Operation
FUNCTION SWITCH ELECTRICAL DESCRIPTION
The function switch has four positions:
Two Read/Write (RW). The hard
disk can be fully accessed by the
host computer. There is no front
panel LED to indicate this position.
Two Read-Only (RO). The orange
Read-Only LED will be lit.
NOTE: Refer to the TranzPak 6 User
Manual for details about
system operations.
NOTE: Some disk manufacturers
require that the power to the
disk be cycled after setting it
to a write-protect mode in
order to use the write-protect
feature. The only way to
determine if the disk requires
power-down to change to
Read-Only is to turn the
function switch to a RO
position, then try to write to
the disk.
FUNCTION SWITCH VERSIONS
The function switch has two modes:
Handle locked
Handle unlocked
The function switch also has two
versions:
Knob
Key lock
The switch functions identically in
both versions. The only difference is
that with the key lock version, a key is
required to be inserted into a lock in
order to change the position of the
switch.
LOCKING THE DISK MODULE AND HARD DISK
On the disk module front panel on
each side of the word SECURITY
there are small padlock icons.
The left icon indicates an unlocked-
handle mode when the function switch
is in one of its two left positions (either
RW or RO). The right icon indicates a
locked-handle mode when the
function switch is in one of its two right
positions (either RW or RO).
