Replacing a GRP Step 7 Place the removed GRP on an antistatic mat or foam. If you plan to return the GRP to the factory, immediately place it in an antistatic bag to prevent ESD damage. Installing a GRP When you install a GRP, be sure to use the ejector levers, which help to ensure that the GRP is fully inserted in the backplane connector. (See Figure 3.
Replacing a GRP Connecting to the Console Port The system console port on the GRP is a DCE DB-25 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 5. Before connecting the console port, check your terminal’s documentation to determine the baud rate of the terminal you plan to use. The baud rate of the terminal must match the default baud rate (9600 baud).
Replacing a GRP Connecting to the Auxiliary Port The auxiliary port on the GRP is an EIA/TIA-232 DTE, DB-25 plug for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The port is labeled Auxiliary. An example of a modem connection is shown in Figure 5. The asynchronous auxiliary port supports hardware flow control and modem control. Table 3 lists the pinout for this port.
Replacing a GRP RJ-45 Receptacle and Plug (Horizontal Orientation) 87654321 RJ-45 receptacle Warning Category 5, UTP cable with plug H11096 Figure 6 The ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the basic rate interface (BRI) circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.
Replacing a GRP MII Connections The MII connection requires an external physical sublayer (PHY) and an external transceiver. Depending on the type of media you use between the MII connection on the GRP and your switch or hub, the network side of your 100BASE-T transceiver should be appropriately equipped—with SC-type or ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 9 shows the pin orientation of the female MII receptacle on GRP.
Replacing a GRP Table 6 lists the cabling specifications for 100-Mbps transmission over unshielded twisted-pair (UTP) and shielded twisted-pair (STP) cables. Note At the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth that is less than 100 Mbps; a maximum usable bandwidth of approximately 20 Mbps can be expected if you use either the MII or RJ-45 connection.
Replacing a GRP • MII connections—Attach an MII cable directly to the MII receptacle on the GRP or attach a 100BASET transceiver with the media appropriate to your application to the MII port on the GRP. (See Figure 10.) Be sure to use the appropriate strain relief on cable connections. • RJ-45 connections—Attach the Category 5 UTP cable directly to the RJ-45 receptacle on the GRP. (See Figure 10.
GRP Boot Process Overview Figure 11 Using the Ethernet Port on the GRP Network 1.0.0.0 Router A (Cisco 12000 series) Host A EO POS Host B Network 2.0.0.0 EO Router B (Cisco 7500 series) Router C (Cisco 7500 series) S6755 Host A GRP Boot Process Overview The following sequence describes a typical GRP boot process: 1. System power is turned on. 2. MBus module receives +5 VDC and starts executing MBus software. 3.
Starting the System and Observing Initial Conditions For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the green input OK LED should go on. For both types of power supplies, the output fail LED should be off. Step 2 Listen for the system blower modules or fan trays in the router; you should immediately hear them operating. In a noisy environment, place your hand in front of the exhaust vents to verify that the blower modules are operating.
Starting the System and Observing Initial Conditions Step 4 During the line card boot process, which occurs immediately after the GRP boots, observe the alphanumeric display LEDs on each line card. The system attempts to boot identical line cards in parallel. Furthermore, the system boots line cards as soon as they are powered on and become available for a system boot. (The physical location of the alphanumeric display LEDs on the line cards is the same as on the GRP, which is shown in Figure 12.
Verifying Interface Status On the console screen, after the system displays the system banner and hardware configuration, the following System Configuration Dialog prompt appears: --- System Configuration Dialog --At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'.

Implementing Additional Configuration and Maintenance Tasks Caution The Flash memory card or Flash disk does not insert all the way inside the GRP; a portion of the card remains outside of the slot. Do not attempt to force the card past this point. Use the following procedure to remove a Flash memory card or Flash disk: Step 1 To eject the card, press the ejector button until the card is free of the connector at the back of the slot. (See Figure 14c.
Implementing Additional Configuration and Maintenance Tasks Caution The following formatting procedure erases all information on the Flash memory card or Flash disk. To prevent the loss of important data that might be stored on a Flash memory card or Flash disk, proceed carefully. If you want to save the data on a Flash memory card or Flash disk, copy the data to a server before you format the card.
Implementing Additional Configuration and Maintenance Tasks Specifying Cisco IOS Image Used to Boot the System Use the following series of commands to specify that a Cisco IOS software image is bootable. (In this example, the file is named new.image.) Note that because the configuration register must be set to 0x2102, the config-register command is part of the sequence. Router# config terminal Router(config)# no boot system Router(config)# boot system flash slot0:new.
Implementing Additional Configuration and Maintenance Tasks You can delete a file from any Flash memory media using the delete filename command, where filename is any file within Flash memory.
