If this is a new installation, turn on the power to the DEChub 900
MultiSwitch. If the module was installed while the DEChub 900
MultiSwitch was powered up, seating the module will initiate the
module’s power-up sequence. Refer to Figure 2-9 to see the location of
the LED indicators.
Stage Description
1 Upon receiving power, verify that the module’s Power LED
lights immediately and that the Module OK LED lights
within five seconds. Also upon receiving power, the module
performs a self-test. The self-test should complete in 25
seconds for a module with 4MB of memory and 67 seconds for a
module with 16MB of memory.
2 After the module completes self-test, the Power LED , the
Module OK LED , and the Network OK LED remain lit.
The Network Activity LED blinks at a rate proportional to
the amount of activity on the port.
NOTE: If the LEDs do not operate as described, refer to the section
titled Problem Solving Using the LEDs.
