3. Chassis Installation and Assembly Tools and Supplies Needed • Phillips (cross-head) screwdriver (#2 bit) • Antistatic wrist strap (recommended) Safety Warning! Before You Remove the Side Cover Before removing the system side covers to work inside the system, observe these safety guidelines. 1. Turn off all peripheral devices connected to the system. 2. Turn off the system by using the push-button on/off power switch on the front of the system.
Warning and Cautions! These warnings and cautions apply whenever you remove the side cover of the system to access components inside the system. Only a technically qualified person should integrate and configure the system. Warning! System power on/off: The on/off button (a convex button) on the front panel DOES NOT turn off the system AC power. To remove power from system, you must unplug the AC power cord from the wall outlet or the system.
Opening the Front Bezel Take off the front bezel from chassis body. A key lock secures the front bezel to protect your system against unauthorised access: 1. Insert the key into the security lock, and turn it clockwise until it points to the unlock icon as figure 10. 2. Press two release button on top of front bezel and the pull it toward you (Figure 11). 3. Take off the front bezel from chassis body.
Removing the Side Cover 1. Remove the front bezel. Refer to the previous section for detailed instructions. 2. Loosen the three thumb screws (1) of the side cover. Figure 12: Loosening the Thumb Screws 3. Slide the side cover towards you until it is stopped (2), then upwards before taking it off from the chassis body.
Installing Hard Disk Drives and Cages The VIG840 supports the following hard disk drive cages: Figure 14: Hotswap & Non Hotswap Hard Disk Drive Cages Hotswap Drive Carrier The hard drive carrier is used in the Hotswap cage shown in Figure 14. Figure 15: Hotswap Drive Carrier Table 15: Hard Drive Carrier Features No Description 1 Contact Spring to chassis 2 HDD Power ON LED 3 HDD activity LED 4 Release button 5 Contact spring to upper 6 Lever 7 Air dam – must be installed if a hard drive is not present.
Installing a Hard Drive Carrier to the Hotswap Cage 1. Remove the air duct first. 2. Install a hard drive into the carrier, and then secure it with the four screws you can find in the screw bags supplier with each carrier. 3. Insert the hard disk carrier into the Hotswap cage with lever still extended (See Figure 16). Figure 16: Inserting a Hard Drive Carrier 4. Push the lever back until it clicks into place (See Figure 17).
Installing Hard Drives to the Non Hotswap Cage 1. Find the special mounting screws supplied with the server (See Figure 18). Figure 18: Special Mounting Screws 2. Put the hard drives into the cage and align with the mounting holes (See Figure 19). 3. Secure the hard drives to the drive cage using the screws shown in Figure 18. Figure 19: Mounting Holes on the Drive Cage Removing the Hotswap or Non Hotswap Cage 1. Loosen the four thumbscrews, which secure the hard disk drive cage to the chassis body. 2.
3. Disconnect the SCSI, Serial ATA, or power cables. If necessary the SCSI terminator also needs to be removed. 4. Finally continue to pull out the cage until it is totally out of the drive bay. Figure 21: Completely Removing the Cage from the Chassis Installing the 120mm Fan The VIG840 is designed to support three 120mm cooling fans with screw-less fan holders. There are two fans located in the middle of the chassis and one fan is mounted on the rear panel.
2. Next press the 120mm fan towards the fan holder until it clicks into place. You will find that the four positioning pins will insert into the four mounting holes of the 120mm fan around the frame. 3. Finally check that all four hooks of the fan holder have exactly fastened to the fan (See Figure 23). Figure 23: Checking the Fan Holder Hooks Installing a 120mm Fan to the VIG840 Chassis 1. Install the 120mm fan to the fan holder (See Figure 24). Figure 24: 120mm Fan Holder 2.
Figure 25: Mounting the Fan to Chassis Installing the Floppy Drive The VIG840 has a 3½” bay to hold a floppy disk drive. To install a floppy drive follow the below instructions: 1. Loosen the two screws (1) located on the side panel of the floppy disk drive carrier. Figure 26: Loosening the Two Screws 2. Insert the hooks shown by arrows in Figure 27 into the mounting holes of the floppy drive.
