Back to Contents Page Regulatory Compliance: Dell™ PowerVault™ 110T SDLT 320 Tape Drive User's Guide • Safety Regulations • Electromagnetic Field Specifications • Acoustic Safety Regulations This section lists the safety regulations that the PowerVault 110T tape system meets or exceeds, such as UL, CSA, EN/IEC, and "GS" Mark. Safety Certifications The SDLT tape system meets or exceeds requirements for safety in the United States (UL 1950), Canada (CSA950 C22.2 No. 950) and Europe (EN60950/IEC 950), and is certified to bear the GS mark. Safety Requirements Safety requirements include: UL1950: Information Technology Including Electrical Business Equipment CSA950 C22.2 No. 950: Information Technology Including Electrical Business Equipment EN60950/IEC 950: Information Technology Including Electrical Business Equipment Electromagnetic Field Specifications Electromagnetic Emissions Once the internal tape drive is mounted into an enclosure and grounded, the internal drive complies with FCC Class A; the external tape drive complies with the FCC Class B limits. Conducted Emissions Limits for Class B equipment are in the frequency range from 0.15 to 30 MHz. Table 1. Conducted Emissions Frequency Range 0.15 to 0.50 MHz 0.50 to 5 MHz 5 to 30 MHz * The limit decreases linearly with the logarithm of the frequency. Quasi-peak 66 to 56* 56 60 Limits dB Average 56 to 46 46 50 Radiated Emissions Limits of radiated interference field strength, in the frequency range from 30 MHz to 1000 MHz at a test distance of 10 meters, are listed in Table 2.
