Electrical and environmental requirements

Electrical fit

Power requirements

NOTE:
SAS drives do not have a regular 4-pin power connector and must be powered through the SAS
connector.
The following are the PSU requirements for FC and SAS half-height drives:
Voltage
5V
12V
See also details in Chapter 3, Electrical Requirements in Ultrium LTO-8 Tape Drives Technical Reference
Manual Volume 4 Specifications Guide.
The drive is specified to operate at 5V ±5% and 12V ±10%.

Voltage and current requirements

Voltage and current requirement are as follows:
Half-height drives
Specification
Max voltage
Min voltage
Peak Instantaneous Current
< 1ms
Max noise/ripple

Airflow requirements

HPE LTO Ultrium drives require forced airflow to ensure that components never exceed critical
temperatures. The following requirements and the operating temperature specification will keep the
internal temperature around the media to less than 45°C and ensure reliable operation.
The airflow will circulate or move from front to back at 3.0 cfm and does not require filtering if the air
contamination specifications are met. See Climatics in Chapter 5, Environmental in Ultrium LTO-8 Tape
Drives Technical Reference Manual Volume 4 Specifications Guide.
