Connect AC Power to a PA-7050 Firewall

This topic describes how to connect power to a PA-7050 firewall with AC power supplies installed. The
power supplies require 120VAC 15-amp or 240VAC 20-amp power input. For details on power
requirements, see "Determine Power Configuration Requirements" on page 70.
1. Read "Cautions and Warnings Related to Working with the Hardware" on page 89 and for power
configuration planning, see "Determine Power Configuration Requirements" on page 70.
2. Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your
skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator clip
from the banana clip on the other end of the ESD grounding cable. Plug the banana clip end into
one of the ESD ports located on the front of the chassis before handling ESD sensitive hardware.
For details on the ESD port location, see "PA-7050 Front Panel (AC)" on page 6 or "PA-7080
Front Panel (AC)" on page 13.
3. Ensure that all AC power switches are in the off position.
4. Remove the two nuts and star washers from the ground studs located on the back of the chassis on
the upper left side.
5. Crimp a 6-AWG wire to the provided grounding lug and connect the other end to your earth ground
point.
6. Connect the two-post lug connector to the two-post ground studs on the chassis using the provided
star washers and nuts and then torque the nuts to 50 in-lbs. Be careful not to strip the nuts and
studs.

7. Connect the first two power supplies to a 120VAC 15-amp circuit breaker or 240VAC 20-amp
circuit breaker using the provided power cords and then connect the second two power supplies to
a second, independent 120VAC 15-amp circuit breaker or 240VAC 20-amp circuit breaker.
Note: If you connect 120VAC power and you install five or six NPCs in a PA-7050
firewall or ten NPCs in a PA-7080 firewall, you can configure only partial
redundancy. Full redundancy is not possible because the chassis do not hold twice
the minimum number of active 120VAC power supplies required to power the
chassis and the NPCs.
8. Secure the power cords to the power inlets using the power cord retainer clips.
9. Ensure that all front slot cards are properly inserted and then turn on each of the four AC power
switches located on the back of the chassis. The chassis will power on.
