PCIe3 x8 2-port Fibre Channel Adapter (16 Gb/s); (FC EN1G and EN1H; CCIN 579B)

Learn about the specifications and operating system requirements for the feature code (FC) EN1G and EN1H adapters.

Overview

The FC EN1G and EN1H are electronically identical. FC EN1G is a full-height adapter and FC EN1H is a low-profile adapter.

The PCIe3 x8 dual-port Fibre Channel (16 Gb/s) adapter is a PCI Express (PCIe) generation 3 (Gen3) x8 adapter. This PCIe adapter is based on the Marvell QLE2692 PCIe host bus adapter 15.2 cm x 7 cm (6.6 inches x 2.7 inches). The adapter provides two ports of 16 Gb Fibre Channel capability by using SR optics. Each port can provide up to 16 Gb fibre channel functions simultaneously. Each port provides single initiator capability over a fiber optic link or with N_Port ID Virtualization (NPIV) it provides multiple initiator capabilities. The ports are small form-factor pluggable (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 it automatically negotiates to the highest speed possible. The adapter can be started on IBM Power Systems with FCode.

Cables

Use multimode fiber optic cables with shortwave lasers that adhere to the following specifications:
  • OM4: Multimode 50/125 micron fiber, 4700 MHz x km bandwidth
  • 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 be connected only to other OM1 cables. For best results, OM2 cables must not be connected to OM3 or OM4 cables. However, if an OM2 cable is connected to an OM3 or OM4 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 OM4
4 Gbps 0.5 meters to 70 meters (1.64 feet to 229.69 feet) 0.5 meters to 150 meters (1.64 feet to 492.12 feet) 0.5 meters to 380 meters (1.64 feet to 1246.72 feet) 0.5 meters to 400 meters (1.64 feet to 1312.34 feet)
8 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) 0.5 meters to 190 meters (1.64 feet to 623.26 feet)
16 Gbps   0.5 meters to 35 meters (1.64 feet to 114.82 feet) 0.5 meters to 100 meters (1.64 feet to 328.08 feet) 0.5 meters to 125 meters (1.64 feet to 410.10 feet)
Note: The hardware cannot detect the type and length of cable that is installed. The link auto-negotiates to the speed that is reported during negotiation by the system. You must manually set the maximum value for speed that can be set during negotiation. If you set a value for speed that is higher than the supported cable value, errors can occur.

Adapter LED

Green LEDs can be seen through openings in the mounting bracket of the adapter. Table 2 summarizes the LED states for this adapter.
