This recovery diskette is for use with the Cisco Cache Engine. You only need to use this diskette if your system disk is corrupted and you cannot boot the Cache Engine. Your system disk might become corrupted if power goes out while you are upgrading the system software.
This diskette only allows you to boot the machine to a point where you can recover the system software from a server on your network. The diskette does not contain the system software.
To boot the Cache Engine from the recovery diskette:
Step 1 Remove the diskette drive cover from the front of the Cache Engine (as shown in Figure 1) by unscrewing it and insert the recovery diskette supplied with the engine.
Step 2 In order of preference, do one of the following:
(a) Enter the reboot command at the Cache Engine's console.
(b) Push the reset button on the front of the Cache Engine. This is a recessed button on the lower left side of the front panel. You must use a pointed device (such as a pen tip) to press the button.
(c) Turn the machine off, then turn it back on.
Step 3 Once the Cache Engine finishes rebooting, you can connect to the engine using FTP to copy a new image onto the engine, as described in "Upgrading the System Software." If the disk that contains the system software is damaged, call Technical Support for help.
If you need to recover the system software, or replace it with an upgrade, you can obtain the software from Cisco Connection Online or by ordering the upgrade media. When you have the software, to recover the system software, or upgrade a Cache Engine:
Step 1 Put the upgrade software on your Windows NT or UNIX machine. The upgrade software is one file.
Step 2 From the Windows NT or UNIX machine, FTP to the Cache Engine and log in using an existing Cache Engine account with read-write authority (for example, the admin account). For example, to FTP to the Cache Engine 192.168.88.89:
ftp 192.168.88.89
You are placed in the correct directory, which is /ata0/. If you are not in this directory, use the cd command to change directories, putting the directory name in quotes:
cd "/ata0/"
Step 3 Change to binary mode:
bin
Step 4 Put the file to the Cache Engine. For example, if the upgrade software's file name is Ver-2.pax, enter:
put Ver-2.pax
You can now quit the FTP session.
Step 5 From the Cache Engine's console, enter the Pax command to unpack the file. For example, if the file name is CE2050_1.1_1, enter:
Pax "CE2050_1.1_1", "-x"
Replace CE2050_1.1_1 with the name of the file that you put onto the engine. You must enter all other characters as shown. When you press the Enter key, the engine starts extracting the files that comprise the system software.
This file extraction preserves your current configuration, including URL and MIME blocking lists. The Pax command creates a subdirectory for the new software version based on the version numbers for the software. Previous versions of the software remain on the engine.
Step 6 From the Cache Engine's console, reboot the engine:
reboot
