Safety
Warning
Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.
Warning
The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.
Warning
Class 1 laser product.
Warning
Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processing modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
Connect the equipment end of the strap to an unfinished chassis surface.
•
When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
•
When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
•
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
•
Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
•
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•
Never attempt to remove the printed circuit board from the metal carrier.
Caution 
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
Supported Hardware
The Cisco SCE8000 platform supports the following hardware:
•
One Service Control Module (SCE8000-SCM-E), with an optional redundant Service Control Module (FRU).
•
One SPA jacket module (SCE8000-SIP), with either two or four SPA 10GBE interface modules (all FRU).
•
Up to two optical bypass modules installed in the bottom slot of the chassis.
•
Hot-swappable fan assembly, redundant AC-input or DC-input power supplies.

Figure 9-2 Handling the AC Power Supply
Installing an AC-Input Power Supply
Warning
This product requires short-circuit (over current) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.
Step 1
Ensure that the system (earth) ground connection has been made. For ground connection instructions, see Connecting the System Ground, page 4-20
Step 2
Verify that the power switch is in the Off (0) position.
Step 3
Grasp both power supply handles, as shown in Figure 9-2. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.
Step 4
Securely tighten the power supply captive installation screws. (See Figure 9-1.)
Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Step 5
Plug the power cord into the power supply.
Step 6
Connect the other end of the power cord to an AC-input power source.
Caution 
In a system with dual power supplies, connect each power supply to a separate input source. In case of a power source failure, the second source will most likely still be available.
Step 7
Turn the switch on the power supply to the On (|) position.
Step 8
Verify power supply operation by checking the power supply LEDs.
The power supply LEDs should be in the following states:
•
INPUT OK LED is green
•
FAN OK LED is green
•
OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see Identifying Startup Problems, page 8-7 for troubleshooting information.
Removing a DC-Input Power Supply
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Warning
Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands and fingers out of the power supply bays and backplane areas.
Step 1
Verify that power is off to the DC circuit connected to the DC-input power supply you are removing.
Step 2
Remove the four screws securing the terminal block cover, and slide the cover off the terminal block.
Figure 9-3 DC-Input Front Panel for 2700-W DC-Input Power Supply
Step 3
Remove the two screws securing each of the cable holder covers, and remove the cable holder covers off the cable holders.
Step 4
Disconnect the DC-input wires from the terminal block.
Always disconnect the DC-input wires in this order:
•
Positive (+)
•
Negative (-)
•
Ground
Warning
When installing the unit, the ground connection must always be made first and disconnected last.
Step 5
Remove the two tie-wraps from the ground cable. If there is a long cable tie securing the cable holders, remove that as well.
Step 6
Loosen the captive installation screws on the power supply (Figure 9-3).
Caution 
Use both hands to install and remove power supplies. Each PWR-2700-DC DC/4-input power supply weighs 19.8 pounds (9.0 kg).
Step 7
Grasp both power supply handles, as shown in Figure 9-4, and slide the power supply completely out of the chassis.
Figure 9-4 Handling a DC-Input Power Supply
Installing a DC-Input Power Supply
This section covers the DC-input power supply installation procedure for the Cisco SCE8000 chassis.
Note
The DC return is to remain isolated from the system frame and chassis (DC-I).
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Step 1
Power supply ground is required. Install the PWR-2700-DC/4 power supply ground as described in this procedure.
Note
The system ground connection with the PWR-2700-DC/4 power supply in a Cisco SCE8000 is provided by the PWR-2700-DC/4 power supply ground. Additionally, you can connect a system (earth) ground.
Caution 
You must always connect the PWR-2700-DC/4 power supply ground.
Caution 
You must connect the PWR-2700-DC/4 power supply ground for both power supplies.
Note
If you intend to use an additional system (earth ground), ensure that the system ground connection has been made. For ground connection installation instructions, see Connecting the System Ground, page 4-20.
Step 2
Remove the plastic bag attached to the front panel and put aside. This bag contains two plastic terminal block barriers, two cable ties, and two cable holder covers.
Step 3
Verify that power is off to the DC circuit connected to the power supply you are installing. Grasp both power supply handles, as shown in Figure 9-4. Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.
