2. Hardware ComponentsThe following sections describe the E Snake system hardware. This includes the ESF and ES2master units as well as each of the optional I/O cards that are used to populate the frame cardcage.2.1 The E Snake Frame (ESF) and ES2 Master UnitsFigure 1. E Snake Frame FrontFigure 2. ES2Each E Snake master unit consists of a hardware frame and motherboard that can be configuredwith input cards and output cards. Each card is capable of processing eight channels of audio.2.1.1 Front Panel Indicators and SwitchESF requires the use of an external power supply; ES2 contains an integrated internal supply.Both units provide connections for attaching a second external supply if redundancy is desired.Groups of green LEDs indicate presence of DC voltages (ESF only). The LED monitoring eachDC voltage will fail to illuminate if the corresponding supply is not delivering that voltage.
Large Blue Light indicates unit is powered on.Blue Control LED blinks to indicate communication activity between the ES unit and ESC.Red Fault LED indicates that an error has occurred in the system. When this LED isilluminated, there will be a corresponding error code displayed in the LCD window. Refer toAppendix B for a list of error codes for help troubleshooting in the unlikely event of systemproblems.The LCD window provides a view of the setup and operating information of the ES unit. (Theavailable messages are listed in Appendix A.) The main idle screen shows the name assigned tothe ES unit, IN USE indicates a good CobraNet connection and COND identifies whichCobraNet device is acting as the system conductor. Other units will display PERF to indicate thatthey are not the CONDUCTOR, but merely PERFORMERS in the system. Refer to the sectionon CobraNet Basics.The Black Pushbutton pages through the LCD message screens and allows the user to see thecurrent system operating parameters and also is used to reset the ES unit.RESET reconfigures the unit’s persistence memory. When the ES unit is powered off, theoperational state of the software is maintained in nonvolatile memory. If input or output boardchanges are made, resetting the unit will acknowledge the new board configuration and reset allTransmitters (Tx) and Receivers (Rx) to 0. Hold the button in for 10 seconds and the ResetConfirmation Screen will appear. Push the button again to perform the reset.A single push of the button will clear non-critical error messages from the LCD and Fault LED,although the message will reappear if the error condition persists.2.1.2 ESP1 Power SupplyThe ESP1 provides the various voltages required by an ESF. A second supply may be employedif redundant power is desired. Connections are made via the cable and NL8 Speakon ® connector.The ESP1 Supply provides power for a single ESF. Each ESF features connection jacks andmonitoring LEDs for two ESP1 power supplies, A and B. Connection can be made from an ESP1to either of the ESF’s NL8 power supply input jacks for single supply operation.
