Flash
FWSM contains a 128 MB Compact Flash, which is partitioned into six sizes for different tasks as shown in Table 4-1.
| Partition Number | Size (MB) | Description |
|---|---|---|
| First (cf:1) | 16 | Maintenance Partition |
| Second (cf:2) | 7 | Network Configuration |
| Third (cf:3) | 1 | Crash Dump Partition |
| Fourth (cf:4) | 20 | Application Partition1FWSM file systemimage, configuration, and PDM file |
| Fifth (cf:5) | 20 | Application Partition2FWSM file systemimage, configuration, and PDM file |
| Sixth (cf:6) | 64 | Reserved |
Typically, you will be working with cf:1, cf:4 or cf:5 partitions. If you set the boot device for cf:4 or cf:5, the FWSM will boot up in normal mode (application partition). However, if you set the boot device for cf:1, the module will boot up as Maintenance, which can be used to re-image or perform the password recovery for the Application partition (cf:4 or cf:5). More details on setting up the Boot Device follow in the next section.
