b. The uninterruptible power supply from the ground pin of the input power receptacle to the
ground conductor of the output power receptacle
c. If used, the redundant ac-power switch from the ground pin of the main input power
receptacle to the ground conductor of the output power receptacle, and from the ground pin of
the backup input power receptacle to the ground conductor of the output power receptacle
d. The SAN Volume Controller node to uninterruptible power-supply power-cable assembly,
between the two ground conductors of the power cable
e. The uninterruptible power-supply input-power cable, between the two ground conductors of
the power cable
f. If used, the redundant ac-power switch main input-power cable, between the two ground
conductors of the cable
g. If used, the redundant ac-power switch backup input-power cable, between the two ground
conductors of the cable

Inspecting the uninterruptible power supply for unsafe conditions

Ensure that you take the time to inspect the uninterruptible power supply for unsafe conditions.
Consider the following conditions and their potential safety hazards:
Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
A bulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious injury.
Use caution when working in a potential safety hazard that is not covered in the safety checks. If unsafe
conditions are present, determine how serious the hazards are and whether you can continue before you
correct the problem.
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.
