devices are equipped with an SD card slot to allow the

to save more syslog information and store more files with the File Server feature. SD cards with a maximum storage capacity of 32 GB are supported. The file size limit is 4 GB. SD card capabilities are configured from the

GUI or the CLI. SD card capability is disabled by default, and if your

device does not have an SD card slot, the configuration option will not be visible in the GUI.

Before you Begin

  • The SD card should be inserted into the SD card slot and mounted on the system.
  • If the SD Card feature is enabled before the card is inserted, the feature needs to be disabled and then re-enabled from the configuration GUI.

  • The SD Card feature should be disabled before the card is removed from the SD card slot.

    Caution

    Ribbon recommends removing the SD card while it is mounted and in use. Data may be lost, the system may crash, and the system may require a reboot before a re-inserted card can be remounted.

Enabling the SD Card

This section outlines how to enable the SD card.

To Enable the SD Card

  1. Insert an SD card into the
    Unable to show "metadata-from": No such page "_space_variables"
    4700 Series SD card slot.

  2. Choose Admin > SD Card.

  3. Select the Enable SD Card checkbox and click Submit.

  4. Proceed to Managing the SD Card.

    Caution

    When the SD Card feature is enabled, and the SD card is mounted, the default Admin page displays a warning upon login that the SD card is enabled and that system performance may be degraded. The CPU is needed when logging or writing capture files to disk, which can reduce data throughput and system call capacity.

    If no SD card is present on the system, an error message appears in the SD Card information window.

  4. Click Submit to save your settings.
