The station’s display
To troubleshoot your charging station, pay attention to the messages that are displayed on the two-line
display. The display sequentially shows the name of the charging station and the current state of each of
its ports. The following example shows how a CT2023 displays the state of its #1 charging port under
normal conditions:
To determine the current strength of the communications signals, observe the small indicators on the
rightmost side of the display:
The top line displays the current state of the station’s charging ports. This line includes a port number
prefix and the station displays the state of each port sequentially.
The bottom line displays more information about the current status and, if applicable, instructions that
describe what action to take. Information is scrolled across this line.

LAN (802.15.4)
To top set of dots indicate the strength of the LAN connection. LAN is the local
connection that stations use to communicate to each other. All ChargePoint charging
stations have a LAN connection.
WAN (CELLULAR)
If the station is a Gateway, a bottom set of dots will indicate the strength of the WAN
connection. Gateways use this connection to communicate to the NOC (Network
Operations Center). If the station is a non-gateway, this signal indicator is not
displayed.

No signal*
*If a LAN signal is not available, the station may not be situated within 150’ line of sight of a gateway
station, or there may an obstruction. If a WAN signal is not available, it may be necessary to install cellular
repeaters at the installation site to boost the signal.
