Safety Information
When installing and operating the PSAX 1250 110 V ac Power Supply module,
follow the safety guidelines provided in the PacketStar®PSAX Multiservice Media
Gateway Safety Guidelines, which accompanies this product, to help prevent serious
personal injury and damage to the module. Please read all warnings and instruc-
tions supplied before beginning installation or configuration of the module. In
addition to the general safety information provided, you should also refer to the
PacketStar®PSAX 1250 Multiservice Media Gateway Installation Guide for other
important safety information and procedures.
Hardware Features Supported
The PSAX 1250 110 V ac Power Supply module only supports the 48.26-cm
(19-in.) PSAX 1250 chassis.
Description of the Module
Functional Description
The 110 V ac Power Supply module converts alternating current (AC) into direct
current (DC) and distributes power to the backplane and to all the modules in the
chassis. Each module includes status indicators and a power connector. When
using the 110 V ac Power Supply module, circuit protection must be supplied by
the customer.
In a redundant configuration, two Power Supply modules operate in a load-shar-
ing mode to increase system reliability. This configuration ensures that as long as
one Power Supply module is active, all other modules are fully powered. When
two Power Supply modules are installed, each normally runs at one-half of its
capacity. If one Power Supply module fails, the other module takes over
completely.
Note: A single AC Power Supply module may not fully power the chassis,
depending on which modules are being used. The total power con-
sumption of the modules installed in the chassis cannot exceed the
capacity of the AC Power Supply module. Refer to the appropriate
installation guide to identify the amount of power consumed by each
module and the AC Power Supply module.
Three LED indicators on the faceplate indicate the operational state of the
module.
Note: In order to use the AC Power Supply module, you must order a suit-
able AC power cordset for use in your geographic location. For your
convenience, Lucent Technologies has made a variety of international
cordsets available for ordering. See your Lucent Technologies account
manager for ordering details.

Module Placement
The PSAX 1250 110 V ac Power Supply module is installed in either slot 23 or 24
or both for redundant operation. The module can only be installed in the
48.26-cm (19-in.) PSAX 1250 chassis.
Installing the Module
Perform the following procedure to install the PSAX 1250 110 V ac Power Supply
module in the chassis.
Read the PacketStar®PSAX Multiservice Media Gateway Safety Guidelines, which
accompanies this product, before proceeding.
!DANGER:
Shock hazard! Do not perform any maintenance on this equipment until
you have turned off the power using the specified procedure. Failure to
observe proper precautions could cause serious injury or death.
Dangerous voltages are present in a PSAX 1250 110 V ac Power Supply mod-
ule when connected to an electrical power source. Connect the power cord-
set only after installing the module.
WARNING:
!
When inserting modules into the chassis, slide them gently, not forcefully.
Excessive force may cause the modules to be seated improperly in the chas-
sis, and result in possible damage to the module or the chassis. Install or
remove modules one at a time. Doing this aids in preventing the PSAX sys-
tem from indicating any erroneous failure messages, and allows the PSAX
system time to reinitialize and display the accurate configuration of the
module that is inserted.
Begin
Installing the Power Supply Module
1Remove the Power Supply module from its box and protective packing mate-
rial. Save these materials for future use, if needed.
2Loosen the captive screw in the ejector handle with a Phillips screwdriver
and pull the ejector handle out so that it hangs loose.
3Slide the Power Supply module into the top and bottom slot guides of either
slot 23 or 24 of the chassis.
4Position the ejector handle so the locking part fits over the locking rail.
5Firmly press against the top of the ejector handle to seat and lock the module
into place, as shown in Figure 3. Verify that the module is completely
inserted into the slot.

6Use a Phillips screwdriver to tighten the captive screw in the ejector handle
as shown in Figure 3.
7Plug the power cordset into the connection on the module.
8Plug the power cordset into the AC power source.
9Verify the indicators illuminate properly as described in the next section.

Verifying the Initial Startup
Once you apply power to the PSAX 1250 110 V ac Power Supply module, note
the status of the LED indicators as described in Table 3.

Table 3. Power Supply Module Status Indicators
Color Status Description
Red FAIL Indicates the module is not functioning properly or is not connected to a power
source in a redundant system.
If only one module is used in a PSAX 1250 system and the module fails, the indica-
tor is not illuminated and the entire chassis fails.
Green ACTIVE Indicates the module has power applied to it through the power cordset.
Yellow non-
redun-
dant
Indicates two different conditions depending on the number of modules in use:
•When only one module is installed, the indicator illuminates when the chassis
does not have a second operating module.
•When two modules are installed and operating properly, the indicator is not illu-
minated on either module. If one module fails or is removed from the chassis, the
indicator on the other working module illuminates. The indicator also illuminates
when at least one of the modules is drawing power at more than one-half of its
capacity, which is an abnormal condition. If one of the modules were to fail in
this situation, the other would not be able to fully power the system. If this situa-
tion occurs, contact Technical Support (see “Troubleshooting the Installation”).

Removing the Module
Perform the following procedure to remove the PSAX 1250 110 V ac Power Sup-
ply module from the chassis.
Read the PacketStar®PSAX Multiservice Media Gateway Safety Guidelines, which
accompanies this product, before proceeding.

DANGER:
Dangerous voltages are present in the PSAX 1250 110 V ac Power Supply
module when connected to a power source. Disconnect the power cordset
before removing the module.
WARNING:
!
Remove only one module at a time in a live network to prevent loss of data
or network failure.
!CAUTION:
When removing the Power Supply module from the chassis, avoid touching
the power supply heat sink because it will be hot.
Begin
Removing the Power Supply Module
1Unplug the power cordset from the AC power source.
2Unplug the power cordset from the Power Supply module.
3Using a Phillips screwdriver, loosen the captive screw in the ejector handle of
the Power Supply module as shown in Figure 4.
4Pull on the ejector handle until it releases the module from the backplane.
5Slide the module out of the chassis.
