Understanding Indicators 17
♦
Segment Utilization % (10Mbps and 100Mbps)
The utilization bar graphs provide a quick reference on the current traffic
load relative to the total available 10Mbps or 100Mbps network band-
width. The graphs display a measure of the percentage of bandwidth in
use on the respective network segment. All data packets are counted,
whether valid or not.
♦
Hub ID Indicator
The Hub ID readout shows the ID (group) number of the hub within the
hub stack. The first time a hub is powered on within a hub stack, the
master hub in the stack assigns that hub an available ID number which is
then added to each hub
factory serial number (encoded on an EEPROM
memory chip). The hub ID is then permanently assigned.
In an unmanaged stack (all slave models), all IDs will read “0” and no
permanent ID assignment is made. In a stack with a master (intelligent)
model, the master hub will detect the other hubs in the stack and auto-
matically assign ID numbers which are then permanently saved by each
hub.
Module Indicators
The two module indicators, SLOT1 and SLOT2, indicate a good link to a
module installed in the respective slot. For the DFE-260S switch module the
indicator will come on when the module is installed. For the DFE-260FX
and DFE-260TX modules, the slot link indicator should light whenever the
module is installed and there is a valid link.
