Dssi And Kzqsa Connectors - DEC 4000 Model 200 Operation Manual

The Break Enable/Disable switch also controls what happens
at power-up. When breaks are disabled (down, dot outside the
circle), the system attempts to automatically boot software at
power-up. When breaks are enabled (up, dot inside the circle),
the system enters console mode (indicated by the (>>>) prompt)
at power-up.
Using the console commands, SET HALT REBOOT and SET
HALT RESTART_REBOOT, you can set your system to override
the Break Enable/Disable switch and automatically boot software
after an error halt condition or power-up, even if breaks are
enabled.
Ethernet connectors—The CPU cover panel has two Ethernet
connectors: a BNC-type connector for ThinWire Ethernet and
a 15-pin connector for a standard Ethernet transceiver cable.
The Ethernet connector switch allows you to set the type of
connection. To use the standard transceiver cable connection,
set the switch to the up position. To use the ThinWire cable
connection, set the switch to the down position. A green indicator
light (LED) for each connector indicates which connection is
active.

1.1.1.4 DSSI and KZQSA Connectors

To the left of the card cage is a panel that provides two connectors: a DSSI
connector and a KZQSA In connector. The DSSI connector allows you to
expand your system with additional RF-series ISEs by connecting a system
expansion enclosure to the bus. You can also share ISEs with a second
system by forming a dual-host configuration.
The KZQSA In connector is for those systems using a built-in TLZ04 tape
drive. A 2.5-ft cable (BC06P–2F) links the TLZ04 tape drive and its KZQSA
controller through the KZQSA In connector. Figure 1–9 shows the location
of the DSSI and KZQSA In connectors.
