GBase-T /O module can be added in slot 10 alongside the HA interconnect I/O module in
slot 11.
Internal System Components
The storage processor (SP) is a subassembly within the chassis that contains the
memory risers with the DIMMs and a fan tray with fan modules. The SP module also
contains the 4 CPUs, which cannot be removed or replaced.
l
The memory risers tray, which contains 8 memory risers with DIMMs, can be
accessed from the front of the SP module. The memory risers are not hot
swappable
l
The fan tray, which contains 8 fan modules, can be accessed from the front of the
SP module. The fans are hot swappable.
The DIMMS can be accessed by pulling the entire SP module away from the chassis.
Depending on the model, there are DIMMs totaling:
l
256 GB or 512 GB for a DD9500 system.
l
256 GB or 768 GB for a DD9800 system.
The figures show the location of the SP module, the DIMM risers accessed from a
partly removed SP module, and the fan tray partly removed.
Do not lift the DD9500/DD9800 system, or the storage processor (SP) module, or
any modules by the handle. The handle is not designed to support the weight of the
populated shelf. Also do not carry the DD9500/DD9800 system or the SP by the
handle. The handles are only intended to be used to insert or remove the SP module.