Step 4
Tighten the power supply captive installation screws.
Warning
Power supply captive installation screws must be tight to ensure protective grounding continuity.
Note
As the power requirement of the SCE8000 will not exceed 1350W, it is not necessary to connect two pairs of input wires to each power supply. Should it be desired to connect two pairs of input wires, both pairs of input wires for one 2700W DC-input power supply must come from the same battery system (A feed); and both pairs of input wires for the other power supply must come from another battery system (B feed).
Note
For multiple DC input power supply, each DC input must be protected by dedicated circuit breaker or fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local or national electrical code requirements.
Step 5
Remove the four screws securing the terminal block cover, and slide the cover off of the terminal block (Figure 9-5).

Step 6
Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according to local and national installation requirements. Use only copper wire. The maximum width of a lug is 0.600 inch (15.2 mm).
Note
Use fine-stranded copper conductors rated for 90-degrees Celsius for North American installations.
Note
The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you use an appropriately sized industry standard 2-hole, standard barrel compression lug. The power supply ground studs, located below the terminal block, are also threaded 1/4-20 and require two 1/4-inch split-ring washers and two 1/4-20 hex nuts.
Step 7
Connect the DC-input wires to the 2700 W power supply terminal block . Depending on which side you are connecting the DC-input wires, be sure that the DC-input wires rest in the appropriate cable holder. Figure 9-6 shows DC-input wires coming in from the left side.
Connect the DC-input wires to the 2700 W power supply terminal block in this order:
•
Ground
•
Negative (-)
•
Positive (+)
Note
When you tighten the terminal nuts, make sure they are snug. Do not over tighten them. Recommended torque strength is 20 inch-pounds. Over tightening the terminal nuts can break the terminal block (Maximum torque: 36 inch-pounds).
Figure 9-6 DC-Input Wires on Left Side
When installing the unit, the ground connection must always be made first and disconnected last.
Step 8
Secure the ground cable to the cable holder with the two cable-ties.
Step 9
Retrieve the cable holder covers from the plastic bag and attach to the front panel at the locations shown in Figure 9-3.
Note
If the cable holder illustrated as number 5 and 8 in Figure 9-3 does not hold the DC input cables snugly, please use a long cable tie to secure the cable holders as illustrated in number 9.
Step 10
Secure the terminal block cover using four screws and the terminal block barriers with two screws each.
Step 11
Turn on the DC inputs and verify power supply operation by checking the power supply front panel LEDs.
The power supply rear panel LEDs should be in the following states:
•
INPUT OK LED is green
•
FAN OK LED is green
•
OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see Identifying Startup Problems, page 8-7
Removing and Replacing the Fan Assembly
This section describes how to remove and replace fan assemblies for the Cisco SCE8000 chassis.
•
Required Tools
•
Removing the Fan Assembly
•
Installing the Fan Assembly
Required Tools
A flat-blade or number 2 Phillips-head screwdriver is required to perform this procedure.
Removing the Fan Assembly
The fan assembly is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.
Step 1
Loosen the two captive installation screws by turning them counterclockwise.
Figure 9-7 Fan Assembly
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray.
Step 2
Grasp the fan assembly with both hands and pull it outward; rock it gently if necessary to unseat the power connector from the backplane (Figure 9-7).
Step 3
Pull the fan assembly clear of the chassis, and put it in a safe place.
Installing the Fan Assembly
Step 1
Hold the fan assembly with the fans facing to the right and the FAN STATUS LED at the bottom. (See Figure 9-7.)
Step 2
Place the fan assembly into the front chassis cavity so that it rests on the chassis, and then lift the fan assembly up slightly, aligning the top and bottom chassis guides.
Step 3
Push the fan assembly into the chassis until the power connector seats in the backplane and the captive installation screws make contact with the chassis.
Step 4
Tighten the captive installation screws.
Step 5
Verify that fans are operational.
•
Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan assembly is inserted completely in the chassis and the faceplate is flush with the switch back panel.
•
Verify that the FAN STATUS LED is green. If the LED is red, one or more fans is faulty.
