PCIe2 8 Gb 2-Port Fibre Channel Adapter (FC EL5Y and EL5Z; CCIN 578D)

Learn about the specifications and operating system requirements for feature codes (FC) EL5Y and EL5Z adapters.

Overview

FC EL5Y and EL5Z are both the same adapter with different feature codes. FC EL5Y is a low-profile adapter and FC EL5Z is a full-height adapter.

The PCIe2 8 Gb 2-port Fibre Channel Adapter is a PCI Express (PCIe) generation 2 (Gen2), high-performance, based on the QLogic QLE2562 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 have LC type connectors and 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. See PCIe LP 8 Gb 2-Port Fibre Channel Adapter (FC EL2N; CCIN 577D) or PCIe 8 Gb 2-port Fibre Channel Adapter (FC EL58; CCIN 577D) for a 2-port 8 Gb Fibre Channel adapter based on an Emulex adapter.

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.
