POWER-UPSEQUENCE
When the LPS-APU-L1 powers up, do the following:
1Check the PWR LED located on the front panel.
aIf the PWR LED lights green, both the A and B power sources are working
properly. Proceed to Step 2.
bIf the PWR LED lights red or is off, check the power sources. If they are
both supplying -48 Vdc to the chassis at the power terminal block, the
LPS-APU
isdefective.Removethe
LPS-APU
and repeat this procedure with
a new unit.
2Press the LMPTST pushbutton.
aIf all the LEDs light, the installation is complete.
bIf any LED does notlight on the
LPS-APU nor on theline cardsin the chassis
