U Series 9 Product Manual, Rev. C 2.12 Electromagnetic immunity When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in the following table: Performance Reference Test...
Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in represen- tative end-user systems.
As a subassembly, no Federal Communications Commission verifica- tion or certification of the device is required. Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules.
U Series 9 Product Manual, Rev. C Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. Handling and static discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
U Series 9 Product Manual, Rev. C Jumper settings 3.2.1 Master/slave configuration The options jumper block shown in Figure 3 is used to configure the drive for operation. It is the 8-pin dual header between the interface connector and the power connector.
U Series 9 Product Manual, Rev. C 3.2.3 Alternate capacity jumper Some older computers may “hang” at startup if their BIOS detects a disc drive with a capacity greater than 32 Gbytes. This limits the drive’s capacity to 32 Gbytes when the alternate capacity jumper is used. To access the full capacity of the drive, you can: •...
U Series 9 Product Manual, Rev. C Drive mounting You can mount the drive in any orientation using four screws in the side- mounting holes or four screws in the bottom-mounting holes. See Figure 5 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive: •...
U Series 9 Product Manual, Rev. C ATA interface These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.
