Ethernet Applications Ungermann Bass Hub
4-4 Management Module Guide
Normal Operation
Displays information concerning the operational health of the hub and its
components. Possible states are other, Normal Operation, Hub Failure, Group
Failure, Port Failure, Control bus Error, or Temperature Problem.
Health data
Displays numeric information concerning the operational health of the hub
and its components.
Setting this object’s value to Yes causes a hub to be reset without affecting the
management state of the hub. The default choice is No if you do not want to
reset the hub.
Last Reset at
Records the value of sysUpTime anytime the hub is reset without
management data being reset. The resolution of the time stamp is only
required to be 100 milliseconds, which is 10 TimeTicks.
Setting this value to Yes requests that the hub perform a non-disruptive self-
test.
The hub performs a disruptive self-test, which does not affect management
data and does not inject packets onto any segment. Packets received during
this test may or may not be relayed. This test at least invokes the
functionality of the Execute SelfTest2 for each group in this hub cluster.
Click this button to access the Group Configuration View, which displays
additional product information. The fields for this view are described below:
Product ID
A string of ASCII characters representing the resident supervisor’s product
identifier for the cluster of concentrators attached to the Ethernet bus. This
cluster forms a single repeater.
Number of Ports
The number of ports in this group, including the AUI port, but not the
Ethernet backplane bus port.
Electronic Serial No
The Organization Unique Identifier as defined in IEEE 802.1A, Overview and
Architecture. This is the first 24 bits of UB’s MAC address identifying UB
uniquely worldwide and is a constant equal to 00DD00 in hexadecimal.
