WARNING: U.K. only:
If connecting a modem to the console port of the Switch 4500, only use a
modem which is suitable for connection to the telecommunications
system.
WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot
be used as standard traditional telephone sockets, or to connect the unit to a
traditional PBX or public telephone network. Only connect RJ-45 data
connectors, network telephony systems, or network telephones to these
sockets.
Either shielded or unshielded data cables with shielded or unshielded
jacks can be connected to these data sockets.
WARNING: Fiber Optic ports – Optical Safety
Never look at the transmit laser while it is powered on. Never look directly
at the fiber TX port and fiber cable ends when they are powered on.
WARNING: This device has more than one power input. Disconnect all
power inputs to power off this device.
WARNING: The installation of the Redundant Power Supply (RPS) should
only be carried out by properly trained and qualified personnel.
WARNING: These instructions must be read in conjunction with the RPS
flyer and the safety and installation instructions supplied with your RPS.
WARNING: When powering any Switch 4500 from an RPS, the unit must
be earthed (grounded). This can be achieved by either connecting the
power cord to the unit or by connecting the earth terminal on the rear of
the unit to a reliable electrical earth, or by connecting both. It must be
ensured that the earth connection is made before connecting the DC
supply from the RPS.
