AP2500 Hardwar e Refer ence Guide 11 I. Introduction I. Introduction T ools Required A few items are needed to install or remove the components in this server . • Phillips (cross) screwdriver • Standard (flat) screwdriver • Antistatic wrist strap Preparation 1.
12 AP2500 Hardwar e Refer ence Guide II. Components Server Front Side The front side of the server is provided to show the front exterior compo- nents of this server . The chassis is made of strong rust-resistant metal and covered with a protective ivory surfacing.
AP2500 Hardwar e Refer ence Guide 13 II. Components Server Back Side The back side of the server is provided to show the back exterior compo- nents of this server . II. System Components Chassis Security T o protect the server chassis from unauthorized intrusion, the chassis front panel can be locked with the built-in keylock.
14 AP2500 Hardwar e Refer ence Guide II. Components Chassis Panels There are two identical side panels on the chassis, one on each side. Each panel is secured by two lar ge thumb screws on the front of the server .
AP2500 Hardwar e Refer ence Guide 15 II. Components Chassis Circulation System The circulation system cools the hard disk drives by bringing fresh air in from the side of the server and forcing the hot air out through the back.
16 AP2500 Hardwar e Refer ence Guide II. Components Rear Cooling Fan Control Board Layout The rear fan control board, although small, has many functions as shown. Fan power connector Fan control settings Power input connector Fan status signal connector Rear Cooling Fan Control Board The rear fans are controlled and monitored by a control board.
AP2500 Hardwar e Refer ence Guide 17 II. Components Front Cooling Fans The hard disk drive fan module can be removed by using a small screw driver to push the eject lever in the fan module. The eject lever is behind a small hole as circled below . There are two individual 2 1/4 inch (6cm) fans secured by four screws on each fan.
18 AP2500 Hardwar e Refer ence Guide II. Components Front Cooling Fan Control Board The front cooling fans’ main purpose is to cool the hard disk drives. These fans also have a fan control board like the rear cooling fans. The front cool- ing fan module consists of a control board, a hard disk drive LED status board, and two cooling fans.
AP2500 Hardwar e Refer ence Guide 19 II. Components Fixed Storage Device T ray Internal fixed storage devices are mounted on removable trays. There are four available, one for a floppy device and another three for full-size de- vices. There are six screws provided (as circled) for mounting a 4 inch de- vice such as a floppy or hard disk drive.
20 AP2500 Hardwar e Refer ence Guide II. Components Fixed Storage Devices Floppy Drive and CD-ROM The floppy drive fits in the topmost bay along with the power button. A CD- ROM can fit into either the second, third, or fourth bay from the top. A metal clip on each side of the device tray secures the tray in place.
AP2500 Hardwar e Refer ence Guide 21 II. Components Hot-Swap T rays Maximum uptime in a server requires devices that can be easily replaced or “swapped.” The main hard drives are mounted in internal hot-swap trays for easy replacement. The AP2500 hot-swap bay has two different models.
22 AP2500 Hardwar e Refer ence Guide II. Components (This page was intentionally left blank).
AP2500 Hardwar e Refer ence Guide 23 II. Components II. System Components Hot-Swap Bay There are two levers on the front of the hot swap tray to help re- lease or lock the tray . T o remove the tray , extend both levers and pull on both levers. T o install the tray , push the tray firmly into the bay with the levers extended, then close the levers.
24 AP2500 Hardwar e Refer ence Guide II. Components II. System Components SCSI Backplane The SCSI backplane of this server is comprised of one SCSI board(DA- BP5) with Ultra2 SCSI connectors, power inputs, and SCSI ID dip switches. This configuration allows Ultra2 SCSI SCA hard disk drives to be docked into the server using a SCA connector .
AP2500 Hardwar e Refer ence Guide 25 II. Components II. System Components SCSI ID Setting SCSI ID settings are made through DIP switches located on the SCSI board. The SCSI board has four dip switches to set the hard drive’ s power on delay and SCSI ID.
26 AP2500 Hardwar e Refer ence Guide II. Components II. System Components SCSI ID Dip Switches The following illustrates the different possibilities using the dip switches. IDSEL 1=of f IDSEL 0=of f ON IDSEL 1=on IDSEL 0=on ON IDSEL 1=on IDSEL 1=of f ON ON IDSEL 1=of f IDSEL 0=on ON IDSEL1 IDSEL0 Slot1 Slot2 Slot3A Slot4 Slot5A off off Resv .
AP2500 Hardwar e Refer ence Guide 27 II. Components II. System Components SCSI Information SCSI Connections Y our server can support up to 15 user installed single-ended SCSI devices. Be sure to include both internal and external SCSI devices in your device setup.
28 AP2500 Hardwar e Refer ence Guide II. Components II. System Components Motherboard Securing Remove the extended expansion card guide before installing or removing the motherboard. All screws are necessary to provide the needed stabiliza- tion to support all the motherboard expansion cards used in a server .
AP2500 Hardwar e Refer ence Guide 29 II. Components II. System Components Cable Connections The cables connect to the motherboard as shown. The motherboard includes onboard SCSI with 68-pin and 50-pin SCSI connectors. RAID connections require the ASUS PCI-DA2100A RAID card.
30 AP2500 Hardwar e Refer ence Guide II. Components II. System Components Card-Secure Module The chassis provides an adjustable expansion card securing rack to help hold expansion cards in their slots. The securing rack module is mounted by four screws on the edge of the server .
AP2500 Hardwar e Refer ence Guide 31 II. Components II. System Components IDE Cabling Proper IDE device operation requires that the IDE ribbon cable does not exceed 18 inches. If only one IDE device is used, connect it to the end of the cable. Remove unused cables from the motherboard’ s IDE connector to ensure proper signal strength.
32 AP2500 Hardwar e Refer ence Guide II. Components II. System Components Ultra2 SCSI Disk Drive The Ultra2 SCSI disk drive has separate signal and power connections. The power connector is the same as standard hard disk drive power . The signal cable is different.
AP2500 Hardwar e Refer ence Guide 33 II. Components II. System Components Expansion Cards Expansion cards can be easily installed just like any standard PC computer . Up to 4 PCI or 2 ISA (1 slot is shared allowing a maximum of 5 cards at one time) cards can be installed.
34 AP2500 Hardwar e Refer ence Guide II. Components II. System Components Power Supply This server has a standard power supply with specifications to meet this server ’ s motherboard requirements. A clearly marked label gives detailed specifications of the power supply .
AP2500 Hardwar e Refer ence Guide 35 II. Components II. System Components Starting the Server T urn ON the server b y pushing the power button. The power button will snap back when released because A TX power systems have an electrical ON /OF F switch unlike A T systems which require a permanent ON or OF F position.
III. Appendix SCSI Cable Limits SCSI cables have a limit to the length that it may have. Exceeding the length may cause problems mounting or using any one of the SCSI devices. CAUTION: Exceeding the SCSI cable limits may cause unreliable data transfers even if all the devices are mounted properly .
