About This Guide

Contents

This guide provides information for installing the TF85 tabletop
cartridge tape subsystem.
The TF85 tabletop subsystem is supported on the following
series of systems:
VAX 6000
VAX 4000
MicroVAX/VAXserver 3xxx (Q–bus)
MicroVAX II

Intended
Audience

This guide is for Digital Services personnel or qualified selfmaintenance customers who are installing the TF85 tabletop
cartridge tape subsystem on systems with DSSI bus adapters
in place. That is, the bus adapters to be used for connecting
the TF85 to the system must be embedded within the CPU
module or on an installed adapter module, such as the KFMSA
or KFQSA.

How to Use
This Guide

First read the next section, Before You Start, to prepare for
the installation. Then follow the procedure in Steps to Follow,
using the illustrations and examples as a guide.

Before You Start

Performance
Consideration

The VMS backup performance rate of the TF85 subsystem can
depend on the system processor. For example:
Connecting directly to an embedded bus adapter on such
systems as the VAX 4000 or VAX 6000 provides optimum
performance.
Connecting to a MicroVAX/VAXserver 3xxx (Q–bus) system
can reduce the rate of performance, but does not limit the
high capacity of data storage that the TF85 has.

Required Load
Device

The TF85, when connected to a KFQSA adapter installed
in a MicroVAX II or MicroVAX/VAXserver 3xxx system, does
not support booting of VMS or MicroVAX Diagnostic Monitor
(MDM) software. An additional load device is needed to boot
this software.

Required Tool

Although you can hand-tighten the screws that hold the
connectors in place, you need to use a flat blade screwdriver
to secure the connectors.

Choose a Site

2. Place the TF85 on a flat, sturdy, level area such as a desk
or tabletop—not on the floor:
Avoid a site that is dusty or humid.
Allow enough space around the TF85 for ventilation and
for easy access to the front and rear.

Affix Decals

3. If applicable, choose the foreign language decals with the
language appropriate for your country and affix them over
the English labels on the TF85 front panel. One decal
adheres to the cartridge insert/release handle, the other
adheres to the indicator panel (see TF85 Front View).

Power Off the
System

4. Check that the system manager has performed the following
steps:
a. Back up all disk integrated storage elements (ISEs).
b. Shut down the operating system.
c.

Halt the system.

d. Remove power from the system.

Select a DSSI
Node ID

5. Select a DSSI node ID plug with an ID that is unique from
any other devices on the DSSI bus.
DSSI adapters typically have the highest node ID number(s)
on the bus (7 when one adapter is on the bus; 7 and 6
for two adapters; 7, 6, and 5 for three adapters, and so
on). Tape ISEs typically have a low DSSI node number
(in most cases 0). Disk ISEs are typically assigned the
remaining DSSI nodes, after adapters and tape ISEs have
been assigned.
When adding a second TF85x to a DSSI bus, remember
that no two devices on the DSSI bus can have the same ID
number.
NOTE
Save the spare DSSI node ID plugs for future
system reconfigurations.
6. Insert the DSSI node ID plug into the DSSI node ID socket
on the rear panel (TF85 Rear View
) by aligning the two
center prongs with the two center slots and pressing the
plug into place.

Connect to the
DSSI Bus

7. Plug the DSSI cable into the leftmost TF85 DSSI connector
(TF85 Rear View
) by fitting the cable connector over the
two pins on the DSSI connector. First tighten the screws by
hand, then secure the connection with a screwdriver.

8. If this is the last device on this bus, attach the DSSI
terminator to the rightmost TF85 DSSI connector (TF85
Rear View
). Make sure the orientation of the terminator
is correct—it fits on the DSSI connector in one way only—
and push the terminator onto the connector. The spring
clips should lock the terminator in place.

NOTE
To remove the DSSI terminator for daisychaining, that is, connecting additional DSSI
devices to the TF85, squeeze the spring clips at
the bottom and top of the terminator as you pull
it straight out of the connector.
Remember to reinstall the terminator on the last
device of the DSSI bus.

WARNING
Remove the DSSI terminator only after shutting
off power to the entire system, including the
DSSI bus.
9. Connect the other end of the DSSI cable to the DSSI
I/O bulkhead on the system. Follow the procedures in
the system or DSSI adapter documentation (see Related
Documents in this guide).

Power

10. Be sure the TF85 power switch (TF85 Rear View

) is set

11. Connect the power cord to the TF85 power connector
(TF85 Rear View
). Make sure the connector is fully
seated.

12. Connect the other end of the power cord to a nearby ac
outlet.

Power On the
TF85

13. Set the TF85 power switch on. The power-on self-test
(POST) runs automatically when you power on the TF85.
Observe the indicators on the front panel:
a. The indicators on the front panel turn on sequentially,
from top to bottom.
b. All four indicators turn on simultaneously for
approximately three seconds.
c.

The green Operate Handle indicator and the two orange
indicators turn off.

d. The yellow Tape in Use indicator blinks.
e. With no cartridge loaded, the green Operate Handle
indicator turns on and the beeper sounds.
POST ran successfully if you observed the above. Proceed to
step 14 in Power On the System. Otherwise, see the following
section, POST Failure.

Steps to Follow, Continued

POST Failure

If all four indicators on the TF85 front panel blink, POST did
not run successfully:
Check the cable connections to make sure that they are
secure.
Press the Unload button on the TF85 front panel to reset
the TF85 and restart POST.
If all four indicators blink again, you most likely have a
hardware failure. See the Tx800 Series Magazine Tape
Subsystem Service Manual (EK–TF857–SM).

Power On the
System

14. After successful completion of POST, have the system
manager perform the following steps:
a. Restore power to the system.
b. Configure the system to recognize the TF85.
c.

Restart the operating system.

Configuration
Example

Configuration depends on the type of adapter or system you
have. Follow the procedures in the system or DSSI adapter
documentation (see Related Documents).
The following dialog is an example of configuring a VAX 4000
system in console I/O mode. The example uses the DUP utility
from system software and the PARAMS utility resident on the
TF85:
>>> SHOW DSSI
DSSI Bus 0 Node 0 (T8DBBB)

DSSI Bus 0 Node 1 (FRED)

The above command example uses BUS:0 0. For your
application, use the format BUS:n m where n = the bus number
and m = the node number on which you have installed the TF85.

Test the
Installation

15. Once the system is configured to recognize the TF85, load
a previously recorded data cartridge into the TF85 and test
the installation by running DRVEXR, a local program on
the TF85. (See the Tx85 Series Cartridge Tape Subsystem
Owner’s Manual for cartridge loading instructions.)

DRVEXR
Example

CAUTION
During the write/read operation, DRVEXR destroys
the data on the cartridge. Be sure to use a scratch
data cartridge.
DRVEXR is an intensive data transfer test that indicates the
overall integrity of the TF85. The following example shows
running DRVEXR from console I/O mode:
