Figure 2-5. LED display of hub and NMM segment assignments
• Changes to the segment select switch override segment selection using
software.
• An NMM installed in a 100-series hub can be assigned using software to a
segment independent of the host hub, as shown in F
igure 2-5. By default,
an NMM is assigned to the host hub segment.
Check the segment LEDs on the hub to verify that the hub and its NMM
are correctly configured. For more information about NMM segment
assignments, refer to Using the BayStack 100-series Network
Management Modules.
• A BayStack Ethernet NMM provides the highest level of SNMP
management it is capable of (Standard, Advanced, or Advanced Analyzer)
to cascaded hubs on the same segment. NMMs of all levels provide
Standard management for all other segments in the stack.
Setting the Segment Select Switch
The default setting for the Segment Select switch is segment 1. To change the
segment assignment, use a ballpoint pen or similar sturdy pointed object to
move the switches to one of the positions shown in F
igure 2-6.
