SMART/sMART-E Interface OPTION, HEW 8t1 DRIVE

U~TACKING AND INSTALLATION CHECKLIST

This checklist is provided to aid you in unpacking and installing the PRIAM SMART/SMART-E Interface on a HEW 1070 8" Winchester disc drive. Please follow these instructions carefully and check off the operations in the order they appear on the sheet. It is important for protection of your warranty that these instructions be followed exactly.

UNPAC~ING AND HANDLING

Inspect the exterior of the shipping container for obvious signs of shipping damage. If there are indications that the container is damaged, NOTIFY THE CARRIER AT ONCE.

If no damage is apparent, open the shipping container and remove documentation, mounting hardware, and cables.

Check materials received in option package. They should include:

INSTALLING THE SMART/SMART-E INTERFACE

Insure drive is sequenced down.

Disconnect power to 8" drive.

NOTE: The following explanation will reference Figure 4.

Remove 6 mounting screws that hold the HEW MAIN PRINTED CIRCUIT BOARD ASSEMBLY (PCBA) to frame.

Connect one end of the 50 pin flat cable PIN 330420-03, to connector Jl on the HEW MAIN PCBA. Insure that Pin 1 of connector J1 on the PCBA connects to Pin 1 of flat cable.

Secure HEW MAIN PCBA to the frame using six 3/4" PCBA supports, PiN 101322. Refer to Figure 4.

Install PRIAM terminator, PIN 200133, into J2 on the HEW MAIN PCBA, if drive is last in string or only drive. Insure that Pin 1 of terminator is inserted into Pin 1 of J2.

Set the sector switches on the HEW MAIN PCBA at location

drive select switches on the HEW MAIN PCBA at location X59 for required physical address. Refer to Figure 1.

Switch X59 - 1 ON

Switch X59 - 2, 3, 4 OFF

This selects a drive address of one.

Set write Head ENABLE switches on the HEW MAIN PCBA at location N40 to ENABLE writing by setting:

Switch N40 1-4 ON. See Figure 1.

I I 10. Set switch on the HEW MAIN PCBA to DISABLE writing in the skip defect area by setting:

Switch

va-I

OFF

See Figure 1

I I 11. Fold and route loose end of 50 pin flat cable from J1 of the HEW MAIN PCBA to J1 of SMART or SMART-E PCBA and insure that Pin 1 of Jl

connects to Pin 1 of flat cable. Refer to Figure 4. Locate the (2) rubber bumpers approximately as shown on folded cable.

I I

12. Mount the SMART or SMART-E onto 3/4" PCBA supports. Press firmly until the supports come through mounting holes and lock. Orientation of the SMART or SMART-E PCBA should be as shown in Figure 4, with J1 of the SMART or SMART-E over J1 of the HEW MAIN PCBA.

I I

13. Insure that all SMART or SMART-E jumpers are in place according to the following listG

2A

PIN 300114 EC 1484 02/03/82

(3)

A. Jumpers for SMART Interface, refer to Figure 2 1. WI

This jumper should not be in place. If it is in the A position, PROM 12K is connected as a 2732 (this jumper ~s selected by a PCBA

trace) • 2. W2, W3, W4

These jumpers should be in place. When they are in, the PRIAM closed loop write clock or B level interface is selected.

3. W5

This jumper should be in place. This jumper enables the Head 4 line, used on the DISKOS 3450 and the DISKOS 7050.

B. Jumpers for SMART-E Interface, refer to Figure 3 I. Wl

If jumper WI is in the A to B position, the SMART-E Interface becomes compatible with the SMART Interface with respect to the operation of the DTREQ/, HRD/, and HWR/ lines. This configuration does not

support Direct Mode data transfers.

If jumper WI is in the B to C position, the SMART-E Interface will support Direct Mode data transfers. However, in this configuration, the SMART-E Interface is not compatible with the SMART Interface with respect to the DTREQ/, HRD/, and HWR/ lines. Position B to C is the recommended position.

NOTE:

2. W2

For a more detailed explanation refer to SMART/SMART-E specification.

This jumper should not be in place. Reserved for future use.

3. W3

This Jumper should be in place. This jumper enables the Head 4 line, used on the DISKOS 3450 and the DISKOS 7050.

4. W4, W5, W6

These jumpers should be in place. When they are in, the PRIAM closed loop write clock or B level interface is selected.

3A

5. W7

If jumper W7 is in the A to B position, parity is disabled on the host interface bus. If jumper W7 is in the B to C position, even

parity is enabled on the host interface bus.

6. W8

This jumper must be in the B to C position.

14. Remove current power cable and insert it into the corresponding

connector P2 of PIN 330421-02. Refer to Figure 4. Connect other end of power cable, PIN 330421-02, to J3 of HEW MAIN PCBAs

/ / 15. Route and secure the power cable, using tie wraps, as shown in Figure 4.

/ / 16. Connect the 2 pin power connector to J3 of SMART or SMART-E PCBA.

Refer to Figure 2 and 3. IMPORTANT. Insure that lip of connector is facing up and locks with J3 receptacle. INCORRECT ORIENTATION WILL RESULT IN DAMAGE TO PCBA.

/ / 17. Connect host (40 Pin) flat cable to J2 of SMART or SMART-E Interfaces / / 18. Connect main drive power to operate.
