Using the EMM-E6 Hub View2-8Monitoring Hub Performance• Green indicates that the port is active; that is, the port has been enabled bymanagement, has a valid Link signal (if applicable), and is able tocommunicate with the station at the other end of the port’s cable segment.Note that an AUI or transceiver port will display as active as long as it has beenenabled by management, even if no cable is connected.• Blue indicates that the port has been disabled through management.• Yellow indicates that the port is enabled but does not currently have a validconnection. This usually indicates that the device at the other end of thesegment is turned off, or that there is no cable attached.• Red indicates that the port is enabled, but is not able to pass packets. Thisgenerally means that the port has been segmented by management afterexperiencing an excessive number of collisions; for a BNC (thin coax) port,however, this may only mean that no cable or terminator has been connected.• Magenta indicates that the EMM-E6 can’t manage the device.When the Admin Status port display option is active, only two colors apply: aport will be displayed in green if it is enabled by management, regardless ofwhether or not there is a cable attached or a valid link signal detected; a portdisabled by management will display as blue.When the FNB Channel option is active, an entirely different color scheme isemployed: salmon = Channel A; light blue = Channel B; orange = Channel C, andgrey = stand-alone.Monitoring Hub PerformanceThe information displayed in the Hub View can give you a quick summary ofdevice activity, status, and configuration.