Implementing Additional Configuration and Maintenance Tasks Enter configuration commands, one per line. End with CTRL-Z. Router(config)#config-reg 0x2102 Router(config)#boot system disk0:gsr-p-mz.120-17.S Router(config)#^Z Router#copy running-config startup-config Copying Files to Flash Memory Copying a new Cisco IOS software image to Flash memory might be required whenever a new Cisco IOS software release or maintenance release becomes available.
Implementing Additional Configuration and Maintenance Tasks Copying a Cisco IOS Software Image into Flash Memory Card or Flash Disk You can copy a Cisco IOS software image into Flash memory; however, you must first format the Flash memory card or Flash disk and make the image in the Flash memory card or Flash disk bootable.
Implementing Additional Configuration and Maintenance Tasks Copying Cisco IOS Software Images Between Flash Memory Cards or Flash Disks As future releases of Cisco IOS software become available, you will receive these images either as a file booted from a network server, a file on floppy disk, or a file on a Flash memory card or Flash disk.
Implementing Additional Configuration and Maintenance Tasks Step 5 Use the following series of commands to designate the file image.new (in the Flash memory card or Flash disk in slot 0) as the default boot image: Router# config t Router(config)# no boot system Router(config)# boot system flash slot0:image.new Crtl-z Router# copy running-config startup-config Router# reload When the system reloads, it will boot the file image.new from the Flash memory card or Flash disk in slot 0.
Implementing Additional Configuration and Maintenance Tasks Step 2 Enter the copy startup-config slot0:filename command as follows: Router# copy startup-config slot0:myfile2 20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [1.1.1.1]? Loading new.image from 1.1.1.
Implementing Additional Configuration and Maintenance Tasks Step 1 Use the copy running-config slot0:filename command as follows: Router# copy running-config slot0:myfile2 20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [1.1.1.1]? Loading new.image from 1.1.1.
Implementing Additional Configuration and Maintenance Tasks Recovering from Locked Blocks in Flash Memory Cards or Flash Disks A locked block in Flash memory cards or Flash disks occurs when power is lost, or a Flash memory card or Flash disk is unplugged during a write or erase operation. When a block of Flash memory is locked, it cannot be written to or erased, and the operation will consistently fail at a particular block location.
Implementing Additional Configuration and Maintenance Tasks Step 6 Set the configuration register to ignore the configuration file information as follows: rommon 1> confreg Configuration Summary enabled are: console baud: 9600 boot: image specified by the boot system command or default to: cisco2-GRP do you enable enable enable enable enable enable change change wish to change the configuration? y/n [n]: y “diagnostic mode”? y/n [n]: “use net in IP bcast address”? y/n [n]: “load rom after netbootfails”?
Implementing Additional Configuration and Maintenance Tasks Change it to a value of 0x2102 (factory default) using the config-register 0x value command. Step 13 Enter Ctrl-Z to exit configuration mode. Step 14 Reboot the router and enable it using the recovered password. Upgrading GRP Memory This section provides the procedure for increasing the amount of extended data output (EDO) DRAM on a GRP by replacing up to two dual in-line memory modules (DIMMs).
Implementing Additional Configuration and Maintenance Tasks Note Each GRP DIMM socket has one plastic lever on one end, which you use to remove the DIMM from its socket. (See Figure 16.) Before proceeding, ensure that you have the proper tools and ESD-prevention equipment available. To upgrade DRAM, you will install DIMMs in one or two banks (U39 and U42). Table 14 lists the various available configurations of DRAM DIMMs, the number of DIMMs for each configuration, and the DRAM banks they occupy.
Implementing Additional Configuration and Maintenance Tasks Removing DIMMs This section provides the procedure for removing DIMMs. As you remove DIMMs, place them on an antistatic mat or store them in an antistatic bag. You can use the DIMMs that you remove in other compatible equipment. Caution To prevent ESD damage, handle DIMMs by the card edges only. Use the following procedure to remove the existing DIMM(s): Step 1 Turn off the system power.
Implementing Additional Configuration and Maintenance Tasks Installing New DIMMs This section provides the procedure for installing new DIMMs. Caution To prevent system and memory problems when installing DRAM, make sure that the card’s DRAM DIMMS are +3.3VDC, 60-ns, EDO devices. Do not attempt to install other DRAM devices in the GRPs DIMM sockets. Caution DIMMs are sensitive components that can be shorted by mishandling; they are susceptible to ESD damage.
Obtaining Documentation Step 8 Caution Step 9 When the DIMM is installed, check that the release lever is flush against the side of the DIMM socket. If it is not, the DIMM might not be seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until the release lever is flush against the side of the DIMM socket. When inserting DIMMs, use firm but not excessive pressure.
