What is the LightStream 1010 ATM Switch?
The LightStream 1010 uses a five-slot, modular chassis featuring the option of dual, fault-tolerant,
load-sharing power supplies. (See Figure 1.) The central slot in the LightStream 1010 is dedicated
to a single, field-replaceable ATM switch processor (ASP) module that supports both the 5-Gbps
shared memory and the fully nonblocking switch fabric. The ASP also supports the feature card and
high performance reduced instruction set (RISC) processor that provides the central intelligence for
the device. The remaining slots support up to four hot-swappable Carrier Modules (CMs). Each CM
supports up to two hot-swappable Port Adapter Modules (PAMs) for a maximum of eight PAMs per
switch, supporting a wide variety of desktop, backbone, and wide-area interfaces.

Power Supplies
Power Supplies
The LightStream 1010 ATM switch comes equipped with one power supply. This power supply may
be either an AC or DC input version. An identical, optional, second power supply is also available
for fault-tolerant power. Dual power supplies are automatically load-sharing and redundant, which
means that a second power supply can be installed or replaced without interrupting system operation.
Fault-Tolerant Power
When two power supplies are installed and both are turned on, each concurrently provides about half
of the required power to the system. If one of the power supplies fails, the second power supply
immediately ramps up to full power to maintain uninterrupted system operation. Load-sharing and
fault-tolerance are automatically enabled when the second power supply is installed; no software
configuration is required.
Each power supply should be connected to a separate AC or DC sources so that, in case of an input
power line or power supply failure, the second power supply maintains uninterrupted system power.

Power Supply LEDs
Each power supply has one LED. The LED is green when the power supply is powered on and
operating within tolerances. The LED is off when the power supply is powered off, the power cord
is disconnected, or if the power supply has malfunctioned.
See the following section for a description of the PS0 and PS1 LEDs on the ASP.
ATM Switch Processor Power Supply LEDs
On the ATM switch processor front panel, the PS0 LED goes on when the power supply in the left
bay, labeled Power Supply 0, is installed and supplying power to the system. The PS1 LED goes on
when the power supply in the right bay, labeled Power Supply 1, is installed and supplying power to
the system. Both the LEDs should be on in systems with redundant power. The ATM switch
processor LEDs are shown in Figure 4 and described in Table 2.

If the left bay power supply is operational, the PS0 LED is green.
If the left bay power supply is turned off or not operational, the PS0 LED is red.
If the left bay power supply is not installed, the PS0 LED is off.
PS1
If the right bay power supply is operational, the PS1 LED is green.
If the right bay power supply is turned off or not operational, the PS1 LED is red.
If the right bay power supply is not installed, the PS1 LED is off.
Power Supply LED
The green LED (see Figure 5) indicates the status of the power supply and internal DC voltages. The
LED stays on when the power supply is on and receiving source power, providing +5, +12, and +24
VDC to internal components, and ensuring all internal voltages are within tolerance.
If the source power or any of the internal DC voltages exceed allowable tolerances, the LED goes
off and the system environmental monitor messages indicate the out-of-tolerance line. Because the
system requires all three output voltages for operation, the system will probably malfunction or shut
down if any of the internal DC voltages reach an out-of-tolerance state.

Overvoltage and Overtemperature Protection
The power supply monitors its own temperature and internal voltages. If the supply detects an
overvoltage or overtemperature condition, it shuts down to avoid damage to the power supply or
other system components.
Note If the power supply shuts down, wait for the supply to cool, then turn the power switch off
(0), then on (–). If the power supply shuts down again, remove and replace it.
Installing and removing either AC or DC power supplies is described in the following sections:
•
•
Removing and Installing AC Power Supplies
Removing and Installing DC Power Supplies
Power Supply Monitoring
The power supplies are self-monitoring. Each power supply monitors its own temperature and
internal voltages.
Environmental Monitoring and Reporting Functions
The environmental monitoring and reporting functions enable you to maintain normal system
operation by identifying and resolving adverse conditions before the system fails. Environmental
monitoring functions constantly monitor the internal chassis air temperature. Each power supply
monitors its own voltage and shuts itself down if it detects a critical condition within the power
supply. The reporting functions enable you to retrieve and display the present values of measured
parameters, and the reporting functions display alarms on the console if any of the monitored
parameters exceed defined thresholds.
Environmental Monitoring
The environmental monitoring functions use three levels of status conditions to monitor the system:
normal, alarm, and critical. The processor monitors the temperature inside the module compartment,
and the power supplies use the normal and critical levels to monitor DC voltages. Table 3 lists
temperature thresholds for the processor-monitored levels. Table 4 lists the DC power thresholds for
the normal and critical power-supply-monitored levels.
Table 3
Processor-Monitored Temperature Thresholds

