System Utility MenuUPDATE F IRMWARE Write security: 1; Read security: 5Updates firmware when ATLAS 550 enhancements are released. Two trans-fer methods are available for use in updating any modules that containFlash memory—including the ATLAS 550 system controller.The first transfer method uses the ATLA S550 serial Control/Chain In portof the system controller and XMODEM protocol. For detailed informationon how to update firmware using this method, see XMODEM Firmware Up-dates on page 12-1.The second transfer method uses the ATLAS 550 built-in Ethernet port of thesystem controller and TFTP (Trivial File Transfer Protocol). For detailed in-formation on how to update firmware using this method, see TFTP FirmwareUpdates on page 12-3.
