Power Cabling
Each ShoreTel voice switch comes equipped with a standard 110 VAC modular power cord. A
localized modular power cord can be ordered from ShoreTel. ShoreTel recommends that every
ShoreTel voice switch, as well as the ShoreTel server, be connected to an uninterruptable power
supply (UPS).
Ethernet Cabling
Each ShoreTel voice switch has two RJ-45 connectors that provide an auto-sensing 10/100M Ethernet
interface. These are connected to the local area network using standard Category 5 cabling.
ShoreTel voice switches come with two network interfaces, LAN1 and LAN2, allowing for a network
fault tolerant deployment. You can connect to either or both connectors; there is no primary/secondary
relationship. When both are connected, only one will be active at any time. If the currently active
interface loses the link, the alternate interface becomes active. Both interfaces will use the same MAC
Ethernet address, and IP address.
There are two levels of fault tolerance. To protect against Ethernet switch failure, connect LAN1 and
LAN 2 to separate Ethernet switches. To protect against port or cable failure, connect LAN1 and LAN2
to separate ports on the same Ethernet switch.
10 Base-T and 100 Base-T can typically support up to 100 meters.
IP Phone Cabling
Each ShorePhone IP phone has an RJ-45 connector that provides an auto-sensing
10/100M Ethernet interface. This is connected to the local area network using standard Category 5
cabling.
10 Base-T and 100 Base-T can typically support up to 100 meters.
Analog Telephone and Trunk Cabling
ShoreTel voice switches that support analog protocols provide an RJ-21X male connector for mass
termination of the telephones and trunks. This should be connected using a standard 25-pair cable.
ShoreTel recommends using the RJ-21X and connecting to a patch panel to provide simple moves,
adds, and changes.
Telephones can be supported from 0 to 2,000 feet from the voice switch over standard cabling. Use
larger gauge wires for longer distances.
It is recommended that an analog telephone be provisioned in the equipment room for troubleshooting
purposes.
Pinout information for ShoreTel Voice Switches is provided in the quick install guide for each voice
switch.
