high-
performance is based on the Broadcom LPe31004-series PCIe host bus adapter (HBA). The adapter
provides four ports of 16 Gb Fibre Channel capability that uses SR optics. Each port can provide up to 16
Gb Fibre Channel functions simultaneously. Each port provides single initiator capability over a fibre link
or with NPIV, multiple initiator capability is provided. The ports are SFP+ and include an optical SR
transceiver. The ports have LC type connectors and use shortwave laser optics. The adapter operates at
link speeds of 4, 8, and 16 Gbps and automatically negotiates to the highest speed possible. Each port
has two LED indicators that are located on the bracket next to each connector. These LEDs communicate
boot status and give a visual indication of the operating state. The LEDs have five defined state; solid on,
solid off, slow blink, fast blink, and flashing. The slow blink rate is 1 Hz, the fast blink is 4 Hz, and the
flashing refers to an irregular on/off transition that reflects test progress. The operator should observe the
LED sequence for several seconds to ensure that the operating state is correctly identified.
