1.
Attach the
ESD-preventive wrist strap to your wrist and connect its leash to one of the
ESD connection sockets on the front (SFC) side of the chassis or a bare metal
surface on the chassis.
2.
Make sure that
the safety ground wiring is connected.
3.
Make sure that
the facility power breakers for the upper (PS0) and lower (PS1)power shelves
are in the OFF position.
4.
Make sure that
all the I/O switches are in the OFF position. That is, make sure all I/O levers
are pulled out. There are total of six I/O levers for the AC power rectifiers
(one for each of the six AC rectifiers) and two I/O levers for the AC power
shelves (one for each power shelf).
5.
Make sure all
SFCs are pulled-out and disconnected from the backplane.
6.
Remove the
cover plate from the rear of the AC power shelves.
7.
Plug in AC
power cords.
8.
For AC Delta
and AC wye, verify the following resistance values (see
Figure 1
and
Figure 1):
9.
Make sure that
each input power cable is connected, and energize the facility breaker to each
input.
10.
Measure the
voltage between the following:
11.
Turn the
facility breaker for the upper power shelf (PS0) to the OFF position. Repeat
for the facility power breaker for the lower power shelf (PS1).
12.
Turn the
facility breaker for the upper power shelf (PS0) to the ON position. Repeat for
the facility power breaker for the lower power shelf (PS1).
13.
Turn the power
shelf I/O switches on both power shelves (PS0 and PS1) to the ON position.
Verify that the “CBREAKER TRIP” LED on the front panel of each power rectifier
is yellow and that no other LEDs are active.
14.
Turn the first
power rectifier (A0; see
Figure 1)
power switch on the upper power shelf (PS0) to the ON position. Verify that the
“PWR OK” LED on the power rectifier (A0) front panel is green and that no other
LEDs are active. Repeat for the other two rectifiers (A1 and A2; see
Figure 1).
15.
Turn the first
power rectifier (B0; see
Figure 1)
I/O switch on the lower power shelf (PS1) to the ON position. Verify that the
“PWR OK” LED on the power rectifier (B0) front panel is green and that no other
LEDs are active. Repeat for the other two rectifiers (B1 and B2; see
Figure 1).
16.
Turn the I/O
switches on all power rectifiers and both power shelves to the OFF position.
Verify that no LEDs on the power rectifier front panels are active.
17.
Insert all
boards into the chassis (see
Installing and Removing Fabric Cards and Card Components
chapter).
18.
Turn the power
shelf I/O switches (PS0 and PS1) to the ON position.
19.
Turn all power
rectifier I/O switches to the ON position.
20.
Measure the
input voltage of each input and compare this value to the voltage measurement
noted in step 7. Verify that the voltage is between 200 to 240 VAC, ensure that
the voltage drop is within the acceptable limits for your site.
21.
Turn the I/O
switches on all power rectifiers and both power shelves to the OFF position.
Turn the facility breaker for the upper power shelf (PS0) to the OFF position.
Repeat for the facility power breaker for the lower power shelf (PS1).
22.
Replace the
cover plate on the rear of the AC power shelves.
23.
Turn the
facility breaker for the upper power shelf (PS0) to the ON position. Repeat for
the facility power breaker for the lower power shelf (PS1).
24.
Turn both power
shelf I/O switches (PS0 and PS1) to the ON position. Turn all power rectifier
I/O switches to the ON position.
To power down the
chassis entirely, you must power down both of the power shelves by moving the
power shelf I/O switch to the OFF position by lifting up on the lever and
pulling it out. Both power shelves must be disconnected to de-energize the
chassis completely.
This table shows
the meaning of the LED status lights on the front panel of the AC power
rectifiers in the fixed configuration power system.
