(part number 204518-B) and Installing the Passport 8006 Chassis (part number 207313-B).  
Safety and Environmental Guidelines  
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 42 to 66 VDC with a maximum input  
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 40° C  
(32° to 104° F) with a relative humidity of 10 percent to 85 percent (noncondensing).  
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 output that is limited to Safety Extra 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  
inputs  
1
2
One 1-hole crimp lug terminal with attached heat-shrink  
tubing (2) for connecting the ground stud  
9413EB  
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.  
1
Use cable that accommodates the supplied DC input and frame  
ground crimp lugs.  
2
3
5
To connect to the positive and negative terminal leads, use the  
two-hole lug terminals (1).  
4
To connect the frame ground lead, use the one-hole terminal (2).  
>
1.5 in.  
(3.8 cm)  
Strip the outer cable jacket to no less than 1 1/2 inch (3.8 cm) to  
expose the insulated conductor cables within.  
9414EA  
1 = Insulated Conductors  
2 = Frame Ground  
3 = Negative (-)  
4 = Positive (+)  
5 = Outer Insulation Jacket  
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 to shrink the tubing around the cable.

Operational Notes  
A Passport 8000 Series Chassis with up to five installed modules can operate with one installed 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 nonredundant configuration. A redundant configuration for such a chassis requires three  
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 off both power supplies, wait at least 30 seconds, and then turn on both power supplies  
again within 2 seconds.  
If the DC input power source is below 2400 W, you may want to have a separate input source for each  
power supply.  
Installing a Power Supply  
Required tools: Phillips screwdriver, 7/16-inch wrench

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

9412FA  
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 terminal leads to the power supply. You may need to switch a circuit breaker  
or turn off the DC input power source.

5. Attach the positive and negative voltage  
leads to the positive and negative terminals  
on the power supply.  
4. Attach the grounding cable to the ground lug  
on the power supply.  
Use the washers in this order:  
Use a lock washer between the crimp lug and  
each hex nut.  
Flat washer  
Crimp lug  
Lock washer  
Hex nut  
Use a 7/16-inch wrench to tighten the hex  
nut on each terminal.

6. Attach the grounding cable to the system or  
rack ground for your DC input power source.  
7. Firmly slide the power supply all the way  
into the bay and tighten the retaining screws.  
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.  
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.  
9430FA  
1. Turn off the power switch on the power  
supply you are replacing.  
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 source  
is off or disconnected at the remote end  
before you remove the power supply.  
3. Disconnect the positive and negative  
terminal leads from the DC input power  
source.  
4. Disconnect the grounding cable from the  
system or rack ground of your DC input  
power source.
