    Port Activity LED (green) The Activity LED indicates that data is passing through the port. Each frame that the port transmits or receives illuminates this LED for 50 milliseconds. This makes it possible to observe the transmission of a single frame. Transceivers The 8/20q Fibre Channel Switch supports SFP+ optical transceivers for the Fibre Channel ports.

  • Page 16: Ethernet Port

    Ethernet port The Ethernet port is an RJ-45 connector that provides a connection to a workstation through a 10/100 Base-T Ethernet cable (Figure 5). A workstation can be a Windows or a Linux server that is used to configure and manage the switch fabric. An Ethernet connection to the switch is required to manage the switch using the CLI, QuickTools, Simple SAN Connection Manager, or Simple Network Management Protocol (SNMP).

  • Page 17: Power Supply And Fans

    The serial port connector requires a null-modem F/F DB9 cable. The pins on the switch RS-232 connector (Figure 6) are identified in Table 3. For information about connecting the workstation through the serial port, see ”Connect the management station or workstation to the switch”...
