USB Type A Port
The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB
keys).
The USB Type A port provides these features:
The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB devices with port
densities of 128 MB, 256 MB, 1 GB, 4 GB, 8 GB are supported). When combined with stacking, you can
upgrade other switches in the stack from an USB key inserted in any switch within the stack. Cisco IOS
software provides standard file system access to the flash device: read, write, erase, and copy, as well as the
ability to format the flash device with a FAT file system. It provides you with the ability to automatically
upgrade the internal flash with the USB drive’s configuration and image for emergency switch recovery using
USB auto-upgrade. This feature checks the internal flash for a bootable image and configuration and if either
image or the configuration is not available, then the USB drive is checked for boot images and configuration.
If the boot image and configuration are available, these are copied to flash for the reboot.
SFP and SFP+ Module Slots
The switch has either two or four 1-Gigabit SFP or two 10-Gigabit SFP+ module slots. The slots marked
SFP+ support both SFP and SFP+ modules. The SFP slots support only the SFP modules.
