Setup Guide
NOTE: To remove the power connector from a DC PSU, squeeze the 
levers on both sides of the connector. Doing so disengages the power 
connector’s clamps. While continuing to squeeze, pull the power 
connector from the DC PSU socket.
Installing a Fan Module
CAUTION: DO NOT mix airflow directions. All fans must use the same 
airflow direction (I/O to Utility or Utility to I/O).
CAUTION: Check the fans at six-month intervals and replace them as 
necessary. To accurately determine replacement intervals, regularly 
monitor the speeds of the cooling fans.
1. Remove the fan module from the shipping box.
2. Use the grab handle and the orange tab to slide the module into the 
switch fan slot.