Figure 27: Mounting Hooks 3. Push the floppy disk drive down into the carrier and then secure the drive in place with the two screws that were removed earlier. Figure 28: Securing the Floppy Drive to the Carrier 4. Insert the drive carrier with the floppy drive installed into the 3½” bay until you hear a click sound. Figure 29: Installing the Drive Carrier to the Chassis 5. The floppy drive has now been successfully installed.
Installing a 5¼” Device The VIG840 can hold up to three 5¼” devices. The below instructions uses a CD-ROM drive to illustrate how to install a 5¼” device to the VIG840 chassis. 1. Remove a pair of slide rails from the side panel of the drive cage frame. Figure 30: Slide Rails 2. Insert both guide pins (Circled in Figure 30) on the slide rail into the mounting holes of the CD-ROM drive and then secure them in place with screws side by side. Figure 31: Securing the Slide Rails to the 5¼” Device 3.
Figure 32: Installing the 5¼” Device to the Chassis 4. The floppy drive has now been successfully installed. Add-on Card Guide and Retainer Detaching the Add-on Card Retainer 1. For convenience of installation or cabling the user may want to remove the add-on card retainer. 2. Push the release button on the top of the add-on card holder and then pull it out. Figure 33: Release Button on top of the Add-on Card Holder 3. Move it upwards slightly and then detach it completely from the chassis body.
Releasing the Add-on Card Retainer 1. Press both release tabs, shown in Figure 34 using red arrows and rotate the retainer towards you. Figure 34: Releasing the Retainer 2. Finally the clamp will be held in the position shown in Figure 35. The user can now install full length PCI cards, which will be guided and secured by the holder. Once all cards have been installed close the retainer.
4. Rail Kit Assembly Guide Rail Kit Features This latch allows for the slide rails to move in both directions.
This Latch releases the outer rail so that the server can be pushed back into the rack cabinet (One direction).
Outer Rail Outer View (Rear location): This is the rear adjustable extension plate located on the outer rail. Figure 40: Rear Adjustable Extension Plate Outer Rail Inner View (Rear Location): The rear adjustable extension plate can be adjusted by loosening the screws located on the inner side of the outer rail.
Outer Rail Outer View (Front Location): This is the front adjustable extension plate. Use the following screws to adjust the length of the rail to fit rack cabinet. Figure 42: Front Adjustable Extension Plate Outer Rail Inner View (Front Location): On the inner side of the rail you have high quality ball bearings which will be used to join the outer rail to the inner rail which is attached to the server.
Rail Kit Installation Step 1: Attach inner rail to chassis.
Step 2: Preparing the outer rail (Front). Use the screws shown below to extend the outer rail so that it fits your rack cabinet.
Step 3: Preparing the outer rail (Rear). Loosen the screws below to free the rear plate so that the outer rail can be extended to fit the rack cabinet.
Step 4: Preparing the rack cabinet. Firstly insert moveable screw nuts into the square holes on the front and rear sides of the rack cabinet. Next screw the rails to the front of the rack cabinet from the inside as shown below.
Step 5: Secondly, attach the rear of the outer rail to the back of the rack cabinet from the outside as shown below.
Step 6: Finally, tighten the two screws on the outer rail of the extension plate so that the rail is secure in the rack cabinet.
Step 7: Upload the chassis to the rack cabinet by lining up the outer rails which are now installed in the rack cabinet to the inner rails installed on the sides of the server. Once the rails are lined up push the chassis into the rack cabinet until lock position is achieved.
Step 8: Once the rails lock they need to be released by the inner rail latch so that the server can be completely pushed into the rack cabinet. The arrow below illustrates what direction to move the latch to release the lock. Figure 51: Releasing the Inner Rail The Server is now mounted successfully into the rack cabinet.
