Figure 1-5. I/O Panel System Memory The PowerEdge 4200 systems have a minimum of 64 MB of 72-bit-wide, buff- ered EDO memory. The system memory capacity can be expanded to 512 MB by using combinations of 32- and 128-MB buffered, EDO DIMMs.
Plug and Play ISA expansion cards and PCI expansion cards the next time the system is rebooted. Chapter 5, “Using the EISA Config- uration Utility,” in the Dell PowerEdge 4200 Systems User’s Guide describes the EISA Configuration Utility and provides instructions for using it to configure the system.
Each device attached to the 7860 Ultra/Narrow SCSI host adapter must have a unique SCSI ID number from 0 to 7. When Narrow SCSI devices are shipped from Dell, the default SCSI ID num- bers are assigned as follows: •...
The following subsections provide service-related information about the system unit. System Power Supply The PowerEdge 4200 system contains either one 700-watt power supply (non- redundant configuration) or two 700-watt power supplies (redundant configuration). Each installed power supply can operate from an AC power source of 90 to 265 VAC at 50 or 60 Hz.
The power-supply output voltages for nonredundant systems can be measured at the connectors on the back of the power supply (P1, P2, P3, P4, and P5) or at 1-10 Dell PowerEdge 4200 Systems Service Manual Table 1-1. DC Voltage Ranges Voltage Range +3.135 to +3.465 VDC...

System Cooling The Dell PowerEdge 4200 system contains three redundant cooling fans in the left side of the chassis. Two of the fans are used to cool the system, and the remaining fan is activated only in the event of the failure of one of the two pri- mary fans or in the event of an over-temperature condition in the chassis.
Main Memory The eight DIMM sockets on the system board can accommodate combinations of 32- and 128-MB DIMMs up to a total memory capacity of 512 MB. The sys- tem is shipped with high-speed (60-ns) 3.3-V EDO DIMMs installed. When reinstalling DIMMs, use the following guidelines: •...

5. Observe the monitor screen for the Dell Server Assistant logo screen. nternal Visual Inspection A simple visual inspection of a computer’s interior hardware can often lead to the source of a problem, such as a loose expansion card, cable connector, or mounting screw.
Dell Server Assistant logo screen appears on the monitor, followed by a screen containing icons of the options available. If no errors are found in main memory and the Dell Server Assistant loads, select the Run System Utilities icon. Then select the Run System Diagnostics icon and press <Enter>.
If none of the troubleshooting procedures in this chapter or the tests in the system diagnostics reveals the source of the problem or leads to the proper trou- bleshooting steps for determining the source of the problem, call Dell for technical assistance. For instructions, see Chapter 11, “Getting Help,” in the Installation and Troubleshooting Guide.
Chapter 3 Beep Codes and Error Messages his chapter describes beep codes and system error messages that can occur during system start-up or, in the case of some failures, during normal system operation. The tables in this chapter list faults that can cause a beep code or sys- tem error message to occur and the probable causes of the fault in each case.
