• When installing equipment into a rack, distribute
the units evenly. Otherwise, hazardous conditions
may be created by an uneven weight distribution.

• To turn off the main power, be sure to remove
the adapter from the power outlet. The power
outlet socket should be installed as near to the
equipment as possible, and should be easily
accessible.
• Do not pull the adapter or any cable that is
attached to the DA1921SX.
• If the DA1921SX is not used for an extended
period, disconnect the adapter from the outlet.
