VAXstation 3100 (Model 48) System 53
The position of the Ethernet switch determines which of the Ethernet
ports provides IEEE 802.3 network communications. An LED is lit next
to the enabled port. The keyboard is connected to the keyboard port either
on the back of the system box or on the monitor end of the video cable.
The mouse or tablet is connected to the mouse port either on the back
of the system box or on the monitor end of the video cable. The external
SCSI port is for connecting external mass storage devices to the system.
The monitor or an external mass storage device can be plugged in the
switched ac outlet.
The S3 switch next to the LEDs on the back of the system module controls
the console port. When the S3 switch is in the down position, it enables
the monitor connected to the monitor port to be the console. When the S3
switch is in the up position, it enables a terminal connected to the printer
port to be the console.
5.2 FRU Removal and Replacement
The only new FRU in the model 48 system is a new system module.
However, since this system module and all of the other FRUs are removed
and installed the same way as the FRUs in the VAXstation 3100 model
48, all removal and replacement procedures for the VAXstation 3100
model 48 are covered in Chapter 5 of the VAXstation 3100 Maintenance
Guide (VAXstation 3100 (Model 48) System).
