+# Cisco Catalyst 9500
+
+## Firmware Upgrade
+
+### Check the existing install method:
+```
+show version | i System image
+```
+
+If output show's filename ending in *.bin == **BUNDLE**
+If output show's filename "packages.conf" == **INSTALL**
+
+```
+show install summary
+```
+
+If output show's details == **INSTALL**
+If output show's "Bundle" == **BUNDLE**
+
+### Verify
+Verify the `boot` commands in the config are correct:
+
+  - `packages.conf` == INSTALL
+  - `*.bin` == BUNDLE
+
+If using INSTALL do not change or modify the `boot` commands or the `packages.conf` file.
+
+
+### Remove unused firmware files
+This makes more room available on the storage of the device as firmware images are quite large.
+
+```
+install remove inactive
+```
+
+### Copy firmware file to device
+Use, `scp` or any other available method.
+
+
+### Verify the firmware hashes
+
+```
+verify /md5 flash:<filename.bin>
+```
+
+Ensure the hash of the file and the reported hashes match.
+
+### Install
+```
+install add file flash:<filename.bin> activate commit
+```
+This command will:
+  - Unpack the `*.bin` image
+  - Update the `packages.conf` file
+  - Commit the new packages
+
+### After reboot, Verify
+Use the same verification commands in step 1: `show version`, `show install summary`
