◊ Manual Partition
The indicator of a port lights amber continually when the port is
Manually partitioning a port has the same effect as automatic
partitioning, except that you must also manually re-enable it. You can
choose to manually partition a port even if there is nothing wrong
with it, for example to prevent a certain device from accessing the
network or to reduce network traffic.
No incoming packet transmission can occur on a manually partitioned
port. Ports can be partitioned and re-enabled using an SNMP-based
network management system, or using the console menu interface.
♦ Master (manageable models only)
The Master indicator lights to indicate that the master hub is serving as an
♦ Console (manageable models only)
The master hub's Console or Out-Of-Band indicator will light to indicate
whether the hub's RS-232 console port is being used for the console
interface or for out-of-band network management using the SLIP
protocol. The mode of the console port may be set using the console
interface or using an SNMP-based network management system.
♦ FCS/Align (manageable models only)
The FCS (Frame Check Sequence)/Align indicator lights amber to
indicate that data packets have been corrupted during transmission. An
FCS error occurs when a data packet fails an internal consistency check.
An alignment error occurs when the bits in a packet don't add up to a
whole number of bytes.
