P2ZCIM LED Status
The LED on each P2ZCIM indicates its operational state:
• If the LED blinks rapidly: P2ZCIM does not have a confirmed Communication Address.
• If the LED is primarily off and blinks on every two (2) seconds: P2ZCIM has a confirmed
Communication Address but is not switched to that Address.
• If the LED is on and blinks on/off rapidly when there is keyboard/mouse traffic: CIM has a
confirmed Communication Address and is switched to that Address.
Note: The P2ZCIM will blink from time to time even if there is no keyboard/mouse traffic;
this demonstrates that the P2ZCIM is operating normally and not locked.
• If the LED is blinking on and off but at a regulated, moderate speed (i.e., every half second):
that P2ZCIM is acting as Manager of the chain.
