Displaying data
about an SD card
To display information about a Secure Digital card, including card size, file
count, and volume label, insert the card and enter the command:
show card
The following figure is an example of output from the show card command.
You can also use the show card command to verify whether the switch
recognises the card. For more information about this command, see the
Managing the File System chapter in the Software Reference for Software 3.1.1.
Testing the slot You can test the SD card slot on front of the switch to verify that the hardware
does the following:
■ detects the presence of a card
■ detects whether a card has been exchanged
■ detects write-protection on a card
■ transfers data to and from a card
The test does not write data to the card or harm existing data. To test the slot,
use the command:
enable test device=card type=slot
Output is sent to the management asynchronous port. For more information
about testing the card slot, see the Test Facility chapter in the switch’s Software
Reference for Software 3.1.1.
Dual In-line Memory Module (DIMM)
Synchronous DRAM (SDRAM) is provided by a single DIMM for the x900
Series switches. Only DIMMs supplied by Allied Telesis have been tested and
approved for use. Using unapproved DIMMs may cause unreliable
operation and will invalidate the warranty for the switch.
AT-8948
x900-48FE
AT-9900
AT-SD256A-00 with 256MBytes SDRAM (factory installed or upgrade) has
been approved for use with AT-9924T, AT-9924SP, and AT-9924T/4SP models.
The following DIMMs have been approved for the AT-9924T/4SP switch
without an AT-ACC01 network processor accelerator card:
■ AT-SD256A-00 256MBytes SDRAM (factory installed)
■ AT-SD512A-00 512MBytes SDRAM (upgrade)
For an AT-9924T/4SP switch with an AT-ACC01 network processor accelerator
card, AT-SD512A-00 with 512MBytes SDRAM is required. It is installed at the
factory when the switch is ordered with an AT-ACC01 fitted.
AT-9924Ts
x900-24X
AT-9924Ts and x900-24X switches are shipped with a 512 MBytes SDRAM
DIMM; no upgrades are available.
