Introduction

1 IntroductionThis manual lists the installation accessories and provides a brief description ofthe connection of the DAT tape unit (briefly tape unit) to a cartridge-based DX200 exchange.




Principle

2 PrincipleThe DAT tape unit together with its accessories make up a Cartridge Tape Unit(CTU). The computers in the cartridge-based DX 200 exchange are connected tothe mass memory equipment via the SCSIF plug-in unit. The SCSIF has twooutgoing SCSI buses (0 and 1). Each bus can contain a winchester disk (WDU),CTU and magnetic tape unit (MTU) equipment, but only bus 0 can contain anfloppy disk unit (FDU). The various peripheral device types have their own SCSIaddresses (SCSI ID) on the SCSI buses. SCSI address 1 and 3 have been reservedfor the tape units in the DX 200 exchange.

The index of the DAT tape unit is determined as presented in Table 1.

Table 1. Index of DAT tape unit

DAT tape unit SCSI bus SCSI address

CTU-0 0 3

CTU-1 1 3

CTU-2 0 1

CTU-3 1 1




Accessories

3 AccessoriesThe following accessories are needed to install the DAT tape unit:

• DAT tape unit

• DAT tape (DDS-type)

• cleaning cassette

• plug-in unit DDAD or CTAD, one for each tape unit (attachment adapter)

• cartridge WDDC, one for two tape units

• plug-in unit SCSIT-S, two for each SCSI bus (terminal resistor)

• power supply PSC4, one for each tape unit

• SCSI bus cable

• power supply cable for WDDC cartridge, one for each power supply unit.




Installation

4 InstallationNo general instructions can be given regarding the switching off of the powersupplies of the exchange. The switching off must always be considered in a case-specific manner.

The DAT tape unit can be taken in use "hot", i.e. without shutting down the unit,if the exchange software contains the necessary program block and the equippingallows the installation of the tape unit, i.e. if the lower shelf of the WDDCcartridge contains a free slot connected to the SCSI bus and provided with powersupply. It must be taken into account, however, that the disconnection of the SCSIbus or the terminal resistors, even for a brief moment, will take the otherperipheral equipment connected to the bus out of operation and may direct theentire unit into test state. Therefore, the peripheral devices connected to the busmust be transferred to BL state before the installation can begin.

The installation takes place as follows: The strappings in the DAT tape unit areset as desired (see the chapter "Settings and strappings in DAT tape unit"). Theselection of supervision of the presence of the CTAD plug-in unit (W1) isstrapped to correspond to the selected SCSI address (3 or 1). The selection ofpower supply for the terminal resistor unit (W2) is strapped (1-2) so that thesupply does not pass via the diode. Finally, the signal and power supply cables areattached. The tape unit is fastened by screws to the CTAD plug-in unit.

If the lower shelf of the WDDC cartridge of the unit (slot 00 or 12) has no spacefor a DAT tape unit, another WDDC cartridge is needed to install the tape unitand power supply unit. The alarm controls of the power supply units are strappedat the rear of the WDDC cartridge (W2 and W4). The WDDC cartridgesconnected to the same SCSI bus are strapped as shown in Table 2.

Table 2. Strappings in WDDC cartridges

1 PS0 W2 1

1 PS1 W4 5



Next, the DAT tape unit is fastened in place as described above. If the SCSI buscabling must be extended, the SCSIT terminal resistor must absolutely be movedto the end of the cable.

5 Commissioning the DAT tape unit afterinstallation

When the unit has entered the WO-EX state after the power supply has beenconnected, the CTU automatically rises to BL-SY state ("no cassette tape").When a cassette tape is inserted in the tape unit (must be a DAT DDS tape), thetape unit enters state WO-ID. The state transition may take about a minute. Thetape unit can be monitored with the ISI or IMD commands.

If the unit does not change states according to the condition, the LED indicatorson the DAT tape unit should be observed. The LEDs should indicate that the tapeunit is in standby state. Also check the cabling and strappings.

Also make sure that the TAPEDR program block has been created, because theforced state transitions made with the ISC command are useless if the state of thetape unit does not change automatically according to the situation.

6.1 Settings and Strappings of HP Tapes

The HP DAT tape unit used in the cartridge-based DX 200 exchange is of typeHP 35480A, HP C1533A or HP C1554A (3.5", DAT, SCSI).

An asterisk (*) in Figure 1 indicates that the strapping or setting is made; in Tables3 and 4 it indicates that the setting is chosen. A question mark (?) indicates thatthe strapping or setting depends on the configuration.

Figure 1 shows the settings made under the HP DAT tape unit and the strappingsin strapping group W1 made at the rear. Table 3 describes the settings and Table4 describes the strappings.

Terminal resistors RN1 and RN2 are removed from model HP 35480A, becausethe bus contains SCSIT resistor cases. Models HP C1533A and C1554A containno terminal resistors.
