Fibre Channel Gateway LEDs

The FC gateway provides one yellow (amber) LED and one green LED. Table 5-9lists and describes the LED indications.

Table 5-9:Gateway LED Indications

Display

Indication

yellow on, green off

Auxiliary power has reached the gateway.

 

 

green on, yellow off

Gateway runs successfully.

 

 

green on and yellow on

An error has occurred

 

 

FC Port LEDs

Fibre Channel Port LEDs are adjacent to each FC port. They indicate port status and activity. Each port has a one bi-color, green/yellow, LED to indicate port status. When you enable a Fibre Channel interface card, and a Fibre Channel device is already connected, the run light (LED) of the Fibre Channel interface port changes from yellow to green, indicating that a connection has been established between the Fibre Channel device and the port.

Figure 5-6displays the FC LEDs.

Led

Description

off

Optic module or cable is not attached.

 

 

solid yellow

A cable is attached but the port is offline.

 

 

slow pulsing yellow (2 second intervals)

Port is disabled, and fiber installed as the result of

 

diagnostics or Fibre Channel portDisable command.

 

 

fast pulsing yellow (half-second intervals)

Signal detected but port fault is also detected.

 

 

solid green

The port is online and a signal is detected.

 

 

slow pulsing green (2 second intervals)

The port is online with a loop-back cable attached or an

 

incompatible device.

 

 

fast pulsing green (half-second intervals)

The port is online but running some internal diagnostics.

 

 

sporadic flickering green

The port is online and packet traffic is detected.

SFS 3012 specifications

Cisco Systems SFS 3012 is a network switch designed to enhance the performance of data centers and enterprise networks. With its innovative architecture and advanced features, it caters to the increasing demands for high bandwidth and low-latency networking environments. This model leverages Cisco's expertise in networking technology to deliver reliable and scalable solutions for organizations.

One of the main features of the SFS 3012 is its ability to support high-speed data transfer with 10 Gigabit Ethernet (10GbE) ports. This provides significant improvement in data throughput, enabling faster communication between servers and network devices. With twelve 10GbE ports, the SFS 3012 is capable of handling intensive workloads, making it ideal for cloud computing and big data applications.

The SFS 3012 employs various networking technologies that enhance its operational efficiency. It supports data center bridging (DCB), which optimizes traffic flow and ensures low-latency communication for storage and server traffic. This feature is particularly beneficial in virtualization environments where multiple virtual machines operate simultaneously.

Additionally, the switch utilizes Cisco's innovative virtual extensible LAN (VXLAN) technology, enabling the creation of scalable, isolated virtual networks. This is crucial for enhancing network segmentation and security in multi-tenant data center environments. The ability to create virtual networks without the constraint of physical boundaries allows organizations to scale their networks seamlessly according to their needs.

Security is another critical characteristic of the SFS 3012. It implements advanced security protocols to protect the integrity of data transmissions. Features such as access control lists (ACLs), port security, and authentication protocols help safeguard sensitive information from unauthorized access.

Moreover, the SFS 3012 is designed with energy efficiency in mind. It incorporates features that minimize power consumption, helping organizations reduce their operational costs while also supporting sustainability initiatives.

In conclusion, the Cisco Systems SFS 3012 is a powerful network switch ideal for modern, demanding networking environments. With its high-speed connectivity, advanced networking features, strong security measures, and energy efficiency, it provides an effective solution for organizations looking to enhance their infrastructure and performance. As businesses increasingly embrace digital transformation, devices like the SFS 3012 will play a crucial role in supporting their growth and innovation.
