Cisco Systems 7936 Manual De Usuario

Warning

Ultimate disposal of this product should be handled according to all national laws and
regulations.

Warning

Do not work on the system or connect or disconnect cables during periods of lightning
activity.

Warning

To avoid electric shock, do not connect safety extra low voltage (SELV) circuits to
telephone network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN
ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use
caution when connecting cables.

Warning

This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S.
(240 VAC, 10 A international) is used on the phase conductors (all current-carrying
conductors).

Warning

The plug-socket combination must be accessible at all times because it serves as the
main disconnecting device.

Caution

The Cisco Unified IP Conference Station 7936 is inoperable during a power outage if it is
not supported by a UPS (uninterruptible power supply) when using a local power supply
unit. This affects your ability to reach 911.

Caution

Using a cell, mobile, or GSM phone, or a two-way radio in close proximity to a
Cisco Unified IP Phone might cause interference. For more information, refer to the
manufacturer’s documentation of the interfering device.
