RNAS-1200 Series Enabling IHS™
11-3
Step 3: To switch the IHS mode, adjust the jumpers to one of the configurations shown below.
TX Mode (-40 to -25°C):
System Default
This mode is for the most extreme
environments, and requires the most
rugged drive hardware. Over the course of
20 minutes, TX mode heats the drive to
-25°C and then automatically powers up
the system.
T1 Mode (-25 to 0°C)
T1 is for environments that often fall below
freezing, but do not go below 25°C
; it also
requires industrial-grade drive hardware.
Over 45 minutes T1 mode will heat the
HDD to 0°C and then power on the system
.
Disabled:
To entirely disable IHS, r
emove all jumper
covers. This will completely turn off the
heating system so that no automated
heating processes will be active.
Step 4: Replace and secure the hard disks and chassis to complete the IHS configuration.
