2.9.2 Resetting the OECmux II Unit to Factory Settings
A similar feature exists on the DECmux II unit to reset the supervisor pass-
word, composite link parameters and asynchronous port parameters to factory
default values. The DECmux II unit has a RESET SWITCH which is inside
the unit. To reset to factory settings proceed as follows.
NOTE
DIGITAL recommends that reset to factory settings on a DECmux
II unit only be performed by a qualified service technician.

WARNING
I
This procedure requires power to be applied with the protective
cover removed. Damage to the hardware/user could result if not
done correctly.
1.
Turn off the power and remove the power cord.
2.
Remove the top cover from the DECmux II unit.
3.
Locate the red push button switch beside the fan.
4.
Press the RED RESET SWITCH and, while holding it down, recon-
nect power to the unit, that is, power up the unit with the reset
switch ON.
5.
After the DECmux II unit has completed its diagnostic tests (indi-
cated by the GREEN indicator on the front of the unit), remove
power and replace the top cover.
The unit has now been reset to factory default values.
Following the reset procedure, the supervisor port PASSWORD on the
DECmux II is "SYSTEM". To maintain security you should change this pass-
word. (See Section 2.2, SETTING UP THE PRIVILEGED PASSWORD.)
