It is strongly recommended that the airflow be measured while the ZT 5515 is installed in its
intended location. Insert a thermistor type air velocity meter (Kane-May KM4007* or similar)
through the PMC access on the faceplate and make the air velocity measurement near the processor
heat sink. Power should not be applied to the ZT 5515 during airflow measurements (slightly
disengage the ZT 5515 from the backplane connectors if necessary).
The processor “core” temperature must never exceed 100° C under any condition of ambient
temperature or usage. This may result in permanent damage to the processor.
The ZT 5515 may contain materials that require regulation upon disposal. Please dispose of this
product in accordance with local rules and regulations. For disposal or recycling information,
please contact your local authorities or the Electronic Industries Alliance at http://www.eiae.org/.
Memory Configuration
The ZT 5515 components can address up to 4 Gbyte of memory, but since the board has only one
DIMM socket it can physically only hold up to 1 Gbyte of memory. Also, there is a lack of
manufacturers of single sticks of 2 Gbyte SDRAM (DDR unregistered, unbuffered, ECC/non-
ECC) at 200 or 266 MHz.The address space is divided between memory local to the board and
memory located on the Local PCI bus. Any memory not reserved or occupied by a local memory
device (DRAM/flash) is available to PCI memory devices.
The ZT 5515 can support a single stick of either 256 Mbyte, 512 Mbyte or 1 Gbyte ECC DDR
SDRAM in a single 90° angle DIMM socket. 512 KByte of L2 cache is integrated with the Mobile
Pentium
16 Mbyte of local flash memory is soldered directly to the board and is divided into one hundred
and twenty eight 128-KByte erase blocks. The on-board BIOS is stored in the first 1 MB of this
local flash, the rest is open for customer use. For example, a VxWorks operating system could be
loaded into the upper 15 Mbyte and could be used as a boot device.
