Introduction to 0
The 428XL instrument introduced by S _ R] _ L Company mainly uses HPxw8600 workstation as the instrument server. HPxw8600 works.
The station is built on the platform of INT _ L 5400, which has strong processing capacity, high stability and availability, and high expansibility. The installation of R _ b [tent _ RPRCs _ lcnuxv4 operating system gives it a powerful number.
According to processing and computing power.
Due to the harsh working environment of field exploration, affected by temperature, humidity and the bump of the instrument car during the relocation, the workstation often has software and hardware failures. Therefore, it is necessary to quickly find out the cause of the failure and eliminate the failure, so as to reduce the downtime and economic losses caused by equipment failure.
1 Basic composition of workstation
HPxw8600 workstation adopts tower structure, and the workstation chip
This group adopts Intel server/workstation dual-purpose chipset Int_l5400. HPxw8600 workstation supports dual independent bus technology, and can support dual quad-core Xeon processors point to point. The workstation motherboard provides 8 memory slots, and the maximum memory can be upgraded to 32GB；; The workstation chassis provides four 3 "5" hard disk carriers, which can install four SATA/SAS hard disks. Generally, Lcnux system is installed with three hard disks.
2. Workstation self-check
After the HPxw8600 workstation is started, the POST program will be executed, which is a series of diagnostic tests that run automatically when the system is turned on. If POST encounters a problem, it will give a sound or text prompt (or both) before the operating system starts. It is a key step for all computer systems to check the state of each component of the system and display the process and results of self-inspection. After the self-check, the system will automatically load the installed operating system (Lcnux) and start booting. Users can judge the fault of system hardware by the messages, fault codes and sounds displayed on the screen.

4 workstation memory module and hard disk features
4 inches 1 memory module
The memory module configuration on the motherboard of HPxw8600 system supports 8 DIMM slots, using DDR 2-667 (double data rate-667MHz) and fully buffered DIMM(FBD). The maximum configuration of 4GBDIMM on the system motherboard is 32GB, and the maximum memory can reach 128GB after adding expansion cards. Can be configured as single channel (one DIMM), dual channel (two DIMMs) or four channel (four DIMMs); The storage module is shown in figure 1.
In order to ensure the correct installation, the memory module and its slot are designed with grooves. When installing the memory module, make sure to align the rail settings. If multiple memory modules are installed in the workstation, each channel is paired with a memory module supported by a motherboard of the same size and type. The memory module installation principles that must be followed are:
(1) If the memory module is installed, install it in the slot 1;
(2) If two memory modules are installed, put them in the slot.

5 Matters needing attention in hardware maintenance
Right: 1/5
Figure 1 Schematic diagram of storage module
The memory, hard disk, CD-ROM drive, fan and other components in the computer system are vulnerable devices. In addition, workstations are used in field production, and the working environment is harsh, so these components are more prone to failure. In daily maintenance and troubleshooting, we must follow the standard safety procedures and steps, especially to eliminate the influence of static electricity, and pay attention to the following points:
(1) When the installer works as a workstation, please make sure that the cooling hole of the workstation is open.
The influence of wind;
(2) The workstation should be as far away from the equipment that produces magnetic field interference as possible; (3) If four memory modules are installed, install them in the slot pairs: 1/3 and 5/7; (4) If 6 memory modules are installed, install them in slot pairs: 1/3, 5/7 and 2/4; (5) If eight memory modules are installed, please install them in the slot pairs: 1/3, 5/7, 2/4 and 6/8. 4 "2 hard disk system -SAS hard disk
The hard disk of HPxw8600 workstation is SAS(S _ RC[LATT[-]B _ SCSI] hard disk, that is, serial SCSI. The new generation of SCSI technology, like the popular S _ RC [LATA (SATA) hard disk, adopts serial technology to obtain higher transmission speed and improve internal space by shortening the connecting cable. SAS is a brand-new interface developed after parallel SCSI interface. The purpose of this interface is to improve the performance, availability and scalability of the storage system, and to provide compatibility with SA- TA hard disk.
Figure 2 Schematic diagram of hard disk interface
SAS controller can be used for SAS hard disk and sa-
TA hard disk and SATA cable can be plugged into SATA and SAS ports. On the other hand, SAS hard disk cannot be plugged into SATA interface.
In order to prevent users from connecting to SAS hard disk.
When it is connected to an interface that can only support SATA hard disks, there needs to be a plastic bump on the SAS cable to prevent users from plugging it in incorrectly. Hard disk connection on HPxw8600 motherboard
(3) Keep the equipment ventilated and dry, and power on the workstation regularly to prevent the electronic equipment in the workstation from being damaged by moisture;
(4) Try to avoid hot-plug keyboard and mouse, that is, the current workstation supports plug and play of external devices, and hot-plug will also reduce the service life of the interface;
(5) Take anti-static measures. Static electricity may damage the workstation chip. To avoid this, the main chassis must be grounded. Before opening the cabinet and after shutting down the system, the power cord of the workstation must be disconnected (internal components may turn on the power). Only after the operator touches the dischargeable object by hand can the cabinet be opened for maintenance.
(6) Prevent dust hazards. The accumulated dust will make the hardware generate static electricity during operation. In severe cases, excessive dust will generate static electricity and damage the hardware. Therefore, the chassis should be dusted regularly to ensure the working environment in the workstation chassis is clean.
6 concluding remarks
In short, in the face of increasingly powerful computer systems.
It is extremely necessary to master the necessary hardware technology and daily careful maintenance.
Only in this way can we ensure the normal operation of the instrument and better serve the field production.
Take the exam and contribute.
