Chapter: Using the SD Flash Memory Module
Using the SD Flash Memory Module
This chapter describes the Secure Digital (SD) flash memory module (or SD card) that is used with the Cisco ME3800, ME3600 and ME3600X-24CX Switches, and includes instructions for installing and removing the SD card.
SD Flash Memory Module
The router features an SD card slot, which supports a single Cisco SD flash memory module (SD card) and SD High Capacity (SDHC). The SD card stores router data and software, including:
- Switch operating software
- Running configurations
- Network management software configuration
- Network registration data
- Switch firmware
- Crashinfo file and core dump on sdflash
- Syslog messages
- Archive download of latest IOS from the tar image present on sdflash
The SD card uses a DOSFS file system. The switch configuration is stored in a binary file in an invisible partition on the card.
Supported SD Cards
Table 30-1 lists the SD cards that can be used with the router.

Accessing the SD Card
The SD card and SD card LED are accessed from the switch front panel, though the switch SD card slot, shown in Figure 30-1.
Do not remove the SD card from the router; removing the SD card will cause the router to stop operating.
SD Card Status
You can check the SD card status by viewing the SD Card LED.
SD Card LED
The SD card LED is located directly next to the SD card slot. This section describes the LED states and descriptions.

Insertion and Removal of Card
The sd card is not hot swappable. When the SD card is inserted and removed the syslog messages shown below are logged:
Note The sdflash should not be removed while sdflash write is in progress.
Configuration Restrictions
Configuring SD Flash Card
To configure SD flash card feature use the following steps.
Transferring Running Configuration
To transfer running configuration file from one system to another use the following steps:
Step 1 Insert sd flash card in first system
Step 2 Use copy running-config command to copy running-config to the sd flash card:
Step 3 When copy operation is completed, remove the sd flash card from the first system and insert sd flash card in second system. Ensure SD Flash LED is ON.
Step 4 Use config replace command to overwrite existing configuration.
Transferring Start-up Configuration
To transfer start-up configuration file from one system to another use the following steps:
Step 1 Insert the sd flash card in first system
Step 2 Use copy tftp command to copy startup configuration file.
Step 3 When copy operation is completed, remove the sd flash card from the first system and insert sd flash card in second system. Ensure SD Flash LED is ON.
Note Ensure the SD card is inserted and has the startup-config file on it.
Step 4 Use logging file sdflash command to enable copying of syslogs to sdflash:
Step 5 Use boot config-file sdflash command to configure system to use configuration on SD Flash while booting.
Step 6 Use the boot system sdflash:image_name command to use image from sd flash card while booting.
Step 7 Use the boot config-file sdflash:startup-config command to set boot with the configuration file on sd flash card.
Step 8 Use the logging file sdflash:syslog.log nomax 7 command to set the syslog messages to be saved onto to sd flash card
Step 9 Use the archive download-sw /overwrite sdflash:<image name>.tar command to archive download from sd flash card
Configure Core and Crash information
To configure the system to dump core and crash files into sd flash card use the following steps:
Step 1 Use exception flash all sdflash: command to dump core and crash info files to the sdflash card:
Step 2 Use the exception core-file command to set core dump filename:
Step 3 Use the exception crashinfo command to set crash info filename:
