Safety and Enviro nm e nt al Gu id elines
The Passport 8002PS DC Power Supply converts ±48 VDC or ±60 VDC input into separate DC
outputs to the chassis backplane. The input voltage range is
current of 25 A (at 48 VDC) or 20 A (at 60 VDC).
For branch circuit over-current protection for the DC power source, check your national code
requirements. For U.S. installations, follow NEC articles 422-28(e) and 422-30.
The Passport 8000 Series switches are designed to operate in ambient temperatures of 0
° to 104° F) with a relative humidity of 10 percent to 85 percent (noncondensing).

±42 to ±66 VDC with a maximum input
° to 40° C
Equipment with DC power supplies should be installed only in areas with limited access, such as
dedicated equipment rooms.
Caution: The DC power input source for the Passport 8002PS DC Power Supply must be
restricted to an ou tput tha t is li mited to Sa fety Extr a Low Voltage (SELV) output per IEC950
Definition. This input power source must be reliably connected to ground and electrically
isolated from the AC source.

Preparing Cables
Required tools: Crimping tool for crimping lugs onto cables; heat gun
Nortel Networks does not supply the cables for connecting the Passport 8002PS DC Power Supply to
the DC input power source. You can therefore select cables that comply with the electrical code of the
country where you intend to use the DC power supply.
The following items are shipped with the Passport 8002PS DC Power Supply:
• Two 2-hole crimp lug terminals with attached heat-shrink
tubing (1) for connecting the positive and negative power
1
inputs
• One 1-hole crimp lug terminal with attached heat-shrink
tubing (2) for connecting the ground stud
2
• Five lock washers for connecting all leads
• One lock washer for connecting the ground stud
Caution: As the installer, you have the sole responsibility to ensure that the connection
cable used with the Passport 8002PS DC Power Supply is appropriate for use with the DC
power source to which the power supply is connected. Consider gauge, flammability, and
mechanical serviceability when determining which cables to use.
To select and prepare cables for connecting the power supply, use the following guidelines:
• Use a 6-gauge, 3-conductor cable such as an SOW-A, Type 90C
or equivalent.
• Use cable that accommodates the supplied DC input and frame

ground crimp lugs.
• To connect to the positive and negative terminal leads, use the
two-hole lug terminals (1).

• To connect the frame ground lead, use the one-hole terminal (2).
• Strip the outer cable jacke t to no less than 1 1/2 inch (3.8 cm) to
expose the insulated conductor cables within.
• Strip the insulated conductor cables inside the outer jacket to
0.81 in (2.1 cm).
• Use a standard crimping tool to crimp the lugs onto the cables.
Failure to properly crimp the lugs onto the cables constitutes a
safety hazard.
• If necessary, use a heat gun t o s hrink the t ubing around the cabl e.

Operational Notes
A Passport 8000 Series Chassis with up to five in stall ed modules can operate with one insta lled power
supply. For a redundant power configuration, install two power supplies.
A Passport 8010 Chassis with more than six installed modules requires a minimum of two power
supplies for a nonr edu ndan t configuration. A red unda nt configuration for su ch a ch assis requires thr ee
power supplies.
In a chassis with a nonredundant power supply configuration, if one power supply fails, the system
may lose power and network connectivity.
In a chassis with two installed power supplies, you can add a third power supply without powering
down the chassis. The Passport 8002PS DC Power Supply is hot-swappable.
When you first install a Passport 8000 Series Chassis that requires two power supplies (nonredundant
configuration), you must turn on both power supply units within 2 seconds of each other. If you wait
longer to turn on the second power supply, both power supplies will shut down. To correct this
condition, turn of f bot h powe r supplies, wait at least 30 sec onds, and then turn on both power supp li es
again within 2 seconds.
If the DC input power source is below 2400 W, you may want to have a se par at e in put source for each
power supply.
Installing a Power Supply
Required tools: Phillips screwdriver, 7/16-inch wrench

1. If necessary, remove the filler pa nel from a
power supply bay.
2. Check to be sure the power switch is in the
9430FA
off position (down).

3. Push the power supply partway into the bay.
Leave the terminal block at the side of the
power supply exposed.
Note: If you are installing a power supply in a new chassis, be sure to remove the bag of
moisture-absorbing material from the middle power supply bay.
Warning: Make sure the DC power source is off or disconnected on the remote end before
you connect the te rminal l eads to t he power s upply. You may need to s witch a circui t breake r
or turn off the DC input power source.

6. Attach the grounding cable to the system or
rack ground for your DC i nput power source.
8. Attach the positive and negative terminal
leads to the DC input power source
according to the proper safety and technical
specifications for your 48-volt power
distribution system.
7. Firmly slide the power supply all th e way
into the bay and tighten the retaining screws.
9. Turn the DC input power source on, or reset
the power source circuit breaker, to provide
power to the power supply.
10. Turn the power supply switch to the
on position.

Removing a Power Supply
Required tools: Phillips screwdriver, 7/16-inch wrench
In a chassis with a redundant power supply configuration, you can replace or install a power supply
without powering down the chassis.
1. Turn off the power switch on the power
supply you are replacing.
3. Disconnect the positive and negative
terminal leads from the DC input power
source.
2. Disable the incoming power from the DC
input power source. You may need to switch
a circuit breaker or turn off the DC input
power source.
Warning: Make sure the DC power sour ce
is off or disconnected at the remote end
before you remove the power supply.
4. Disconnect the grounding cable from the
system or rack ground of your DC input
power source.
