SAN Volume Controller 2145-SV1 Ethernet port LEDs

Edit online

Ethernet link and activity LEDs indicate the status of each Ethernet port.

  • An Ethernet-link LED indicates that the node is communicating on the network that is connected to the port.
  • An Ethernet-activity LED indicates an active connection on the port.

Ethernet ports on the system board

The operator-information panel LEDs refer to the Ethernet ports that are mounted on the system board (Figure 1).

  •  1  10 Gbps Ethernet port 1
  •  2  10 Gbps Ethernet port 2
  •  3  10 Gbps Ethernet port 3

The status of these ports is also indicated by LEDs next to each port (Figure 2).

  •  2  Ethernet activity LED

The Ethernet-link LED indicates that the node is communicating on the network that is connected to the port. The Ethernet-activity LED indicates an active connection on the port.

Ethernet ports on a 10 Gbps Ethernet adapter

If the SAN Volume Controller 2145-SV1 is equipped with a 10 Gbps Ethernet adapter, the port activity is not reflected on the activity LEDs of the operator-information panel. The activity of those ports is indicated by LEDs on the adapter itself, which are visible from the rear of the SAN Volume Controller 2145-SV1 (as shown in Figure 3). The adapter has two LEDs per port, arranged above the other. These pairs of LEDs are arranged in the same order as the ports.

  •  2  10 Gbps Ethernet link LEDs.

Ethernet ports on a 25 Gbps Ethernet adapter

The SAN Volume Controller 2145-SV1 node can support optional 2-port 25 Gbps Ethernet adapters. The system can support RoCE and iWARP networking adapters only for 25 Gbps iSCSI connectivity. LEDs indicate the activity on the ports on each adapter; however, the location and meaning of the LEDs differs, depending on the type of 25 Gbps card that is installed.

Figure 4 shows an example of the RoCE networking adapter. Each port on the 2-port 25 Gbps Ethernet adapter has one bi-color LED that indicates the status of the link.

Table 1 summarizes the possible values of the LEDs.

Color State Meaning
None Off The port is not active.
Green Solid The port has a valid link with no active traffic.
Green Flashing The port has a valid link with active traffic.
Yellow Flashing Indicates a problem with the link.

Figure 5 shows the 25 Gbps Ethernet host interface adapter (iWARP). Each port has a single LED that indicates the status of the port and link.
