PCIe LP 4 Gb 2-Port Fibre Channel Adapter (FC EL09; CCIN 5774)
Learn about the specifications and operating system requirements for the feature code (FC) EL09 adapter.
Overview
The PCIe LP 4 Gb 2-Port Fibre Channel adapter is a 64 bit, short form factor x4, PCIe adapter with an LC-type external fiber connector that provides single initiator capability over an optical fiber link or loop. The adapter automatically negotiates the highest data rate between the adapter and an attaching device at 1 Gbps, 2 Gbps, or 4 Gbps of which the device or switch is capable. Distances between the adapter and an attaching device or switch can reach up to 500 meters running at 1 Gbps data rate, up to 300 meters running at 2 Gbps data rate, and up to 150 meters running at 4 Gbps data rate. When used with IBM® Fibre Channel storage switches supporting longwave optics, the adapter can reach distances of up to 10 kilometers running at either 1 Gbps, 2 Gbps, or 4 Gbps data rates.
The adapter can be used to attach devices either directly, or with Fibre Channel switches. If you are attaching a device or switch with an SC type fiber connector, you must use an LC-SC 50 micron fiber converter cable (FC 2456) or an LC-SC 62.5 micron fiber converter cable (FC 2459).

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 1 summarizes normal LED states. There is a 1 Hz pause when the LED is off between each group of fast flashes (1, 2 or 3). Observe the LED sequence for several seconds to ensure that you correctly identify the state.
| Green LED | Yellow LED | State |
|---|---|---|
| On | 1 fast flash | 1 Gbps link rate - normal, link active |
| On | 2 fast flashes | 2 Gbps link rate - normal, link active |
| On | 3 fast flashes | 4 Gbps link rate - normal, link active |
Power-On Self Test (POST) conditions and results are summarized in Table 2. These states can be used to identify abnormal states or problems. Follow the action to be taken for each condition.
| Green LED | Yellow LED | State | Action to be taken |
|---|---|---|---|
| Off | Off | Wake-up failure (dead board) | Perform AIX®, IBM i, or Linux operating system diagnostics procedure. |
| Off | On | POST failure (dead board) | Perform AIX, IBM i, or Linux operating system diagnostics procedure. |

Device ID jumper
The default setting for the two device ID jumpers labeled P0_JX and P1_JX is to set the jumpers on pins 1 and 2 as shown in Figure 2. Do not change the jumper settings for a standard installation.
Replacing hot swap HBAs
Fibre Channel host bus adapters (HBAs) connected to a fiber array storage technology (FAStT) or DS4000® storage subsystem have a child device that is called a disk array router (dar). You must unconfigure the disk array router before you can hot swap an HBA that is connected to a FAStT or DS4000 storage subsystem. For instructions, see Replacing hot swap HBAs in the IBM System Storage® DS4000 Storage Manager Version 9, Installation and Support Guide for AIX, HP-UX, Solaris, and Linux on Power Systems™ Servers, order number GC26-7848.
