Error messages are displayed when a file write fails. Failure could be due to the
card being removed or an error in the card itself. For information about CFlash
commands, see the Managing the File System chapter in the Software Reference.
Dual In-line Memory Module (DIMM)
Synchronous DRAM (SDRAM) is provided by a single DIMM for AT-8900,
AT-9900, and AT-9900s switches. Only DIMMs supplied by Allied Telesyn have
been tested and approved for use. Using unapproved DIMMs may cause
unreliable operation and will invalidate the warranty for the switch.
The following DIMMs have been approved for use with AT-9924T and
AT-9924SP switches:
AT-SD128A-00 128 MB SDRAM (factory installed)
■
AT-SD256A-00 256 MB SDRAM (upgrade)
■
The following DIMMs have been approved for the AT-9924T/4SP switch
without the AT-ACC01 network processor accelerator card:
AT-SD256A-00 256MB SDRAM (factory installed)
■
AT-SD512A-00 512MB SDRAM (upgrade)
■
For an AT-9924T/4SP switch with an AT-ACC01 network processor accelerator
card, the following DIMM is required:
AT-SD512A-00 512MB SDRAM (factory installed when the switch is
■
ordered with an AT-ACC01 fitted)
The AT-9924Ts switch is shipped with a 512 MB SDRAM DIMM; no upgrades
are available.
Warning Only authorised service personnel should install DIMMs. Opening
the switch's lid may cause personal injury from electric shock and could
damage the switch.
The switch is unlikely to boot unless the DIMM is correctly installed. If the
switch does boot but you suspect the DIMM is malfunctioning, display system
information by using the show system command. See
on page 34
for output.
