Size: 19" (483 mm) Rackmount standard front panel
17" (432 mm) chassis width
12.25" (311 mm) High
22" (559 mm) Deep + 5" (127 mm) for cables
2.15 Cooling Water
Maximum exit temperature for cooling water at approximately 2.0 US gpm (7.6 L/min) is 35°C
Minimum exit temperature for cooling water at approximately 2.0 US gpm (7.6 L/min) is 15°C
(Higher temperature water requires greater flow). All water paths are at ground potential and are
copper or brass.