Removing and Replacing Modules
The Cisco SCE8000 platform supports two types of modules:
•
Service Control Module (SCE8000-SCM-E)
•
SPA Interface Processor (SCE8000-SIP)
Figure 9-8 shows the position of these modules in the Cisco SCE8000 chassis.
Figure 9-8 Slot Numbers on Cisco SCE8000 Chassis
Required Tools
These tools are required to remove or install modules in the Cisco SCE8000 chassis:
•
3/16-inch flat-blade screwdriver
•
Number 2 Phillips screwdriver
•
Wrist strap or other grounding device
•
Antistatic container that the module was shipped in
Handling SIPs
Each SIP circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.
Always handle the SIP by the carrier edges and handle; never touch the SIP components or connector pins. (See Figure 9-9.)
When a slot is not in use, a blank filler plate must be installed in the empty slot to allow the SCE platform to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a SIP in a slot that is not in use, you must first remove the blank filler plate.
Figure 9-9 Handling a SIP
Installing a Module
Step 1
Choose a slot for the module.
Modules must be installed in the proper slots, as follows:
•
A single SCE8000-SCM-E module must be installed in slot #1.
•
If a second SCE8000-SCM-E module is used, it must be installed in slot #2.
•
The SCE8000-SIP module must be installed in slot #3.
Step 2
At the SCE# prompt, type reload shutdown and press Enter to power down the Cisco SCE8000 platform before installing or removing any module.
Step 3
Make sure that there is enough clearance to accommodate any interface equipment that you will connect directly to the module ports.
Step 4
Verify that the captive installation screws are tightened on all modules already installed in the chassis to ensure that the EMI gaskets on all modules are fully compressed in order to maximize the opening space for the new or replacement module.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, reducing the opening size and making it difficult to install the replacement module.
Step 5
Remove the module filler plate by removing the two Phillips pan-head screws from the filler plate. To remove a module, follow the procedure in Removing a Module
Step 6
Fully open both ejector levers on the new module. (See Figure 9-10.)
Figure 9-10 Ejector Levers and Captive Installation Screws
Step 7
Position the module in the slot. (See Figure 9-11.) Make sure that you align the sides of the module carrier with the slot guides on each side of the slot.
Figure 9-11 Positioning the Module in the Slot
Step 8
Carefully slide the module into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have closed to approximately 45 degrees with respect to the module faceplate. (See Figure 9-12.)
Figure 9-12 Clearing the EMI Gasket
Step 9
Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small (0.040 inch [1 mm]) gap between the module EMI gasket and the module above it. (See Figure 9-12.)
Caution 
Do not press down too forcefully on the ejector levers. They will bend and be damaged.
Step 10
While pressing down, simultaneously close the left and right ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 9-13)
Note
Failure to fully seat the module in the backplane connector can result in incorrect operation and/or error messages.
Figure 9-13 Ejector Lever Closure
Step 11
Tighten the two captive installation screws on the module.
Note
Make sure the ejector levers are fully closed before tightening the captive installation screws.
Removing a Module
Before you remove an SCE8000-SCM, you should first save the current configuration, if the current configuration should be preserved and duplicated on the new SCE8000-SCM-E. (Use the copy running-config startup-config command.) This step saves time when bringing the module back online, if the configuration will remain the same or similar. You can recover the configuration by downloading it from the server to the nonvolatile memory of the SCE8000-SCM-E.
Tip
When you install a new SCE8000-SCM-E, check the factory default configuration; you might need to reconfigure the system to your requirements. You can reconfigure the SCE8000-SCM-E manually, or if you previously uploaded the original configuration to a server, you can download it to the new SCE8000-SCM-E.
Step 1
At the SCE# prompt, type reload shutdown and press Enter to power down the Cisco SCE8000 platform before installing or removing any module.
Step 2
Verify that the captive installation screws on all of the modules in the chassis are tight. This step assures that the space created by the removed module is maintained.
Note
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, reducing the opening size and making it difficult to install the replacement module.
Step 3
Disconnect all cables.
Step 4
Loosen the two captive screws on the module.
Step 5
Place your thumbs on the left and right ejector levers and simultaneously rotate the levers outward to unseat the module from the backplane connector.
