v Follow the suggested actions in the order in which they are listed in the Action column until the problemis solved.v See Chapter 3, “Parts listing, Type 7979 and 1914 server,” on page 79 to determine which components arecustomer replaceable units (CRU) and which components are field replaceable units (FRU).v If an action step is preceded by “(Trained service technician only),” that step must be performed only by atrained service technician.Error code Description Action178x Fixed disk error.Note: x is the drive that has the error 1. Run the hard disk drive diagnostics tests on drivex.2. Reseat the following components:a. Hard disk driveb. Cable from the system board to the backplane3. Replace the following components one at a time,in the order shown, restarting the server eachtime:a. Hard disk driveb. Cable from the system board to the backplanec. Hard disk drive backplaned. (Trained service technician only) Systemboard1800 Unavailable PCI hardware interrupt. 1. Run the Configuration/Setup Utility program andadjust the adapter settings.2. Remove each adapter one at a time, restartingthe server each time, until the problem is isolated.1801 An adapter has requested memoryresources that are not availableNote: The server can allocate only 128 KBof option load space (option ROM space);error code 1801 occurs if the load spacerequired by an option ROM when loadingexceeds the available (remaining) loadspace. Changing the option load order cancause an option ROM that requires moreload space to load sooner, when more loadspace is available; the other option ROMsmight still fit in the remaining load space.With some options, some or all of the loadspace used is released after the ROM codeloads and initializes the option.1. If possible, rearrange the order of the adapters inthe PCI slots, to change the load order of theoption ROM code.2. Run the Configuration/Setup Utility program,select Startup Options, and change the bootsequence, to change the load order of the optionROM code.3. Run the Configuration/Setup Utility program anddisable some other resources, if their functionsare not being used, to make more spaceavailable.v Select Startup Options then Planar Ethernet(PXE/DHCP) to disable the onboard Ethernetcontroller option ROM.v Select Advanced Functions, then PCI BusControl, then PCI ROM Control Execution todisable the option ROM of adapters in the PCIslots.v Select Devices and I/O Ports to disable any ofthe onboard devices.4. If the problem remains, replace the followingcomponents one at a time, in the order shown,restarting the server each time:a. Each adapterb. (Trained service technician only) SystemboardChapter 2.
