Uninterruptible Power-Supply Requirements; Emergency Power-Off Shutdown; Handling Static-Sensitive Devices - IBM SAN Volume Controller 2145-CG8 Hardware Maintenance Manual

Using the following inspection checklist as a guide, inspect the uninterruptible power supply for unsafe
conditions. If necessary, see any suitable safety publications.
1. If any equipment has been damaged during the shipment, keep the shipping cartons and packing
materials.
2. To file a claim for the shipping damage, perform the following steps:
a. File with the carrier within fifteen days of receipt of the equipment.
b. Send a copy of the damage claim within fifteen days to your service support representative.

Uninterruptible power-supply requirements

Ensure that you comply with the requirements for the uninterruptible power supply.
The following list describes requirements for the 2145 UPS-1U:
v The voltage that is supplied to the 2145 UPS-1U must be 200-240 V single phase.
v The frequency that is supplied must be 50 or 60 Hz.
Note: The 2145 UPS-1U has an integrated circuit breaker and does not need external protection.
Attention:
v If the uninterruptible power supply is cascaded from another uninterruptible power supply, the source
uninterruptible power supply must have at least three times the capacity per phase and the total
harmonic distortion must be less than 5%.
v The uninterruptible power supply also must have input voltage capture that has a slew rate of no
more than 3 Hz per second.

Emergency power-off shutdown

The SAN Volume Controller and each uninterruptible power supply support emergency power-off (EPO)
shutdowns.

Handling static-sensitive devices

Ensure that you understand how to handle devices that are sensitive to static electricity.
Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep
static-sensitive devices in their static-protective bags until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
v Limit your movement. Movement can cause static electricity to build up around you.
v Handle the device carefully, holding it by its edges or frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the device.
v While the device is still in its antistatic bag, touch it to an unpainted metal part of the system unit for
at least two seconds. (This action removes static electricity from the package and from your body.)
v Remove the device from its package and install it directly into your SAN Volume Controller, without
putting it down. If it is necessary to put the device down, place it onto its static-protective bag. (If your
device is an adapter, place it component-side up.) Do not place the device onto the cover of the SAN
Volume Controller or onto a metal table.
v Take additional care when you handle devices during cold weather because heating reduces indoor
humidity and increases static electricity.
