PCIe2 FH 4-Port 8 Gb Fibre Channel Adapter (FC 5729; CCIN 5729)

Overview

The PCIe2 FH 4-Port 8 Gb Fibre Channel Adapter (FC 5729) is a high-performance adapter based on the Emulex LPe12004 PCIe Host Bus Adapter (HBA). FC 5729 is a generation-2 adapter and is supported on systems that support the generation-2 adapters. The adapter provides four Fibre Channel ports. Each Fibre Channel port provides single initiator capability over a fibre link. The ports have LC type connectors and use shortwave laser optics. The adapter connects to Fibre Channel switches and operates at link speeds of 2, 4, and 8 Gbps. The adapter automatically negotiates with the switch to the highest speed of which the switch is capable. LEDs on each port provide information about the status and link speed of the port.

The following figure shows the FC 5729 adapter.

Cables

Cables are the responsibility of the customer. Use multimode fibre optic cables with short-wave lasers that adhere to the following specifications:

• OM3: Multimode 50/125 micron fibre, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron fibre, 500 MHz x km bandwidth
• OM1: Multimode 62.5/125 micron fibre, 200 MHz x km bandwidth

Because core sizes are different, only OM1 cables can be connected to other OM1 cables. For best results, do not connect OM2 cables to OM3 cables. However, if an OM2 cable is connected to an OM3 cable, the characteristics of the OM2 cable applies to the entire length of the cables.

The following table shows the supported distances for the three different cable types at the three different link speeds.

Table 1. Supported cable distances by link speed

Cable type	2.125 Gbps	4.25 Gbps	8.5 Gbps
OM3	0.5 m - 500 m	0.5 m - 380 m	0.5 m - 150 m
OM2	0.5 m - 300 m	0.5 m -150 m	0.5 m - 50 m
OM1	0.5 m - 150 m	0.5 m - 70 m	0.5 m - 21 m

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. To check for the prerequisites, see IBM Prerequisite website.

Adapter LED

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 the link rate conditions. There is a one second pause when the LED is off between each group of fast flashes (2, 3, or 4). Observe the LED sequence for several seconds to be sure that you have correctly identified the state.

Power-on self test (POST) conditions and results are summarized in Table 3. These states can be used to identify abnormal states or problems. Follow the action to be taken for each condition.

Replacing Fibre Channel adapters using hot swap

When hot swapping Fibre Channel adapters, be aware that device-related software for the storage devices might have additional devices (for example, the dar device associated with the FAStT or DS4800) that need to be removed. Refer to specific storage device documentation for information about how to remove these additional devices.

The adapter has a unique worldwide port name (WWPN). Check the zoning and LUN assignments to ensure that the new adapter functions as expected.
