PCIe2 LP 8 Gb 4-port Fibre Channel Adapter (FC EN0Y; CCIN EN0Y)

Learn about the specifications and operating system requirements for the feature code (FC) EN0Y adapter.

Overview

The PCIe2 LP 8 Gb 4-port Fibre Channel Adapter is a PCI Express (PCIe) generation-2, low-profile, high-performance, x8 short form factor plus (SFF+) Host Bus Adapter (HBA). This adapter enables multiple logical (virtual) connections to share the same physical port. Each logical connection has its own resources and the ability to be managed independently. Each port provides single initiator capability over a fiber link or provides multiple initiator capability with N_Port ID Virtualization (NPIV). The ports are connected by using LC type connectors. These connectors use shortwave laser optics. The adapter operates at link speeds of 2, 4, and 8 gigabits per second (Gbps) and automatically negotiates to the highest speed possible. LEDs on each port provide information about the connection status and link speed of the port. The adapter connects to a Fibre Channel switch.

The LEDs on the adapter indicate the TX/RX and link status as shown in Table 1.

Figure 1 shows the adapter.

Maximum number

For details about the maximum number of adapters that are supported, see PCIe adapter placement rules and slot priorities and select the system you are working on.

Attributes provided

NPIV capability is supported through VIOS.
Requires a PCI Express generation-2 x8 slot for all four ports to operate at full speed.

For details about slot priorities and placement rules, see PCIe adapter placement rules and slot priorities and select the system you are working on.

Cables

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 2. 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)
