IT & power

1. 1 · Define the required workstation

   Specify software, simultaneous uses, displays and retained peripherals. Request the proposed configuration: exact processor, memory, storage, ports and operating system/licences. A range name does not describe every computer variant.

2. 2 · List priority loads

   Separate what must stay powered from what may stop. Record power figures and units: watts and volt-amperes are not interchangeable. Both UPS output limits must be respected.

3. 3 · Set a runtime objective

   Output capacity and runtime are different questions. Request the manufacturer curve for the selected model, load and batteries. “Last until a clean shutdown” is a different need from “continue operating”.

4. 4 · Plan the end of backup operation

   Verify monitoring and shutdown functions for the systems in use. Define who receives alerts and organises authorised tests. Do not assume a USB or network connection automatically includes software, licences and compatibility with every workstation.

On small screens, scroll the table to compare all three columns.

1. 01

   An unambiguous inventory

   List every device to supply or retain, its quantity, role and reference. State whether consumption is measured, documented or unknown. Do not add figures in different units or hide missing data.

2. 02

   Priorities and dependencies

   For a till workstation, for example, specify whether the local network, router and required peripherals must also remain usable. This is a planning example: backing up the workstation does not guarantee the provider’s Internet connection or external services.

3. 03

   Installation and operation

   Specify rack or desk, available space, ventilation, existing outlets and technical contact. Clarify included accessories and work, any monitoring, operating instructions and battery-replacement conditions. No maintenance contract is implied.

Standby, line-interactive and double-conversion designs differ; regulation and battery-transfer behaviour must suit the protected equipment. Have topology, outlets and load conditions validated. Do not apply one universal W/VA factor to every device.

A UPS is not a file backup. Distinguish power loss, hardware failure and data loss in your request. Computers, drives and peripherals in this category also need to be matched to their actual use; catalogue grouping does not validate an assembly.
