EC9535 GSC Node Bus Converter • User’s Guide 1
1. Introduction
The EC9535 GSC Node Bus Converter is a communications protocol converter designed to enable
Miranda’s NV8288, NV8288-Plus or NV8500 Family (NV8144, NV8280 or NV8576) routers to
communicate with a SMS7000 system controller. A system controller is a hardware system that
runs a router control system application. The router control system sends commands to a router’s
control cards (i.e., circuit boards), telling them what switching tasks to perform.
The SMS7000 system controller requires a GSC Node Bus connection in order to connect and com-
municate with the router. All of Miranda’s routers have a GSC Node Bus connection, except for the
NV8288, NV8288-Plus or NV8500 Family. The EC9535 solves this problem by providing an inter-
face with a GSC Node Bus. The SMS7000 connects to the EC9535, which in turn, is connected to
the NV8288, NV8288-Plus or NV8500 Family router.
Product Overview
The EC9535 GSC Node Bus Converter is used as an interface between a SMS7000 system control-
ler and a specific Miranda router. Unlike a router, the EC9535 does not actively manage signals.
Instead the EC9535 provides a GSC Node Bus to serial interface that enables a SMS7000 system
controller to communicate with Miranda routers that feature only serial system controller connec-
tions. In addition, the EC9535 provides high reliability through redundant power supplies and
redundant control cards, as well as deterministic communications processing.
Mounting
The EC9535 GSC Node Bus Converter mounts in a rack with minimum dimensions of 2RU high
(3.47 inches, 88.1 mm), and 16.0 inches (406 mm) deep. When placing the rack in your facility, be
sure to leave enough space for air flow through the front and rear of the EC9535 and within easy
access of an AC power source. For mounting instructions, see
Rack Mount on page 10.
Fuses
The EC9535 GSC Node Bus Converter has no user-serviceable fuses.
Cooling
The EC9535 GSC Node Bus Converter has one fan providing forced air cooling. The fan is
accessed from the front of the frame. The fan draws cooling air from the front of the frame, through
the door, and exhausts it through a grill in the rear door. The EC9535 must have the door correctly
installed and closed for proper airflow through the chassis.
Caution
If airflow is impeded, overheating may occur.
