3.
Ensure that the voltage across the DC power source cable leads is 0 V and that there
is no chance that the cable leads might become active during installation.
4.
Using both hands, slide the PSM straight into the chassis until the PSM is fully seated
in the chassis slot. Tighten the two captive screws to secure the PSM to the chassis.
NOTE:
The MX2010 systems configured for DC input power must use only
DC PDMs and DC PSMs. AC and DC PSMs or PDMs must not be mixed
within a single system.
5.
Verify that the
INP0
or
INP1
LEDs on the PSM are lit green steadily. The
INP0
or
INP1
LEDs will be lit yellow if that input’s voltage is in reverse polarity. Check the polarity
of the power cables to fix the condition (see
and
).
6.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
7.
Move the switch to the on (
|
) position.
8.
Verify that the
PWR OK
LED is lit green steadily. See
for information
on MX2010 DC PSM LEDs.
