General Product and Safety Information
This product meet IBM safety standards.
Safety Notice for United Kingdom
The network adapter interfaces housed within the IBM 8265 Nways ATM Switches are approved
separately, each one having its own independent approval number. These interface adapters, supplied by
IBM, do not use or contain excessive voltages. An excessive voltage is one that exceeds 42.4 V peak ac
or 60 Vdc. They interface with the IBM 8265 Nways ATM Switch using Safety Extra Low Voltages (SELV)
only. In order to maintain the separate (independent) approval of the IBM adapters, it is essential that
other optional cards, not supplied by IBM, do not use mains voltages or any other excessive voltages.
Seek advice from a competent engineer before installing other adapters not supplied by IBM.
Service Inspection Safety Procedures
Introduction
A safety inspection procedure for the 8265 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 machine.
Note: The correction of any unsafe condition is the responsibility of the owner of the equipment.
The 8265 areas and functions checked through these procedures are:
1. External covers
2. Safety labels
3. Safety covers and shields
4. Grounding (earthing)
5. Input power voltage
6. Power control switch
7. Power OFF
Steps 1 through 6 must be performed after power OFF as follows:
1External Covers
Check that:
They are all present on the 8265.
They are locked.
They can be fully opened.
Appropriate service clearance and access are provided around the 8265 with external covers
opened.
Leave all external covers opened to allow further safety inspection steps.

2Safety Labels
Check that:
All the safety labels are at the places indicated by letters in “Safety Label Locations” on
page xxi.
Each label is of the model corresponding to the letter as shown on “Safety Label Identification”
on page xxii.
3Safety Covers and Shields
Check that all the safety covers are present and secured with screws.
4Grounding (Earthing)
aGrounding of the 8265 to the Premises Grounding System
Note
In this manual, "ground" means that the equipment must be connected to the earth.
Check that:
Electrical continuity is assured between the 8265, frame grounds, and to the premises
grounding system, through the 8265 power cords.
bac/dc Power Cable Ground Wire
Check the mainline ac/dc power cable for damaged or burned pins and broken insulation.
Measure the resistance of the disconnected mainline ac power cable from ground pin on
one end to the ground pin on the other end.
The measurement should be 0.1 ohms or less.
