About Your System 33Solving Problems Described by LCD Status MessagesThe code and text on the LCD can often specify a very precise fault conditionthat is easily corrected. For example, if the code E1418 CPU_1_Presenceappears, you know that a microprocessor is not installed in socket 1.In contrast, you might be able to determine the problem if multiple relatederrors occur. For example, if you receive a series of messages indicatingmultiple voltage faults, you might determine that the problem is a failingpower supply.Removing LCD Status MessagesFor faults associated with sensors, such as temperature, voltage, fans, and soon, the LCD message is automatically removed when that sensor returns to anormal state. For example, if temperature for a component goes out of range,the LCD displays the fault; when the temperature returns to the acceptablerange, the message is removed from the LCD. For other faults, you must takeaction to remove the message from the display:• Clear the SEL — You can perform this task remotely, but you will lose theevent history for the system.• Power cycle — Turn off the system and disconnect it from the electricaloutlet; wait approximately ten seconds, reconnect the power cable, andrestart the system.I1916 Video Off in##(LCD lights witha blue or amberbackground.)The video will be turned offin xx seconds by the RACremote user.Information only.W1228 ROMB Batt <24hrWarns predictively that theRAID battery has less than24 hours of charge left.Replace RAID battery.