The three levels of status condition includes:
•
•
Normal—all monitored parameters are within normal tolerances.
Alarm—an out-of-tolerance temperature or voltage condition exists. The system may not
continue operation. If a voltage measurement reaches this level, the power supply can shut down
the system. Immediate action is required.
The power supply monitors its own internal temperature and voltages. The power supply is either
within tolerance (normal) or out of tolerance (alarm level), as shown in Table 4. If an
internal-power-supply temperature or voltage reaches a critical level, the power supply shuts down
without any interaction with the processor.
Site Requirements
This section discusses the site environment requirements for the switch chassis.
AC and DC Power
The 376W, AC-input power supply contains an input autoranging circuit that allows it to operate on
input voltage and current within the ranges of 100 to 240 VAC and 47 to 63 Hz. It also features a
power factor correction (PFC) which keeps input circuits and harmonics low.
The 376W, DC-input power supply operates over the full DC range in both domestic and
international applications.
A second, identical power supply is also present in chassis configured with the redundant power
option. Redundant power ensures that power to the chassis continues uninterrupted in the event that
one power supply fails. It also provides uninterrupted power in the event that one power line fails;
the redundant power supply operates only if the power supplies are connected to separate input
lines. Table 1, “LightStream 1010 ATM Switch and Power Supply Specifications” lists system
power specifications, including input voltage and operating-frequency ranges.
Caution To avoid problems or damage to the switch, do not mix DC input power supplies with AC input power
supplies in individual switches.
The following warning applies to AC power supplies:
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase

Removing and Installing DC Power Supplies
Removing and Installing AC Power Supplies
The 376W power supplies (AC-input) that are used in the switch, support redundant hot swapping.
When two power supplies are installed, you can install, remove, or replace one of the supplies
without affecting system operation. When power is removed from one supply, the redundant power
feature causes the second supply to ramp up to full power and maintain uninterrupted system
operation. In systems with dual power supplies, connect each power supply to separate input lines
so that, in case of a line failure, the second source will most likely still be available and can maintain
maximum overcurrent protection for each power connection.
A modular power cord connects each AC power supply to the separate site power sources.
Warning Use both hands to remove and install power supplies. To see translated versions of this
warning, refer to the appendix “Translated Safety Warnings” in the LightStream 1010 ATM Switch
Hardware Installation Guide.
Note Each AC power supply weighs 11 pounds (4.98 kilograms).
Warning Keep hands and fingers out of the power supply bays. Voltage is present on the switch
backplane when the system is operating. To see translated versions of this warning, refer to the

without affecting system operation. When power is removed from one supply, the redundant power
feature causes the second supply to ramp up to full power and maintain uninterrupted system
operation. In systems with dual power supplies, connect each power supply to separate DC input
lines; in the event of a line failure, the second source is still available.
15
Removing and Installing Power Supplies
The DC input power supply is required by many telcos because their installations are equipped with
batty-backed DC power distribution. From an operational perspective, the DC input power supply
has the same characteristics as the AC input version.
The following caution applies to DC input power supplies:
Caution To be installed only in restricted access area (dedicated equipment rooms, equipment
closets, or the like) in accordance with articles 110-16, 110-17 and 110-18 of the National Electrical
Code, ANSI/NFPA 70.
Note The installation must comply with all applicable codes. In North America, installation must
comply with NEC (ANSI/NFPA 70) and CEC (OArt1, C22.1). Installation is approved for use with
copper connectors only. Attachment of the chassis ground M4 pamnuts to the central office or other
interior ground system should be made with a number 8 AWG copper ground connector as a
minimum. The chassis employs two threaded M4x.7 chassis ground M4 pamnuts. These pamnuts
are intended to be connected directly to the central office or other interior ground system, and are
located on the front of the chassis. The grounded chassis M4 pamnuts require M4 bolts and locking
hardware, which are not included.

Step 7
If the power supply bay is to remain empty, install a blank power-supply filler plate over
the opening and secure it with the mounting screws. This protects the inner chassis from
dust and prevents accidental contact with live voltage at the rear of the bay.
Replacing the DC Power Supply
Replace the DC power supply by following Step 1 through Step 4 in the section “Replacing the DC
Power Supply.”
Installing the DC Power Supply
Take the following steps to replace a DC power supply:
Caution To avoid problems or damage to the switch, do not mix DC input power supplies with AC
input power supplies in individual switches.
Step 1
Grasp the DC power-supply handle with one hand and place your other hand underneath
to support the bottom of the supply, as shown in Figure 12.
Step 2
Place the DC power supply into the power-supply bay and push the power supply into the
bay until the power supply faceplate is flush with the cover.
Step 3
Tighten each of the two captive installation screws by turning them clockwise.
Caution Turn screws simultaneously to avoid skewing the power supply.
Keep hands and fingers out of the power supply bays. Voltage is present on the switch
backplane when the system is operating. To see translated versions of this warning, refer to the
appendix “Translated Safety Warnings” in the LightStream 1010 ATM Switch Hardware Installation
Guide.

Step 4
Continue with the following section “Connecting DC Power.”
Connecting DC Power
Warning Before performing the procedure, ensure that all power is off to the DC circuit. Locate the
circuit breaker on the panel board that services the DC circuit and switch it to the off position. Tape
the circuit breaker switch handle in the off position to prevent accidental closing of the circuit. To
see translated versions of this warning, refer to the appendix “Translated Safety Warnings” in the
LightStream 1010 ATM Switch Hardware Installation Guide.
Follow these steps to connect the DC power supply to the DC voltage source:
Step 1
Verify that power is off to the DC input circuit.
Step 2
Ensure that the power switch is in the off (0) position on the power supply.
(See Figure 13.)
