PCIe3 16 Gb 2-port Fibre Channel Adapter (FC EN0A; CCIN 577F)
Learn about the specifications and operating system requirements for the feature code (FC) EN0A adapter.
Overview
The PCIe3 16 Gb 2-port Fibre Channel Adapter is an x8, generation 3, PCIe adapter. This adapter is a high-performance 8x short form adapter also referred to as a PCIe Host Bus Adapter (HBA). The adapter provides two ports of 16 Gb Fibre Channel capability using 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 little connector-type (LC) and utilize shortwave laser optics. The adapter operates at link speeds of 4, 8 and 16 Gbps and will automatically negotiate to the highest speed possible. LEDs on each port provide information on the status and link speed of the port.
The adapter connects to a Fibre Channel switch at 4 Gb, 8 Gb or 16 Gb. It can directly attach to a device without a switch at 16 Gb. Attachment without a switch is not supported at 4 Gb or 8 Gb.
N_Port ID Virtualization (NPIV) capability is supported through VIOS.

Adapter LED states
Green and yellow LEDs can be seen through openings in the mounting bracket of the adapter. Green indicates firmware operation, and yellow signifies port activity. Table 2 summarizes normal LED states. A 1 Hz pause occurs when the LED is off between each group of fast flashes (2, 3 or 4). Observe the LED sequence for several seconds to ensure that you correctly identify the state.
Green LED | Yellow LED | State |
---|---|---|
On | 2 fast flashes | 4 Gbps link rate: normal, link active |
On | 3 fast flashes | 8 Gbps link rate: normal, link active |
On | 4 fast flashes | 16 Gbps link rate: normal, link active |
Power-on-self-test (POST) conditions and results are summarized in Table 3. These states can be used to identify abnormal states or problems.
