1.3.5 Hazardous Materials
Design of the CoolShell CS-3U is compliant with the standards IAW 29 CFR 1910,
Subpart H and Z, FED STD 313, 40 CFR Chapter I, J, abd SD14. The CoolShell CS-
3U does not use ozone-depleting materials as defined in IAW SD 14 and 40 CFR
Chapter I, Subchapter C.
As is the case with all commercial computer equipment, a lithium battery is used to
retain configuration information and support the real-time clock in the computer sys-
tem. Some PVC is used for insulation material on internal components.
1.3.6 CPU Blade
The primary components of the CPU Blade consist of an off-the-shelf Xeon mother-
board, an I/O Module, and two PCI or PCI-Express daughter cards, depending on the
type of riser cards that are used. Total power specifications for the CPU Blade are
given in
Table 1-5 on page 1-8.
