General Safety Information
Only trained and authorised personnel should be permitted to work on this equipment. It is assumed that
those using this guide are competent to work on equipment of this nature and will take appropriate
precautions when working with the fault analysis guide.
Parallax Digital Technologies accepts no responsibility for any injury or loss caused by unsafe or inadequate
working practices, or for work carried out by an unauthorised third party.
To prevent possible danger, damage, and bodily harm when handling the equipment, please observe all
warnings, cautions notices contained in this section.
Failure to heed the following danger, warnings, and cautionary statements could lead to serious injury or

3.2
Mains Supply
The Unit should be mains-fed using the supplied AC Power Lead, which is fitted with a 3A Fuse. If the
device is to be fed from an alternative power source, then the appropriate circuit protection device should
be used to ensure that the supply circuit is interrupted, in the event that a fault in the device causes too
much current to flow into it, causing an unsafe condition.
3.3
Fibre-Optic Ports
This device incorporates Fibre Optic transmission ports – under no circumstance should anyone look
directly into these ports, as this may cause temporary or permanent damage to the users’ eye(s).
3.4
‘Hot’ PoE Ports
This switch is a Passive PoE device which means that the PoE power is continuously supplied to the RJ45
Connector and there is no handshake process that must complete before power is applied to the ports, as
with IEEE 802.3af and IEEE 802.3at compatible devices. Designers and operators should ensure that all
devices are compatible with this type of connection method.
