PCIe 8 Gb 2-Port Fibre Channel adapter (FC 5273, FC 5735, FC EL2N, and FC EL58; CCIN 577D)

Overview

FC 5273 and FC EL2N are low-profile adapters. FC 5735 and FC EL58 are full-height adapters.

The PCIe 8 Gb 2-Port Fibre Channel adapter is a high-performance adapter based on the Emulex e12002 PCIe Host Bus Adapter (HBA). Each port provides single initiator capability over a fiber link. The ports have LC type connectors that use shortwave laser optics. The adapter connects to Fibre Channel switches and direct attached storage devices, operating at link speeds of 2, 4, and 8 Gbps. The adapter automatically negotiates with the switch to the highest speed that the switch is capable of. LEDs on each port provide information about the status and link speed of the port.

N_Port ID Virtualization (NPIV) capability is supported through Virtual I/O Server (VIOS).

Cables

Cables are the responsibility of the customer.

Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:

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

Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best results, OM2 cables should not be connected to OM3 cables. However, if an OM2 cable is connected to an OM3 cable, the characteristics of the OM2 cable apply to the entire length of the cables. The following table shows the supported distances for the different fiber optic cable types at different link speeds.

Table 1. Supported distances for multimode fiber optic cables

Header	Cable Type and Distance
Rate	OM1	OM2	OM3
2.125 Gbps	0.5 meters to 150 meters (1.64 feet to 492.12 feet)	0.5 meters to 300 meters (1.64 feet to 984.25 feet)	0.5 meters to 500 meters (1.64 feet to 1640.41 feet)
4.25 Gbps	0.5 meters to 70 meters (1.64 feet to 229.65 feet)	0.5 meters to 150 meters (1.64 feet to 492.12 feet)	0.5 meters to 380 meters (1.64 feet to 1246.71 feet)
8.5 Gbps	0.5 meters to 21 meters (1.64 feet to 68.89 feet)	0.5 meters to 50 meters (1.64 feet to 164.04 feet)	0.5 meters to 150 meters (1.64 feet to 492.12 feet)

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 1-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.

Replacing Fibre Channel adapters by using hot swap

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

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