Installing the 2145 UPS-1U in the rack
After you have completed the preparation procedures, you are ready to install the
2145 uninterruptible power supply-1U (2145 UPS-1U) in the rack.
Attention: Read all safety and environmental notices before you start the
installation process. Use the reference numbers in parentheses at the end of each
notice to find the matching translated notice. For the translation of the danger,
caution, attention notices, and the translation of the safety labels, see the IBM
Systems Safety Notices.
CAUTION:
The 2145 UPS-1U contains its own energy source (sealed, lead-acid batteries).
The output receptacles might carry live voltage, even when the 2145 UPS-1U is
not connected to an ac supply. (11)
CAUTION:
Do not remove or unplug the input cord when the 2145 UPS-1U is turned on.
This removes the safety ground from the 2145 UPS-1U and the equipment
connected to the 2145 UPS-1U. (12)
CAUTION:
To reduce the risk of fire or electric shock, install the 2145 UPS-1U in a
temperature- and humidity-controlled indoor environment, free of conductive
contaminants. Ambient temperature must not exceed 40°C (104°F). Do not
operate near water or excessive humidity (95% maximum). (13)
CAUTION:
To avoid any hazard from the rack tipping forward when devices are installed,
observe all safety precautions for the rack into which you are installing the
device.
