Battery Replacement
Single-rack ESP processors contain a replaceable lithium battery for maintaining the real time clock (RTC) capability of the system.
These batteries last at least 10 years from time of production and usually do not require replacement.

Power is on, but no sound
Sound is distorted
POWER LED is Red

• Plug in IEC power cord, check mains power.
• Verify that there is an input signal from the source using ControlSpace Designer
software. The audio input metering should be in the green/yellow band.
• Verify that there is an output signal. The audio output signal metering should be in
the green/yellow band.
• Using ControlSpace Designer software, verify that the audio input signal indicator
blocks are not showing solid red or flashing red. If they are, reduce the input
pre-gain setting to where the input is no longer clipping (red).
• Using ControlSpace Designer software, verify that the audio output signal indicator
blocks are not solid red or flashing red. If they are, and the input indicators are
green, use the Designer software to reduce the output gain or any intermediary
gain in the signal path.
• If the input source signal is clean when it enters the ESP system, and the input and
output indicators are green, verify that the loudspeakers are not being overdriven
and are not damaged.
• DSP configuration not loaded. Use ControlSpace Designer software to load a
configuration.
• Power-cycle the unit using the power cord. If the issue continues, call your Bose
Sales/Support representative.
• Verify that the ESP LAN port is connected to a PC.
• Verify that the Ethernet LAN connection on the PC is enabled. If it is not enabled,
the Link LED on the PC will probably be off.
• If connected to a hub or switch, check that device's Link LED.
• If using a rear-panel network card, unplug the ESP and try reseating the card.
• Ensure that the ESP processor is fully booted. The POWER LED should be a solid
green color.
• Verify that the LAN settings on the TCP/IP Ethernet device you are using on the PC
are set correctly:
- If not using a DHCP server, the IP address of the PC should be set manually to
an unused IP address (e.g. 192.168.0.2).
- The default IP Subnet mask is set to 255.255.255.0.
- Check firewall settings on the PC, unblock all ports.
• Verify that the proper NIC card is selected in ControlSpace Designer software
network tool.
• If using a rear-panel network card, make sure the front-panel network connection
is not plugged into the same network.
• Verify that there is not another ESP connected with the same address. If unsure,
disconnect one, scan for the remaining unit, and change its address. Repeat with
the second unit.
