Power Supply Test Points
There are four test points on the front edge of the power supply modules. When
checking the test points, test both the main and redundant supplies. The approximate
range of voltages that may be expected at these points is listed below. Voltages outside
of listed ranges may indicate a bad power supply module; replace with a known good
module.
Table 4. Power Supply Test Points
PS TEST POINT DC VOLTAGE RANGE
+7 +6.0 to +8.0
-7 -6.0 to -8.0
+15 +13.0 to +16.0
-15 -13.0 to -16.0
Warning: Power supply components may be hot when the power supply has been
operating. To prevent burns, do not touch components when removing power supplies.
