However, if you use the display boot command to display the boot image it will only read from flash so only the primary image will be displayed. The secondary boot image name cannot be displayed when there is an image error. Upgrading Software Using Xmodem The Xmodem protocol transmits files through serial ports and supports both 128-byte and 1K-byte packets.
CHAPTER 4: MAINTAINING SOFTWARE 7 Change the baud rate set at the configuration terminal, so that the baud rate is consistent with the selected download baud rate of the software. 8 Disconnect the terminal and reconnect it. 9 Press Enter to start downloading. The terminal displays the following information: Now please start transfer file with XMODEM protocol. If you want to exit, Press . Waiting ... CCCCC 10 Select Transfer\Send File from the terminal window.
Lost Passwords Upgrading Software Using TFTP 55 TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used without complex interaction between clients and servers. The client initiates a TFTP transmission. To download files, the client sends a read request packet to the TFTP server, receives the packet from the server, and sends the acknowledgement to the server.

5 MAINTAINING HARDWARE This chapter covers the following topics: ■ Replacing a Power Module ■ Replacing a Power Supply ■ Replacing I/O Modules ■ Replacing the Fan Assembly The procedures in this chapter should be performed by trained service personnel only. Replacing a Power Module The single-cord power module in the 7- and 8-slot AC chassis of the Switch 7700 can be upgraded to a dual-power cord module.
CHAPTER 5: MAINTAINING HARDWARE 4 Tighten the retaining screw on the lower right front of the power supply. 5 Connect 2 power cords to the power module. 6 Connect the power cords to separate AC power sources on separate power grids or to a UPS/backup power system. WARNING: Do not power on the switch until you reconnect all the components.
Replacing I/O Modules 59 CAUTION: Do not clean the filter while it is in position at the front of the power supply. Attempts to do so could result in damage to the equipment or severe electrical shock. Replacing I/O Modules To replace an I/O module, you need: ■ An antistatic wrist strap ■ A Screwdriver To remove a module: 1 Remove all the cables from the module to be removed. 2 Loosen the captive screws.
CHAPTER 5: MAINTAINING HARDWARE 4 With both hands, pull out the ejector levers of the fan that will be installed. Align it with the guides in the chassis and slide it gently into the slot until you feel the positioning pin on the handle bar touch the hole in the chassis. 5 Press the ejector levers inward and seat the pin on the handle bar into the positioning hole in the chassis. WARNING: If the fan fails, replace it with a new one without delay before operating the Switch 7700.
6 TROUBLESHOOTING This chapter covers the following topics: ■ Troubleshooting the Configuration ■ Troubleshooting Power ■ Troubleshooting the Fan ■ Troubleshooting the Modules The simplest way to diagnose a fault is to check the system status LEDs on the Fabric modules. In addition, with the DeviceMgr network management system, you can also locate the fault through management software.
CHAPTER 6: TROUBLESHOOTING Table 37 describes power LEDs on the Fabric. (continued) Table 37 Power LEDs on the Fabric Troubleshooting the Fan LED Status Description OK On — The power is working normally. Off — The power has failed or has not been installed.
