OmniSwitch 6855 Series Chassis and Hardware Components OmniSwitch 6855-U24 Refer to the illustration below for more front panel information. For detailed LED descriptions, refer to page 2-21. For information on the chassis rear panel, refer to page 2-23. USB Port Status LEDs For information on the OS6855-U24's status LEDs, refer to page 2-21. 1000Mbps SFP The OS6855-U24 provides 22 non-combo SFP connectors (1-22) and 2 combo SFP connectors (24-24) for supported SFP transceivers. Console Port The OS6855-U24 front panel provides one RJ-45 port for console connections. Console connections are used by network administrators for switch management. This female RJ-45 connector provides a DTE console connection. Combo RJ-45 10/100/1000 The OS6855-U24 provides two combo 10/100/ 1000BaseT. By default, when an SFP is installed in a combo port, it takes over the port number of the corresponding RJ-45 Ethernet port. In other words, if an SFP is installed in the slot labeled 24, Ethernet port 24 would no longer be available and cannot be used for 10/100/1000 traffic. This default setting is referred to as "preferred fiber." Refer to "Configuring Ethernet" in the Network Configuration Guide for detailed information, including steps for configuring combo port settings.
