Resetting the StackMaster
Reset the StackMaster™ in any of the following ways:.
•
Disconnect power cord to SNMP Management hub or to
StackMaster™ hub with installed SNMP management board, then
reconnect the power cord.
•
Press the reset button on the SNMP Management hub or
StackMaster™ hub with installed SNMP management board.
•
At the attached terminal or terminal emulation that has a
StackMaster™ configuration menu displayed, type and enter:
ANY MENU >
restart
ANY MENU >

At power on or reset, the Status LEDs cycle through diagnostic test
patterns as internal StackMaster™ software tests: Flash, serial port,
dynamic RAM, static RAM, dual port memory, and each of the Ethernet
ports.
After the diagnostic test patterns, for twenty seconds, the Status LEDs
display a pattern in which four LEDs remain illuminated while four LEDs
flash continuously. This pattern indicates that the StackMaster™ software
is waiting for an optional user interrupt.
Transferring the File
To transfer the file:
1.
Determine the exact drive and path to the updated .BIN file.
NOTE: Step 2 must be completed during the twenty-second period that
the Status LEDs display the optional user interrupt pattern.
2.
At the attached ASCII terminal or terminal emulation, type
and enter:
^X
(“control X”)
A file transfer message appears on the ASCII terminal or terminal
emulation.
