Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
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 processor 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 megohms.
Required Tools
These tools are required to upgrade the memory module on the Cisco SAMI PPCs:
•Antistatic mat or antistatic foam
•Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares
Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.
The software is delivered as a bundle of images for the Cisco SAMI base card its components (for example, the line control processor [LCP] and daughter cards). The images are loaded onto the appropriate component automatically when the new software image is loaded. Each image in the bundle has its own version and release number that is used during the upgrade process to determine if an image needs to be installed.
To verify the software currently running on the Cisco SAMI supports the 2 GB memory upgrade option, refer to the Cisco mobile wireless application release notes. If the bundle does not support the memory upgrade, use the following procedure to upgrade the software.
For example, to upgrade the image bundle on a SAMI in slot 2 of a Cisco 7600 series router chassis, enter the following commands from the supervisor engine.
Sup> enableSup# upgrade hw-module slot 2 software tftp://10.1.1.1/c7svcsami-ipbase-mz.bouncer.070724Loading c7svcsami-ipbase-mz.bouncer.070724 from <TFTP SERVER IPADDRESS> (via Vlan10): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Slot Software File9 c7svcsami-ipbase-mz.bouncer.070724When an upgrade is initiated using the upgrade hw-module command, many processes occur automatically, including configuring the SAMI to automatically boot using the new image.
Note The Cisco SAMI will automatically boot from the new source file.
Upgrading the Cisco SAMI Memory
This section provides the procedures for removing and replacing the memory on the Cisco SAMI PPCs.
The synchronous dynamic RAM (SDRAM) on the Cisco SAMI PPC is contained in one dual inline memory module (DIMM). (See Figure 1.)
The Cisco SAMI has a default memory configuration of 1 GB, and is upgradable to 2 GB.
Caution To prevent ESD damage, handle the DIMM by the card edges only. (See Figure 3.) Place the removed DIMM on an antistatic mat or store it in an antistatic container.
Removing the PCC DIMM
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.
To remove the existing 1 GB DIMM, follow these steps:
Step 1 Make sure you take the necessary precautions to prevent ESD damage. (See the "Preventing Electrostatic Discharge Damage" section.)
Step 2 Remove the Cisco SAMI from the system. (Refer to the Cisco Service and Application Module for IP User Guide for removal instructions.)
Step 3 Place the Cisco SAMI on an antistatic mat or pad.
Step 4 Locate the DIMM. The six DIMMs are located side-by-side on the right side of the board. (See Figure 1.)
Figure 1 Cisco SAMI PPC DIMMs
Step 5 Pull the latches away from the DIMM at both ends and release the DIMM from the socket. (See Figure 2).
Figure 2 Releasing the DIMM Latches
Step 6 When both ends of the DIMM are released from the socket, grasp the ends of the DIMM with your thumb and forefinger and pull the DIMM completely out of the socket.
Handle the edges of the DIMM only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the DIMM), along the connector edge.
Step 7 Place the DIMM in an antistatic container to protect it from ESD damage.
Step 8 Repeat Step 5 through Step 7 to remove each of the six PPC DIMMs.
This completes the DIMM removal procedure. Proceed to the "Installing a New PPC DIMM" section to install the new DIMM.
Installing a New PPC DIMM
Caution DIMMs are sensitive components that are susceptible to ESD damage. Handle DIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the DIMM). (See Figure 3.)
Caution To prevent ESD damage, handle DIMMs as shown in Figure 3.
Figure 3 Handling a DIMM
Follow these steps to install the new DIMM:
Step 1 Make sure that both latches on the DIMM connector are open.
Step 2 Remove a new DIMM from the antistatic container.
The DIMM is designed in such a way that the connector will fit only one way.
Step 3 Hold the DIMM component side up, with the connector edge away from you. Line up the notch in the connector traces with the notch in the socket on the board.
Step 4 Carefully insert the connector edge into the socket and firmly press the DIMM into the socket until both latches rotate to the close position against the DIMM.
Caution When inserting DIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the Cisco SAMI to the factory for repair.
Note The space between the first DIMM and the module face plate is narrow. Therefore, the installation of the first DIMM is more difficult than the others. When installing the first DIMM, ensure that you carefully apply enough pressure to push the DIMM into place.
Step 5 Repeat Step 1 through Step 4 to install each of the DIMMs.
Step 6 Reinstall the Cisco SAMI in the system. (Refer to the Cisco Service and Application Module for IP User Guide for installation instructions.)
