Learn about the specifications and operating system requirements for the feature code (FC) EN0Y adapters.
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 mini little connectors (mini-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.
| Hardware State | Yellow LED (8 Gbps) | Green LED (4 Gbps) | Amber LED (2 Gbps) | Comments |
|---|---|---|---|---|
| Power Off | Off | Off | Off | |
| Power On (before firmware initialization) | On | On | On | |
| Power On (after firmware initialization) | Flash | Flash | Flash | All flash at the same time. |
| Firmware Fault | Flash in sequence | Flash in sequence | Flash in sequence | Flashing in sequence of yellow LED, green LED, amber LED, then back to yellow LED. |
| 2 Gbps Link UP/ACT | Off | Off | On/Flash | On for link up and flash if I/O activity. |
| 4 Gbps Link UP/ACT | Off | On/Flash | Off | |
| 8 Gbps Link UP/ACT | On/Flash | Off | Off | |
| Beacon | Flash | Off | Flash | All flashing at the same time. |

Cables
- 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
| 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) |
Because of their different core sizes, connect OM1 cables only to other OM1 cables. For best results, ensure that OM2 cables are not connected to OM3 cables. However, if an OM2 cable is connected to an OM3 cable, the characteristics of the OM2 cable gets applied to the entire length of the cables.
