The boot helper image resides in Flash memory on the I/O controller and contains a subset of the Cisco IOS software. This image is used to boot your router from the network or to load Cisco IOS images onto the router. This image is also used if the system cannot find a valid system image.
Your boot helper image should correspond to the Cisco IOS release that is running on your router. When you upgrade your Cisco IOS software to the minimum required software release (see Table 3-3, Table 3-4, and Table 3-5), we recommend that you also upgrade your boot helper image.
Also see the Cisco 7200 Series Routers Boot Images Information document for boot image information.
Note The Cisco 7200 boot image in Cisco IOS Release 12.0 and Cisco IOS Release 12.1 is oversized. If you need to upgrade the Cisco 7200 boot image, use the boot image in Cisco IOS Release 12.0S in place of the boot image in Cisco IOS Release 12.0 or Cisco IOS Release 12.1 releases. See the field notice Oversized Cisco 7200/uBR7200 BootImage document.
Make sure you upgrade the boot helper (boot loader) image on any previously purchased I/O controller before attempting to boot a Cisco 7200 VXR router or Cisco uBR7246VXR router that has a newly installed NPE-175, NPE-225, NPE-300, or NPE-400. When you install or upgrade the NPE-G1, NPE-G2, UBR7200-NPE-G1, or UBR7200-NPE-G2 you do not need to update the boot image because it is already installed on the processor at the factory.
To upgrade your boot helper image, obtain the most current boot helper image through Cisco.com and copy the new boot helper image to Flash memory on your router. For information on how to access Cisco.com, see the "Obtaining Documentation and Submitting a Service Request" section on page ix.
To obtain a boot helper image from Cisco.com and upgrade your bootflash, do the following:
Step 1 Download the boot helper image from Cisco.com to a TFTP server.
Step 2 Reformat the Flash memory on your router as follows:
router# format bootflash:
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "bootflash:". Continue? [confirm]
Formatting sector ...
Format of bootflash:complete
Note Reformatting Flash memory erases the current Flash memory contents.
Step 3 Copy the boot helper image from the TFTP server to Flash memory as follows:
router# copy tftp bootflash:
Address or name of remote host []? biff
Source filename []? c7200-boot-mz.120-5.S
Destination filename [c7200-boot-mz.120-5.S]?

Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
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.
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards or memory SIMMs or DIMMs are improperly handled and results in complete or intermittent failures.
The I/O controller and network processing engine or network services engine consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Hold the I/O controller and network processing engine or network services engine by their carrier edges and handle; never touch the printed circuit board or connector pins.
Figure 3-1 shows the location of a printed circuit board in a network processing engine or network services engine and an I/O controller metal carrier. Do not touch the printed circuit board when handling any of the components.
Figure 3-1 Handling the I/O Controller and the Network Processing Engine
or Network Services Engine
|
Printed circuit board |
|
Metal carrier |
Handle SIMMs or DIMMs by the edges only. Avoid touching the memory modules, pins, or traces—the metal fingers along the connector edge of the SIMM or DIMM. (See Figure 3-2.) Always wear a preventive antistatic wrist strap whenever you handle SIMMs or DIMMs.
Figure 3-2 Handling a SIMM or DIMM
Although the metal carrier helps to protect the I/O controller and the network processing engine or network services engine from ESD, wear a preventive antistatic strap whenever handling the I/O controller, network processing engine, or network services engine. Ensure that the strap makes good skin contact and connect the strap's clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Following are guidelines for preventing ESD damage:
•Always use an ESD wrist strap or ankle strap when installing or replacing the I/O controller, network processing engine or network services engine, Cisco uBR7200 series cable modem cards, or port adapters. Ensure that the ESD strap makes contact with your skin.
•Handle the I/O controller, network processing engine or network services engine, Cisco uBR7200 series cable modem cards, or port adapters by their metal carrier edges and handles; avoid touching the printed circuit board or any connector pins.
•When removing the I/O controller, network processing engine or network services engine, Cisco uBR7200 series cable modem cards, or port adapters, place them on an antistatic surface with the printed circuit board components facing upward, or in a static shielding bag. If you are returning an I/O controller, network processing engine, Cisco uBR7200 series cable modem card, or port adapter to the factory, immediately place it in a static shielding bag.
If your Cisco 7200 series router or Cisco uBR7200 series router is installed in a standard 19-inch, four-post rack or telco-type rack, cables from other equipment in the rack might obstruct access to the rear of the router. Also, rack power strips or other permanent fixtures may obstruct access to the router. Review the following guidelines to ensure easy access to the rear of the router when it is installed in a rack. If the router is not installed in a rack, or if you already have clear access to the rear of the router, proceed to Chapter 4, "Installing and Removing SDRAM and DRAM."
Use the following guidelines to ensure easy access to the rear of the router when it is installed in a rack:
•Ensure that you have at least 3 to 4 feet (0.9 to 1.3 meters) of working space at the rear of the router.
•If cables from other equipment in the rack fall in front of the rear end of the router, carefully gather the cables (using care not to strain them) and use cable ties to anchor them away from the rear of the router.
•If access to the rear of the router is partially blocked by a power strip or some other permanent rack fixture, detach the router from the rack and carefully slide it forward until there is enough clearance to remove the power supply, the network processing engine or network services engine, and the subchassis from the router. Detailed steps for detaching the router from the rack are contained in the "Removing the Network Processing Engine or Network Services Engine" section on page 4-8.
