Electrical Power Source
Warning
Do not open the gateway or remove the network interface card (NIC) from
the gateway. No user-serviceable or user-replaceable parts are present in
the gateway. Only authorized service personnel should repair or open the
gateway.
Warning
To reduce the risk of fire, electric shock, and injury, disconnect the power
cord and any cables that connect to the gateway before you open the
chassis and expose internal components. Even though the power switch
is turned off, power is still present inside the gateway.
The gateway requires a clean and well-regulated power source, free from
power surges and line noise. When the gateway is configured as a cluster
(rather than as a standalone gateway), each gateway should have its own
power source installed on a circuit separate from all other gateways in the
cluster. This ensures that a power failure on one circuit can affect only one
device within the cluster.
All gateways incorporate an autosensing power supply device that uses either
low range (100 to 130 VAC), or high range (200 to 240 VAC) at
50 to 60 Hz. Check the gateway safety label for specifics.
Product Disposal
At the end of its useful life, the gateway must be disposed of in accordance
with all national, state, and local laws and regulations. The device contains
components (such as its lithium battery) that must be disposed of properly to
prevent damage to the environment. Contact your local waste management
agencies for specific guidelines.
