Checking, Testing and Resetting the PMB

unit via an Ethernet link. You may be required to carry out the following checks / actions:
• Check that PMB LED #0 is blinking green (PMB booted correctly):
When the system is powered on, the 7 activity and status LEDs (LED #1-LED #7) are
switched off and LED #0 is blinking. See PMB Leds and Code Wheels, on page 4-50.
• Check PMB code wheel settings. See PMB Leds and Code Wheels, on page 4-50.
• Check that the Ethernet cable linking the server to the PAP unit is correctly inserted and
that the Ethernet link LED is green.
• Check the PAP - PMB link by pinging the PAP and the PMB:
PAP Address
PMB 0 Address PMB 1 Address PMB 2 Address PMB 3 Address
