1 Introduction
Welcome to the Dual Feed DC Telecom Power Supply User’s Guide. This guide contains information
about the installation and use of Continuous Computing Corporation’s 100W, 150W, and 350W Dual
Feed DC Telecom Power Supplies.
This guide includes the following information related to the 100W, 150W, and 350W Dual Feed DC
Telecom Power Supplies:
• Unpacking, installing, and starting up
• Grounding your system
• Troubleshooting
• Connector usage and specifications
Description
The Continuous Computing Telecom Power Supply offers 100, 150, or 350 watts of Hot Swappable,
load-sharing power for a CompactPCI system. The Power Supply is designed for the Central Office,
with dual input feeds and –48V DC input. Typical systems combine two Supplies to provide redundant
power. Each Power Supply also provides a standby power output for use by a Continuous Control Node
(CCN).
Features of the Dual Feed DC Telecom Power Supply include:
• Hot Swap and Load Sharing
The Power Supply is designed for redundant operation. A failed Power Supply can be
replaced without application downtime. Load sharing ensures that supplies run cooler,
leading to increased system reliability.
• Standby Power
Standby power provides an output that is always on to power a Continuous Control Node.
This enables remote power cycling and system diagnostics even when the Power Supply is
off.
• Over Temperature and Short Circuit Protection
Protection features reduce the possibility of hardware damage during extreme temperatures
or fault conditions.
• Remote Sense on +5 and +3.3V
Remote sense provides high-quality power to critical system components.
• Dual Input Feeds
Dual power feeds allow the system to continue running even if one feed drops out.
• 6U CompactPCI Form-Factor
Standard 6U form-factor allows for easy integration into CompactPCI system without
awkward divider rails.
The Telecom Power Supply is a Basic Hot Swap device. PICMG 2.1 R1.0 describes Basic Hot Swap as
a board powered and enabled for access by the PCI bus in configuration space only upon insertion. The
board’s configuration space is not yet initialized. You must initiate software connection at the system
console. The power circuitry is controlled so that inserting in or extracting from a live redundant system
will not cause any electrical damage. If the system is not redundant, it must be halted before servicing.

4 Troubleshooting
Troubleshooting Scenarios
In the event that the Power Supply should fail in any way, use the following procedures to troubleshoot.
Note: The Power Input Module contains only passive components and therefore is extremely unlikely to
be the cause of failure.
Check the LEDs
If the INPUT LED is not on, one or more of the following applies:
• The -48V source has not been enabled externally.
• The Power Input Module is not correctly connected or the cables bringing power have
improper polarity.
• Both the Feed A and Feed B fuses have blown on the Power Supply. Use the “Check the
Fuses” procedure below to determine if the fuses have blown.
If the FLT LED is on, one or more of the following applies:
• One of the fuses, or both, have blown. Use the “Check the Fuses” procedure below to
determine if the fuses have blown.
• Feed A or Feed B, or both, have lost power from the external source.
• The onboard converters have failed.
Note: The FLT LED will light only if the CCN is connected.
Use the Command Line Interface (CLI) or the GUI to the CCN to further troubleshoot the Power
Supply and find out whether the problem is external or internal. See the section below, “Use the CCN,”
to troubleshoot from the CLI.
Use the CCN
If the above conditions have been checked and do not solve the problem, you can use the CCN to
investigate the status of the Power Supply. If the CCN is receiving alarm power from a redundant
Supply within that system, or from a crossover connection of alarm power from the opposite side of the
system—even if a Power Supply is dead—the CCN can still be used to determine problems with the
Power Supply.
Use the faults command
First, login to the CCN and type faults. The faults command shows what is active at the time,
indicating one or more of the following: a Feed A fault, a Feed B fault, or a power converter fault. The
output from the faults command will look as follows:
samplesys ccncli> faults
# ST Description
1 L Sampled ALM12A out of range (use 'voltages')
2 L Sampled ALM12B out of range (use 'voltages')
8 A Power Supply A not present
9 A Power Supply B not present

Continuous Computing Corp. Page 20 File: CC00313-00

10 L Disk A not present
16 L Power Supply A 48V feed A no power
17 L Power Supply A 48V feed B no power
20 L Power Supply B 48V feed A no power
21 L Power Supply B 48V feed B no power
27 A Application heartbeat not received within timeout period
samplesys ccncli>
Note: If the condition causing the fault is current, then the fault is “active”. Once the condition has been
corrected, then the fault is “latched”. Faults can be cleared using the faults reset command.
If the power switch on the CCN is used to turn the Supply on or off and the Power Supply’s ON LED
does not come on when it should, a communication problem between the CCN and the Power Supply
has occurred. Therefore, either the CCN or the Power Supply will need to be replaced. To determine
which is defective, first try swapping in another Power Supply. If the new Supply does not work, try
swapping in another CCN. By doing so, you will be able to figure out if the communication problem is
due to the Supply or the CCN.
Use the voltages command
If the above does not solve the problem, try using the voltages command on the CCN to determine
whether the currents or temperature are out of range. The voltages command lists all sampled
voltages and temperatures along with the minimum and maximum values since the last voltages
reset command (which clears all of the stored min/max values). In addition, the allowable upper and
lower limits for each sampled voltage or temperature are displayed.
Output Indicates
TEMP0 The temperature within the
chassis.
ALM12A and ALM12B The CCN power feeds
(ALM12B is only present in
multi-node systems).
TEMP1 An extra sensor that is typically
not connected.
(the remaining voltages) The CompactPCI midplane
voltages.
Table 7 voltages command outputs
Check the Fuses
1. If your system uses a single Power Supply, halt the operating system.
2. Remove the Power Supply from the system. To do this, use the “Removing the Power Supply”
procedure below.
3. Using the photo of your Power Supply (see Figure 2, Figure 3, or Figure 4), locate the Feed A
and Feed B fuses on your board.
4. With a continuity meter check the fuse on the card. If one or both fuses are blown, return the
Power Supply to Continuous Computing Corporation for analysis and repair.
