Applications

PCIE Server NIC card Application

  • PCI-E NIC Cards provide redundant connectivity to ensure an uninterrupted network connection.

  • PCI-E NIC Cards are ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs.

  • They are specially designed for desktop PC clients, servers, and workstations with few PCI Express slots available.

PCIe2 FH 4-Port 8G Fibre Channel Adapter Overview

 

The IBM PCIe2 FH 4-Port 8G Fibre Channel Adapter is a high-performance adapter based on the Emulex LPe12004 PCIe Host Bus Adapter (HBA). This product is a generation-2 adapter and is supported on systems that support the generation-2 adapters. The adapter provides four Fibre Channel ports. Each Fibre Channel port provides single initiator capability over a fibre link. The ports have LC type connectors and use shortwave laser optics. The adapter connects to Fibre Channel switches and operates at link speeds of 2, 4, and 8Gbps. The adapter automatically negotiates with the switch to the highest speed of which the switch is capable. LEDs on each port provide information about the status and link speed of the port.

Cables are the responsibility of the customer. Use multimode fibre optic cables with short-wave lasers that adhere to the following specifications:

• OM3: Multimode 50/125 micron fibre, 2000 MHz x km bandwidth

• OM2: Multimode 50/125 micron fibre, 500 MHz x km bandwidth

• OM1: Multimode 62.5/125 micron fibre, 200 MHz x km bandwidth

 

Because core sizes are different, only OM1 cables can be connected to other OM1 cables. For best results, do not connect OM2 cables to OM3 cables. However, if an OM2 cable is connected to an OM3 cable, the characteristics of the OM2 cable applies to the entire length of the cables.

 

The following table shows the supported distances for the three different cable types at the three different link speeds.

 

Table 1. Supported cable distances by link speed

 

Cable type 2.125 Gbps 4.25 Gbps 8.5 Gbps
OM3 0.5 m - 500 m 0.5 m - 380 m 0.5 m - 150 m
OM2 0.5 m - 300 m 0.5 m -150 m 0.5 m - 50 m
OM1 0.5 m - 150 m 0.5 m - 70 m 0.5 m - 21 m
 

 

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 one 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.

 

Table 2. Normal LED states

 

Green LED Yellow LED State
Slow flashing Off Normal, link inactive or not started
On 2 fast flashes 2 Gbps link rate - normal, link active
On 3 fast flashes 4 Gbps link rate - normal, link active
On 4 fast flashes 8 Gbps link rate - normal, link active
 

 

Power-on self test (POST) conditions and results are summarized in Table 3. These states can be used to identify abnormal states or problems. Follow the action to be taken for each condition.

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

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