NOTE
NOTICE
A dry contact is a set of two switch contacts, like a set of contacts from a
relay or from a toggle switch, etc., that has both terminals available and
neither contact is connected to power. (Dry = no power) The contacts may be
NO, normally open (also called form A), or NC, normally closed (also called
form B). Form C would be a SPDT (single pole double throw) with 3
connections. You can connect the contact to any type of monitoring device
you want, regardless of whether the device is already connected to power or
any other circuit.

See SNMP Query, on page 5-1.

Cabling
There are three types of interface connectors used for the TC8518.
•
The RJ-45(10/100 Base-T) Ports at the front of the TC8518 are accessed by
using RJ-45 Ethernet connections. Be careful when inserting this type of
connector as it is the weak point in any Ethernet cable.
•
The Console (CON) Port at the bottom of the chassis is accessed through RS-
232 Serial interface. Users will need a straight-through DB9 cable to connect
the PC to the console port.
•
T1/E1 ports on the TC8518 are accessed using T1 RJ-48 straight-through
(ex.Channel Bank) or cross-over (ex. Cisco Router).
