6. From the File Type menu, select the type of file:
• Software. The system software image, which is saved in one of two flash sectors
called images (image1 and image2). The active image stores the active copy, the
other image stores a second copy. The device boots and runs from the active image.
If the active image is corrupted, the system automatically boots from the nonactive
image. This is a safety feature for faults occurring during the boot upgrade process.
This the default setting.
• Text Configuration. A text-based configuration file enables you to edit a configured
text file (startup-config) offline as needed. The most common usage of
text-based configuration is to upload a working configuration from a device, edit it
offline to personalize it for another similar device (for example, change the device
name, serial number, IP address), and download it to that device.
• SSL Trusted Root Certificate PEM File. SSL Trusted Root Certificate File (PEM
Encoded).
• SSL Server Certificate PEM File. SSL Server Certificate File (PEM Encoded).
• SSL DH Weak Encryption Parameter PEM File. SSL Diffie-Hellman Weak
Encryption Parameter File (PEM Encoded).
• SSL DH Strong Encryption Parameter PEM File. SSL Diffie-Hellman Strong
Encryption Parameter File (PEM Encoded).
7. If the selection from the File Type menu is Software, the Image Name menu is displayed
and you must select the software image that must be downloaded to the switch:
• image1. Select image1 to upload image1.
• image2. Select image2 to upload image2.
Note: We recommended that you do not overwrite the active image. If you do
so, the switch displays a warning that you are trying to overwrite the
active image.
8. Click the Browse button and locate and select the file that you want to download.
The file name can contain up to 80 characters.
9. Click the Apply button.
The file transfer begins.
The page displays information about the progress of the file transfer. After a file transfer is
started, wait until the page refreshes. When the page refreshes, the option to select a file
option is no longer available, indicating that the file transfer is complete.
Note: After a software image file is downloaded, you might need to select
the new software image file (see
Change the Software Image That
Loads When the Switch Starts or Reboots on page 333) and reboot
the switch. After a text configuration file is downloaded, the switch
applies the configuration automatically.
