ASSEMBLY (-202) AND FAN UPGRADE KIT (-203).

2. THE –202 CONFIGURATION IS FOR FIELD REPLACEMENT OF THE FAN ONLY.

3. THE -203 CONFIGURATION IS FOR FAN UPGRADE ONLY, IT CHANGES THE FOUR SMALL FANS FOR ONE LARGE FAN

AND IS THE REPLACEMENT FOR AEGIS FAN TRAY ASSEMBLY PART NUMBER BA2809FT USED ON AEGIS POWER SUPPLY PART NUMBER BA2809. IT INCLUDES THE FAN TRAY ASSEMBLY (-202) AND HARNESS (-204). IT ALSO INCLUDES 1 PIECE OF SHRINK TUBING FOR COVERING THE HARNESS (-204) WHERE IT ATTACHES TO THE POWER SUPPLY AND FOUR SCREWS (#6-32 X .186 LONG) FOR MOUNTING THE TRAY TO THE POWER SUPPLY.

4. THE -204 CONFIGURATION IS ONLY USED FOR POWER SUPPLIES UPGRADED WITH THE FAN UPGRADE KIT (-204). IT WILL NOT BE SUPPLIED WITH THE NOA301 POWER SUPPLY ASSEMBLY (-201), THAT CONFIGURATION WILL HAVE

THE HARNESS HARDWIRED INTO THE POWER SUPPLY.
