Rackmount Safety Instructions
•
Elevated Operating Ambient:
If installed in a closed or multi-switch rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature, as specified in Operating/Storage Environment, page 5.
•
Reduced Air Flow:
Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
•
Mechanical Loading
: Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
•
Circuit Overloading:
Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing
this concern. For reliability reasons the PoLRE switch should be powered from a dedicated mains
outlet.
•
Reliable Earthing:
Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit
(e.g. use of power strips).
Replacing Legacy Devices with IP Endpoint Devices
CAUTION
:
To ensure trouble-free synchronization with the PoLRE switch upon startup, all IP
endpoint devices must be installed before you connect the PoLRE switch to a power source.
To replace the legacy devices with IP endpoint devices:
1.
Important
: Remove all legacy analog/digital phones and fax machines from their telco jacks (RJ11
wall plugs) before you carry out any further installation steps.
2.
Connect the new IP phones to the Phylink adapters: Plug the IP phone to the RJ45 side of the Phylink
adapter using a standard Ethernet cable.
3.
Plug the other end of the Phylink adapter into the RJ11 wall plug using a standard CAT3 cable. From
the RJ11 of the Phylink adapter to the wall jack, the existing silver satin can be used when doing a
DNIC/POTS replacement. For BT-type wall plate connectors, use the optional BT Adapter Cable
instead.
