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:

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
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.
Table 2. Radiated Emissions
Susceptibility and ESD Limits
Table 3 and Table 4 list radiated, magnetic radiated, and conducted susceptibility and ESD failure level limits for the tape drive.
