Upon power-up, the Supervisory port can send out diagnostic messages until
the Supervisory service acquires the port. These diagnostic messages can
disrupt the connected device; however, you can configure the unit to disable
their transmission.
NOTICE: A null modem (crossover) cable is required to connect a modem to the
Supervisory port.
Auxiliary Port
The AUXILIARY PORT is also a DB-9 female DCE connector that supports the
same configurable parameters as the Supervisory port with the addition of
flow control. The Auxiliary port speeds are also the same as the Supervisory
port’s and the defaults are the same. However, the Auxiliary port’s only
function is to support asynchronous data transmission (i.e., SCADA).
10/100 Ethernet
The WANsuite 5370 provides one 10/100 ETHERNET interface for SNMP and
Web browser access and for access to the IP Gateway feature. This interface
is an eight-pin modular jack that complies with standard twisted-pair,
10/100Base-T requirements. The 10/100Base-T cable is supplied by the end
user. Refer to Ethernet Connection Pin Assignments on page A-7 for pin
assignments and cable descriptions.
Ethernet LED Indicators
There are two unlabeled indicator LEDs on either side of the 10/100 Ethernet
jack. The LED on the left side of the jack pulses amber to indicate data
activity (either transmit or receive). The LED on the right side of the jack
lights green to indicate that the link layer is operational.
Serial Interfaces
The two SERIAL interfaces located on the rear of the WANsuite 5370 are
multi-protocol interfaces presented physically as DB-25 connections. The
protocols supported by these interfaces are RS-232, EIA-530, and V.35.
Optional cables that adapt the DB-25 interface to the 34-pin V.35 interface
are available.Their part numbers are listed under Optional Equipment on
page A-4. DB-25 to DB-25 cables are also available if your installation needs
require them. See Ordering Information on page A-4 for details. Pin
assignments for the Serial interface are listed in Appendix A, Specifications.
CAUTION: FCC rules require that interconnecting cables carrying high-speed
data be shielded appropriately to minimize radio frequency
interference.
