LED | transmitted to the NMM when an SNMP link is |
| established. |
Segment Utilization LEDs | Lights to indicate the total percentage of segment |
(top row of 8 LEDs per | (not module) bandwidth being utilized at any time |
segment) | on the specified segment (1 or 2). Bar display |
| indicates hub utilization at 1, 3, 5, 10, 20, 30, 50, or |
