RNAS-1200 Series Enabling IHS™
11-2
Setting Up IHS
The RNAS-1200 offers an Intelligent Heating Solution™ (IHS) to ensure the system will work reliably even in
extremely low temperatures. IHS is an automated, onboard heating system that will heat a hard disk or solid
state storage drive to a preset temperature. If the RNAS-1200 is booted up and the system senses the
environmental temperature has dropped to below freezing (zero degrees Celsius / 32 degrees Fahrenheit), the
RNAS-1200 may heat the system to either -25°C (TX mode) or 0°C (T1 mode), depending on how the utility is
configured.
The system ships with IHS TX mode already enabled. To function properly, IHS requires storage drives
specifically designed for harsh environmental conditions. In industry literature these types of drives are often
called “automotive grade.” Below is a list of drives which are currently (Oct. 2012) approved for use on the
RNAS-1200 system. This list will be continuously updated as Moxa’s technical support teams verify new drives
for approved use, so to find the most recent list of approved drives you may visit the Moxa RNAS support
documentation pages, or attempt to download the file directly from this link

The IHS TX mode is for the most severe cold weather environments. This requires a specially manufactured
industrial-grade storage drive (such as some of the Hitachi Endurastar or Toshiba MKxx60GSC products)
designed for environmental extremes. When configured for TX mode, upon detecting external temperatures
that is less than -25°C the RNAS-1200 will, over the course of 20 minutes, heat the system to -25°C and then
automatically boot up the system.
The design requirements for IHS T1 mode are not so severe as those for TX mode. When configured for T1
mode, upon detecting external temperatures that is less than 0°C the RNAS-1200 will, over the course of 45
minutes, heat the system to 0°C and then automatically boot the system.
To set up the RNAS-1200 for IHS T1 or TX mode (or to disable IHS), you will need to access the RNAS PCB to
set the onboard jumpers. The steps below describe how to configure the onboard IHS jumpers.
Step 1: Remove the screws and the top cover of the RNAS-1200. To review how this is done, please refer to
the manual section Installing the Storage Drive.
Step 2: Remove the hard disk on the right side to expose the location of jumper J16. Please see the photo at
the top of the next page for a detailed picture of where the J16 jumper series is located.
ATTENTION
Please note that
for the RNAS-1201 and RNAS-1211 models TX mode is the system default
. Unless you
have installed suitably engineered hard disks, you will need to switch the system to either disable IHS or switch
it to T1 mode
. Using TX mode with commercial grade hard drives in cold weather may result in severe and
irreversible damage to your
storage drives.
