Specifying a Network-Mounted File System as the Primary Boot Record
Set Network as the primary boot record when you want to boot the CSS from a network-mounted file system on a remote system using FTP. Instead of the CSS disk, the network file system contains the CSS software. The CSS boots from this file system and loads the configuration into memory.
Perform a network boot when:

Specifying FTP as the Primary Boot Record
Select FTP as the primary boot record when you want to upgrade the CSS software on the CSS disk. The CSS accesses the ADI or GZIP file containing the CSS software from an FTP server, copies it to the disk, and unpacks the software. Then the CSS boots from disk (hard or Flash disk).
Make sure that you properly connect the Ethernet management port on the CSS to the network. Note the locations of the Ethernet management port on the CSS as listed below.

Setting IP Address, Subnet Mask, and Default Gateway
When you select Set IP Address and Subnet Mask from the Boot Configuration menu, the CSS prompts you to:
1.
An IP address of 0.0.0.0 for the Ethernet management port is a legal setting and disables the management port upon reboot. If you enter 0.0.0.0, and you attempt to use the subnet mask command, the following message appears: The mask cannot be set because the IP address is 0.0.0.0. To enable the Ethernet management port, use the Boot Configuration menu to enter an IP address for the management port.
The Ethernet management port IP address must be a different subnet than any other CSS VLAN circuit IP subnet. If you do not make the Ethernet management port IP address unique, you cannot access the port.
Enter IP Address or 0.0.0.0 to disable [<current value>]: 10.3.6.582.
Enter Subnet Mask: 255.0.0.03.
Enter Default Gateway: 172.16.11.14.

Using the Advanced Options
The CSS hard disk or Flash disk enables you to store two versions of software (including the version you are currently running). If you are storing the maximum number of software versions on the CSS and wish to download a new version to the disk, you must delete a version before the CSS allows the download to begin.
When you select Advanced Options from the Offline DM Main menu, the CSS displays the Advanced Options menu:
A D V A N C E D O P T I O N SEnter the number of a menu selection:1. Delete a Software Version2* Security Options3* Disk Options4. Set MSD Mappingr. Return to previous menuDeleting a Software Version
To delete a software version from the disk:

Changing the Administrative Username and Password
During the initial log in to the CSS, you enter the default user name admin and the default password system as lowercase text. For security reasons, you should change the administrative username and password through the Security Options menu. Security on your CSS can be compromised because the administrative username and password are configured in the same way for every CSS.
Note
The administrative username and password are stored in nonvolatile random access memory (NVRAM). Each time you reboot the CSS, it reads the username and password from NVRAM and reinserts them into the user database. SuperUser status is assigned to the administrative username by default.
You can change the administrative username and password, but because the information is stored in NVRAM, you cannot permanently delete them. If you delete the administrative username using the no username command, the CSS deletes the username from the running-config file, but restores the username from NVRAM when you reboot the CSS.
To change the administrative username and password through the Offline DM Main menu:
1.
2.
Enter <administrator> username (minimum 4 characters):3.
Enter <administrator> password:4.
Confirm <administrator> password:The CSS displays the Security Options menu.

Using the Disk Options
The Disk Options menu includes the following menu items:
•
•
•
Note
The Disk Options menu is as follows:
D I S K O P T I O N SEnter the number of a menu selection:1. Format Disk2. Check Disk3. Check Disk Disabler. Return to previous menuReformatting the Disk
If the CSS detects unrecoverable errors when performing a disk check, you must reformat the disk. Reformatting the disk erases all data from the disk permanently.
To reformat the disk:
1.
2.
The CSS prompts you to format the disk.
Formatting the disk results in all disk data being permanently erased.Are you sure you want to continue? (yes,no):3.
•
•
The CSS prompts you to perform a quick format or a complete format.
Quick format? (yes,no):4.
•
•
After the CSS reformats the disk, it displays:
Operation completed successfully.5.
6.
Because the disk is empty, you must configure a primary boot record to instruct the CSS where to locate the new ADI file containing the CSS software.
7.
If you do not set the primary boot configuration before booting the CSS, the boot process halts at the prompt:
Would you like to access the Offline Diagnostic Monitor menu?(y<cr>)You must enter the Offline DM Main menu to set the primary boot configuration.
Performing a Check Disk
During the check disk process, the CSS detects and recovers from the following error conditions:
•
•
•
•
•
•
When the CSS boots up, it also checks the results of the previous shutdown (as described in Chapter 1, Booting, Logging In, and Getting Started). If the CSS reports that the disk is dirty, it has discovered errors on the disk. In this case, the CSS automatically performs a disk check to recover from the errors and to maintain disk integrity.
The amount of time the CSS requires to perform a disk check is proportional to the number of installed files and directories on the disk. The greater the number of installed files and directories, the longer the CSS takes to complete the disk check.
Note
To perform a disk check:
1.
Correct errors if discovered (yes,no):2.
•
•
The CSS prompts you to perform a quick check of the disk.
Quick check disk? (yes,no):3.
•
•
The CSS performs the disk check. When completed:

Disabling or Enabling Disk Check
The Disk Options menu provides an option to disable or enable the running of check disk. When you select this option, it toggles to disable check disk if the option is currently enabled, or to enable check disk if the option is currently disabled.
Note
For example, if check disk is currently enabled, to disable it:
