Note: Software checks: If the total power provided by the power
supplies falls below the switch requirement, the polling software
displays the following message on the console: chCheckPowerUsage:
One or more cards running low on power.
The total power used by the switch and the total amount of power
provided by the power supplies can be seen by using the "show sys info"
command or by accessing the chassis/edit menu in Device Manager.

Note: The 8010co equipment shelf load and 8004DC power rating shall
be limited to 732w per power supply when configured with the 8010co
BIP. The product configuration limitation is required to be in
compliance with the electrical code, because of the difference between
the 8010co BIP output circuit protection rating of 30A and the 8004DC
power supply input current rating of 29A at -48Vdc nominal operating
condition.
Note: The 8002DC power supply is discontinued. The 8004DC or
8005DC power supply replaces the 8002DC power supply.
Caution: The 8004DC and 8005DC power supplies have different
power ratings. Therefore, Nortel recommends that you do not operate the
Ethernet Routing Switch 8600 chassis with a mix of power supply
models.
313070-E Rev 00
If you are upgrading the Ethernet Routing Switch 8600, and have a
redundant power configuration, you can hot-swap the 8004DC power
supply with the 8005DC power supply while the Ethernet Routing
Switch 8600 system remains in operation. Do not operate the chassis
with a mix of power supply models for an extended period of time.
Upgrade power supplies before upgrading modules.
Tabl e 2 describes the power supply LED on the DC power supply.

The 8000 Series chassis ships with no installed power supplies. Install the first
power supply in the leftmost bay. Power supply bays are numbered 1, 2, and 3 left
to right as viewed from the front of the chassis for the 8006, 8010, and 8010co.
For instructions on how to install the power supplies, see “Installing the DC power
supply” on page 32.
The 8002DC power supply is discontinued. The 8004DC or 8005DC power
supply replaces the 8002DC power supply. For information on the 8002DC power
supply, see the Ethernet Routing Switch 8600 Software Release 4.1
documentation.
Note: The 8002DC power supply has not been tested with Ethernet
Routing Switch 8600 modules released since 8600 Release 3.7.
Therefore, Nortel recommends that you use the 8004DC or 8005DC
power supply with these modules.
8004DC power supply
8000 Series DC power supplies 21
Each 8004DC power supply provides 850 watts (W) of power to the switch.

Determining the minimum number of 8004DC power supplies to install
When configuring an Ethernet Routing Switch 8600 system, you should consider
total power consumption to ensure proper system performance.
313070-E Rev 00
The total input power-consumption of the components (modules and fan trays)
must not exceed the output power rating of the 8004DC power supply (850W).
To determine the minimum number of power supplies to install for the Ethernet
Routing Switch 8600 system:
1 Add the total (3.3 V and 12 V) input power consumption (wattage) for all
components (modules and fan tray assemblies). See “Technical specifications
for the Ethernet Routing Switch 8600 Chassis” in Installing and Maintaining
the Ethernet Routing Switch 8600 Chassis.
2 Refer to the output power rating of the 8004DC power supply. For the
8004DC power supply specifications, See Appendix A, “Technical
specifications for the DC Power Supply,” on page 57.
8000 Series DC power supplies 23
If either the individual or combined power for the components exceed the
output power rating of the power supply, you need to add at least one more
power supply to your configuration.
3 Consider your redundant power supply needs. If one power supply satisfies
your system power-consumption needs, a second power supply provides
redundancy. If two power supplies satisfy your system power consumption
needs, a third power supply provides redundancy.
Redundant power configuration
If a chassis has a redundant power configuration and one power supply fails, the
chassis continues to operate with no interruption of service. The chassis will
continue to supply the same module output power with the remaining power
supplies. A trap and syslog message will indicate that the configuration is
non-redundant. Nortel recommends that you operate the Ethernet Routing Switch
8600 system in a redundant configuration at all times to ensure maximum network
up time.
If a chassis has the minimum power supply configuration and one power supply
fails, the system loses power and network connectivity.
Note: Nortel recommends that you install each power supply on its own
dedicated branch circuit. This ensures that a fault on another branch
circuit doesn’t cascade onto other branch circuits.
A redundant power supply provides protection against the failure of
another power supply in the system.

2 Refer to the output power rating of the 8005DC power supply based on the
input connection. See Appendix A, “Technical specifications for the DC
Power Supply,” on page 57.
If either the individual or combined power requirements for the components
exceeds the power supply rating, you need to add at least one more power

34 Adding and replacing DC power supplies
Preparing cables
Nortel does not supply the cables for connecting the DC power supply to the DC
input power source. Select cables that comply with the electrical code of the
country where you will use the DC power supply.
Caution: You have the sole responsibility of ensuring that the
connection cable used with the 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.
If you ordered the optional breaker interface panel (BIP), Nortel ships the cables
for connecting the BIP to the 8004DC power supply. Go to “Installing the power
supply” on page 36.
To prepare cables for connecting the power supply:
1 Strip 0.81 in. (2.1 cm) of insulation from the ends of the cables. See Figure 8
for 8004DC. See Figure 9 on page 35 for 8005DC.

Note: Due to the N + 1 power sharing architecture, if your chassis
contains two or three non-redundant power supplies, Nortel recommends
that you turn on the power supplies simultaneously. If you wait longer to
turn on the supplies, the power supply(s) shut off within 7 seconds. To
correct this condition, turn off the power supplies for a short period of
time, and then turn on the power supplies again simultaneously.
If the LED on the power supply does not turn on, contact the Nortel Technical
Solutions Center.
Adding and replacing DC power supplies 45
Removing the DC power supply
You can remove a redundant power supply without affecting the operation of the
8600 Series switch. When you remove a power supply, the LED on the power
supply turns off, and the 8000 Series chassis automatically redistributes the load
to the remaining power supplies.
Caution: To maintain proper cooling, never operate the chassis with an
empty power supply bay. If you are replacing a failed power supply and
you do not have a power filler panel, leave the failed power supply
installed until a replacement power supply is available.
To remove a DC power supply:
1 For the 8010co chassis, remove the bottom front bezel.
For instructions, see “Removing the bottom bezel (8010co chassis)” on
