Introduction This guide contains instructions on installing expansion cards, extra memory and processor upgrades in your computer. This document should be your only source of information when installing any of these. You should read this document before purchasing extra memory or a processor upgrade. If, having read the relevant instructions, you are not confident about installing the upgrade, you may wish to have your supplier or service organization install it for you.
Antistatic precautions All electronic components and equipments are sensitive to static electricity. Even small electrostatic discharges can render components useless or severely shorten their working life, therefore you should always take preventive measures. No work should be carried out on any item unless it is in a Special Handling Area (SHA) as defined in BS CECC 00015:Part 1.
Power down procedure If LOC Technology is in use, a user of appropriate authority must be logged on before the system can be powered down. 1. Push the POWER button and hold it until the system powers down. 2. Isolate the UPS batteries by setting the Battery Power switch to the ‘0’ position. 3. Unplug the mains power supply. Power up procedure 1. Ensure that the Battery Power switch is in the ‘0’ position. 2. Plug in the mains power supply. 4. Set the Battery Power switch to the ‘1’ position. 5.

Removing the drive cradle In order to install SIMMs it is necessary to remove the drive cradle. With the side panel removed as described in Removing the side panel the drive cradle can be removed as described below: 1. Undo the eight thumbscrews that secure the drive cradle. SIGNAL CABLE POWER CABLE HANDHOLD DRIVE CRADLE SECURING THUMBSCREWS DRIVE CRADLE SECURING THUMBSCREWS HANDHOLD PIVOT PINS 2.
3. Using the handholds provided at the front and rear of the drive cradle, lift the rear of cradle, swivelling it about the two pegs at the front. Warning When removing the drive cradle ensure that you support the front of the cradle, keeping the swivel cutouts against the locating pegs. Failure to do so may result in damage to SIMMs and the motherboard. 4. With the cradle at approximately 30° move it backwards to free it from the pegs and lift it clear. 5.
Adapter cards Eight 32-bit Micro Channel slots are available on the motherboard for adapter cards. Each slot has a blanking plate in the rear panel, and a notch in the adapter support metalwork at the front of the system unit. EXPANSION SLOTS BLANKING PLATE ADAPTER SUPPORT METALWORK SECURING SCREW FAN FRONT The two slots nearest the drive cradle (labelled 6 and 1) are both video slots. Slot 6 is fitted with the auxiliary video extensions.
It is recommended that slots 6 and 1 are left unoccupied (except for video cards), and slot 3 is left unoccupied (except for a secondary drive controller). Any other adapter cards should be fitted in slots 4, 5, 7 and 8 working down the system unit. Only after all these slots are full should cards other than video adapters or drive controllers be fitted in slots 6, 1 or 3. To install an adapter card: 1. Remove the side panel as described in Removing the side panel. 2.
Upgrading memory The FT//e Pentium motherboard has eight SIMM sockets which support a maximum of 256 Mbytes of RAM. These eight sockets are arranged in two banks of four. If SIMMs are installed in a bank all four SIMMs must be identical. The eight SIMM sockets are located beneath the drive bay as shown in the following illustration. MM8 MM7 MM6 MM5 SIMMS MM4 MM3 MM2 MM1 FRONT Each of the sockets is identified on the motherboard, from MM1 to MM8.
Apricot supplies and supports upgrades of 16, 32, 64 and 128 Mbyte capacities. The following table lists the possible capacities: Bank capacity (Mbytes) Bank 0 Bank 1 16 16 32 32 32 64 64 64 64 128 128 128 128 128 16 16 32 16 32 64 16 32 64 128 Total capacity (Mbytes) 16 32 32 48 64 64 80 96 128 128 144 160 192 256 Note For all cases the SIMMs in bank 0 could be swapped with those in bank 1 with no adverse affect.
Installing SIMMs Obtaining access To obtain access to the SIMM sockets you must remove, the side panel as described in Removing the side panel, and the drive cradle as described in Removing the drive cradle. Removing SIMMs If you wish to install an upgrade in a bank which is already occupied you must first remove the existing SIMMs. For each SIMM in the bank: 1. Lever the metal clips on each side of the socket gently away from the SIMM using your forefingers. 2.
2. Position the SIMM above the socket with the SIMM tilted slightly towards the rear of the system unit. 3. Lower the SIMM into the socket, and ensure that the SIMM is properly located in the connector. 4. Pushing gently on the top corners rotate the SIMM towards the horizontal until it clips into place. Do not use excessive force. If the SIMM will not rotate easily remove it and start again. 5.
Processor upgrades The FT//e Pentium motherboard is fitted with a Zero Insertion Force (ZIF) processor socket, ready for higher performance Pentium variants as they become available. The FT//e Pentium motherboard is ready to accept any processor with a Pentium compatible pinout, and a maximum external clock speed of 60MHz.
Removing the processor Before installing the upgrade processor you must first remove the existing processor. The processor is at the front left of the motherboard beneath the fan assembly. Instructions on locating the socket and removing a processor are given below. 1. Remove the side panel as described in Removing the side panel. 2. Note the position of all adapter cards and adapter cabling. 3. Disconnect all adapter cables and remove the adapters. 4.
5. Lift the fan assembly out of the system. 6. Identify the processor. PROCESSOR FRONT The processor is installed in a ZIF socket. A lever attached to the socket clamps the processor securely in the socket when it is parallel to the motherboard.
7. Carefully rotate the lever from the secure position until it is perpendicular to the motherboard FREE LOCKED The first and last 15° of movement may require considerable effort. Apply just enough pressure to overcome the resistance offered by the lever. 8. Once the processor is free of its socket lift it out of the system unit and place it on the anti-static foam provided with the upgrade processor.
Installation You are ready to install your new upgrade processor. 1. The upgrade processor and socket are keyed to ensure that the processor can only be installed in one orientation. One corner of the socket has an extra hole inside the others, the processor has a corresponding extra pin. The processor has a small dot of paint on its top surface to indicate the corner with the extra pin. If the processor has a heatsink fitted the paint dot may not be visible.
2. Carefully position the upgrade processor above the socket with the positioning guide on the processor over the keyed corner of the socket and the securing lever in the perpendicular position. PROCESSOR IN CENTRE Warning If the processor is misaligned it will not go into the socket, and any attempt to force it will damage the processor, or the socket, or both. 3.
Supplier upgrades The add-ons described earlier may be installed by a confident and competent user. The installation of additional (or replacement) drives is more complex, and should only be carried out by competent service personnel. Installing additional drives The Apricot FT//e provides a drive cradle that contains two bays with space for a maximum of five drives. These are: * Two 1/2 height drives at the front of the system unit. * Up to three SCSI hard disk drives at the rear of the system unit.
Expansion options The following table lists the possible upgrade routes for each possible combination of drives in each bay: Drive Current bay configuration Possible expansion Rear One 1" high drive One 1/2 height drive or One or two 1" inch high drives Two 1" high drives One 1" inch high drive One 1/2 height drive One 1/2 height drive or One 1" inch high drive Front No drive One full height drive or One or two 1/2 height drives or One 1" high drive or One 1/2 height and one 1" high drive One 1/2
