Troubleshooting
Turn on the input devices (DVD players, Blu‑ray players, PCs, and other sources), output
devices (display screens, projectors), the control processor, and the PC and touchpanel or
eBUS button panels. Touch a configured button on the touchpanel or eBUS button panel.
If an input or output AV device cannot be remotely controlled (does not respond as
expected), check the following:
•
•
Power Connections and Circuit Breaker
•
•
•
The unit (host) name is any name (for example, Room730‑IPLEXPPDU4H or ConfRmSyst)
that you want to use to label a specific EXP unit. The default is a combination of the
product name and part of the hardware (MAC) address. This can be changed to your
choice of alphanumeric characters and hyphens (‑). The following rules apply:
•
Spaces are not permitted within the name of a unit or at the start or the end of a
name.
•
Underscores ( _ ) are not permitted.
•
Valid characters are A‑Z, a‑z, 0‑9, and ‑ (hyphen).
•
The unit does not distinguish between upper and lower case letters.
•
The name cannot start with a number or a hyphen, and it cannot end with a
hyphen.
•
Maximum name length is 63 characters.
Power Connections and Circuit Breaker
Data Connections
Ensure that all devices are plugged in.
Make sure that each device is receiving power. The IPL EXP PDU4H front panel power
LED lights if the unit is receiving power.
For the AC power output ports, verify that the unit is not in the overload state and the
circuit breaker has not been tripped. View the red Breaker LED on the front panel. If
it is lit the breaker has been tripped. The unit reports the state as
Closed
. If a load is connected to the ports, and GC software or the IPL EXP embedded
web page show the current as zero, the breaker has been tripped. To restore these
ports to normal function, do the following:
1.
Correct the hardware cause of the overload. Disconnect all of the devices from the
IPL EXP power output ports.
2.
Press the circuit breaker button to reset the circuit breaker. The unit waits a moment
and rechecks the ports.
NOTE: AC output power remains off until the circuit breaker is reset, unless the
Manual Control contact closure port is closed (On).
3.
If the total (aggregate) current is within safe limits, connect the devices to the
IPL EXP and turn them on (either one‑by‑one or all of them at once).
•
If current levels are safe, the unit continues normal operation. The current
reading in Global Configurator or the embedded web page changes from
show the new amount of current being drawn from the outputs.
If the aggregate current is outside safe limits (it exceeds the maximum
•
threshold), the circuit breaker trips again, and the AC output ports remain off
until the breaker is reset (after the overload is corrected).
a.
Repeat step 1 (disconnect all devices from the power ports) and step 2
(reset the circuit breaker).
