Service Inspection Safety Procedures
Introduction
A safety inspection procedure for the 2220 should be performed:
When it is inspected for an IBM agreement
When IBM service is requested and no service has recently been performed by IBM
When an alterations and attachments review is performed
When changes have been made to the equipment that might affect its safety.
If the inspection indicates unacceptable safety conditions, the conditions must be corrected before IBM
services the equipment.
Note: The correction of any unsafe condition is the responsibility of the owner of the equipment.
The 2220 areas and functions checked through these procedures are:
1. External covers
2. Safety labels
3. Grounding (earthing)
4. Circuit breaker and circuit protector rating
5. Input power voltage
6. Power ON indicators
7. Emergency power OFF of the board
8. Cooling
Steps 1 through 8 must be performed Power OFF, as follows:
Main CBs switched OFF on the 2220.
All the equipment installed in the 2220 rack or connected to it is OFF.
Power supplies at customer premises are switched OFF.
On the 2220 do not remove the power cords and ground wire .A/ in order to maintain the ground
protection (see Figure 0-1 on page xix).
1.External Covers
Check that:
All external covers are present on the 2220.
Appropriate service clearances and accesses are provided around the racks with external covers
opened.
Leave all external covers opened to allow further inspection steps.
2.Safety Labels
Check that:
All the safety labels are at the places indicated by letters in “Safety Label Locations” on page xl.
Each label corresponds to the correct model as indicated by the letter as shown in “Safety Label
Identifications” on page xliv.
xviii 2220 Models 300, 500, and 501: Service Guide
To check the labels on the ACDC and/or DC48 power input and on the battery (if present) you must
remove these FRUs. Refer to Chapter 6, “2220 FRU Exchange” on page 6-1 for detailed instructions.
3. Grounding (Earthing)
Note
