CHAPTER 5
Field-replaceable Units
This chapter provides information to assist you with replacement of Field-replaceable Units (FRUs) at the Selenio™ Broadcast Network Processor (BNP) . The chassis does not need to be removed from the rack to replace a FRU, but the system must be powered down before beginning any replacement process.
If replaced items need to be configured, see the System Configuration chapter in your BNP User Guide.
Note: The BNP must be shut down/powered off prior to removal of the Network Processor Module, ASI
Module, or GBP3 Module. See “System Shutdown” on page 34 for more information.
It is not necessary to shut down nor power off the system when servicing hot-swappable modules.
Warning!
Never replace any FRU while the chassis is still connected to the power source.
See also “Power Source Safety Advisory” on page 48 for the localized version of the above warning.
Warning!
Do not replace any component (such as fuses) not specifically described here. For replacement beyond the FRU level, contact your technical support representative for
instructions on returning the component. See “Contacting Customer Support” on page 24 .
See also “FRU Replacement Advisory” on page 48 for the localized version of the above warning.
Warning: Whenever computer components are handled (especially during installation), the equipment can be damaged by the buildup of static electricity. Take precautions before touching any internal components or boards by wearing an ESD wrist strap or working on an antistatic mat. Always hold system modules by the edges and avoid touching any electronic circuitry on the cards.
Caution!
See also “Handling Computer Components” on page 44 and
“Electrostatic Advisory” on page 44 for the localized version of the above advisories.

Replacing a Power Supply
The power supplies are located at the rear of the BNP chassis. Any time that the chassis is not receiving adequate power, as indicated by the system LEDs and performance, verify that power is reaching the chassis.
If power is reaching the power supply but not getting to the system, you might need to replace one or both power supplies.
Note: The BNP operates normally with just one power supply.
Removing a Power Supply
The basic procedure for removing a power supply is similar regardless of whether the power supply is for AC or DC power.
To remove a failed power supply:
1.
Ensure that you have a replacement power supply ready to reinsert.
2.
Ensure that there is no power to the unit:
• AC power supply units - Shut down the unit by removing the power cable from the power supply connector.
• DC power supply units - Toggle the circuit breaker to the OFF position. Disconnect the cables from the power connector.
3.
Loosen the power supply unit by turning the safety screw clockwise.
Note: Turning the screw counterclockwise tightens the screw. Use a slotted screwdriver to tighten or loosen the screw, then use your fingers to further turn the screw, if necessary.
4.
Firmly grasp the power supply by the handle, shown in Figure 15 (AC Power Supply) and Figure 16
(DC Power Supply).

Inserting a Power Supply
Once you have removed the failed power supply, install a replacement:
1.
Remove the replacement power supply from its packing and carefully inspect it for damage.
Do not install a visibly damaged power supply.
2.
Slide the replacement power supply into the slot

3.
Turn the screw counterclockwise to tighten it, securing the power supply to the BNP chassis.
4.
Connect power to the power supply:
•
For AC power supplies, refer to “Connecting AC Power to the BNP” on page 18
.
• For DC power supplies, refer to
“Connecting DC Power to the BNP” on page 19 .

Removing a GBP3 Module
Removing a GBP3 Module
1.
Ensure that you have a replacement module available, then shut down the unit by removing the power cable from the power supply connector.
2.
Remove all cabling from the module.
3.
Grasping it firmly with your fingers, gently remove the bezel on the front of the chassis (
Figure 19
).

4.
Using a Phillips screwdriver, loosen—but do not remove—the screws that secure both sides of the
GBP3 module to the chassis. They act as handles to assist with the module’s removal.

Replacing a Processor Module (PROC3) or an ASI Module
Replacing a GBP3 Module
After you have removed the failed GBP3 module, replace it with the new one:
1.
Grasp the module firmly by the edges only and slide it into the chassis, using the plastic guide rails to ensure proper seating.
2.
Push until the module is firmly seated.
3.
Using a Phillips screwdriver, tighten the insertion/removal screws to secure the GBP3 module to the
BNP chassis.
4.
Replace the front bezel by snapping it in place.
5.
Restore any cabling and power up the unit.
Replacing a Processor Module (PROC3) or an ASI
Module
Note: The BNP supports both ASI and ASI2 modules.
Removing and replacing either a PROC3 module or an ASI module uses the same procedure.
• If you are adding a new PROC3 or ASI module to an existing but underpopulated chassis, insert the card into the next designated slot.
• If you are replacing a failed unit, simply replace that unit regardless of the slot it occupies.
Removing a PROC3 or ASI Module
1.
Use the Element Manager to perform the following tasks:
Delete all input and output groomings associated with the ASI module to be removed.
Delete all output programs and output TSs associated with the ASI module to be removed.
2.
Shut down the unit by removing the power cable from the power supply connector.
3.
Using a Phillips screwdriver, loosen—but do not remove—the insertion/removal screws, shown in
Figure 22
.

Using the handles on either side of the module as a grip, gently but firmly slide the module out of the chassis, as shown in
Figure 23 .

Replacing a PROC3 or ASI Module
After a PROC3 module has been removed, replace it as soon as possible, or install a blank slot cover to ensure proper air flow. If you are leaving an empty slot, any empty slot should be fitted with a blank cover.
Caution: ASI modules should always be replaced; no filler should be used.
See also “ASI Module Replacement Advisory” on page 49 for the localized version of the above caution.
To install a PROC3 or ASI module:
1.
Firmly hold the card by the edges or the handles and slide it into the chassis, using the plastic guide rails to ensure proper seating.
2.
Press firmly until the module seats in the chassis.
