2)

Check the Power LED to ensure that the switch is turned on.

 

3)

Verify that the SFP is firmly seated.

2)

Unplug the fiber cable from the node and verify that an optical signal is

 

present on the cable receiver lead.

 

3)

Verify that the fiber cable is fully seated at either end.

 

If optical power meter is available, verify the device is transmitting a signal.

 

If there is no signal present, the device may require rebooting, device drivers

 

may need to be reinstalled, or the HBA or disk controller hardware may require

 

servicing.

 

If a signal is present on both the cable lead and the end node, the HBA or disk

 

controller may require service.

 

4)

Ensure the device and switch are operational and set to the same speed.

1)

Verify that the proper HBA device drivers are loaded for the appropriate

 

operating system and that the host has been configured to recognize attached

 

disk devices.

 

2)

Improper FC-AL initialization could result from a defective or inoperative

 

adapter card or device. Run adapter diagnostics with a loopback connector to

 

see if the adapter is working properly.

 

3)

Unplug the fiber cable from the end node and verify that an optical signal is

 

present on the cable receiver lead. If no signal is present, the cable’s receiver

 

lead may be bad and the device may be streaming F8 Failure notifications.

355 specifications

The Emulex 355 is a high-performance network interface card (NIC) designed specifically for data centers requiring advanced connectivity, reliability, and speed. With the rapid evolution of data transmission technology, the Emulex 355 stands out due to its robust features and capabilities that cater to the demands of modern IT infrastructures.

One of the key features of the Emulex 355 is its support for 10 Gigabit Ethernet, which allows for significantly faster data transfer rates compared to standard Gigabit connections. This increased bandwidth is essential for handling large volumes of data traffic, particularly in virtualized environments and cloud computing applications. Its high throughput ensures that data can be transmitted rapidly across networks, minimizing latency and improving overall performance.

The Emulex 355 employs advanced technologies such as iSCSI Offload and FCoE (Fibre Channel over Ethernet), which help enhance data processing efficiency. These technologies allow the card to offload processing tasks from the host system's CPU, reducing the load on server resources and optimizing performance. The result is a more efficient system that can handle more concurrent connections and processes without being overwhelmed.

In addition to speed and efficiency, reliability is paramount in data center operations. The Emulex 355 includes features like error detection and correction, ensuring data integrity during transmission. Built-in redundancy and failover capabilities safeguard against potential network disruptions, allowing for continuous availability of services—a crucial aspect in mission-critical environments.

The Emulex 355 also offers support for various robust networking protocols, enabling seamless integration into existing network infrastructures. Its compatibility with multiple operating systems and virtualization platforms, such as VMware and Microsoft Hyper-V, further enhances its versatility.

Another notable characteristic of the Emulex 355 is its energy-efficient design. It is optimized for lower power consumption without sacrificing performance, aligning with contemporary efforts to reduce the carbon footprint in data centers.

In conclusion, the Emulex 355 NIC is a powerful solution equipped with features that address the complex demands of modern data centers. Its combination of speed, reliability, and efficiency, along with advanced technologies, makes it a preferred choice for organizations looking to enhance their network capabilities and ensure smooth, uninterrupted operations.