Step 6
Grasp the front edge of the module and slide the module part of the way out of the slot.
Step 7
Pull the module out of the slot. Place your other hand under the module to support the weight of the module. Do not touch the module circuitry.
Step 8
Place the module on antistatic foam, or immediately reinstall it in another slot.
Step 9
If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain proper airflow through the chassis.

Required Tools and Equipment
You need the following tools and parts to install SPAs. If you need additional equipment, contact a service representative for ordering information.
•
Shared port adapter (SPA)
•
Number 1 Phillips and a 3/16-inch flat-blade screwdriver
•
Number 2 Phillips screwdriver
•
Your own electrostatic discharge (ESD)-prevention equipment or the disposable grounding wrist strap supplied with the SPA
•
Antistatic container that the SPA was shipped in
Laser/LED Safety
An optical single-mode transmitter uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it. Although multi-mode transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and avoid staring into open ports or apertures. The transceivers aperture port contains a laser warning label, as shown in Figure 9-15. These warnings apply to SPAs and XFP modules that transmit signals via an optical carrier signal.
Figure 9-15 Class 1 Laser Warning Labels for SPA Ports
Warning
Class 1 laser product. Statement 1008
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Warning
Class 1 LED product. Statement 1027
Handling SPAs
Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.
Always handle the SPA by the carrier edges and handle; never touch the SPA components or connector pins. (See Figure 9-16.)
When a subslot is not in use, a SPA blank filler plate must fill the empty subslot to allow the chassis to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a SPA in a subslot that is not in use, you must first remove the SPA blank filler plate.
Figure 9-16 Handling a SPA
SPA Installation and Removal
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
SPAs can be inserted or removed independently from the SIP. Removal of a SIP with installed SPAs is also supported.

Installing a SPA in a SIP
To install a SPA in a SIP, refer to Figure 9-17 and do the following:
Step 1
At the SCE# prompt, type reload shutdown and press Enter to power down the Cisco SCE8000 platform before installing or removing any module.
Step 2
To insert the SPA in the SIP, locate the guide rails inside the SIP that hold the SPA in place. They are at the top left and top right of the SPA slot and are recessed about an inch, as shown in Figure 9-17.
Step 3
Carefully slide the SPA all the way in the SIP until the SPA is firmly seated in the SPA interface connector. When fully seated, the SPA might be slightly behind the SIP faceplate.
Step 4
After the SPA is properly seated, fasten the SPA in place with the captive installation screws.
Removing a SPA from a SIP

Replacing the Optical Bypass Module without Disrupting Traffic on the Link
Removing the Optical Bypass Module
Step 1
Disconnect all cables.
Step 2
Loosen the two captive screws on the module.
Step 3
Pull the module out of the slot. Place your other hand under the module to support the weight of the module. Do not touch the module circuitry.
Step 4
Place the module on antistatic foam, or immediately reinstall it in another slot.
Step 5
If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain proper airflow through the chassis.
Installing the Optical Bypass Module
Step 1
Remove the module filler plate by loosening the two screws.
Step 2
Insert the module into the opening in the panel. There are no guide rails. Do not touch the module circuitry.
Step 3
Tighten the two captive screws on the module.
Step 4
Connect the cables as described in Cabling the 10GBE Line Interface Ports: Using the External Optical Bypass Module, page 6-13.
Replacing the Optical Bypass Module without Disrupting Traffic on the Link
You can replace a malfunctioning SCE8000 platform without disrupting traffic on the link by removing the optical bypass modules while still connected to the network and installing them into the new SCE8000.
Step 1
Install the new SCE8000 platform in the rack. Power up the platform and perform necessary initial configuration.
Step 2
Disconnect the cables connecting the optical bypass module to the old SCE8000 platform. Do not disconnect the cables connecting the optical bypass to the subscriber side or network side network elements.
Step 3
Remove the optical bypass module from the SCE8000 chassis and immediately install it in the new SCE8000 platform. Alternatively, it can be installed in an external mounting panel elsewhere in the rack.
Step 4
Connect the cables from the optical bypass module to the line interfaces of the new SCE8000 platform. See Optical Bypass Module Connectivity, page 6-9.
