2.3.3 Relay Connections
The 9119 Media Converter features dry-contact alarm relays. These contacts are available via a removable terminal block
on the rear panel (see Figure 2-4).
The relays monitor each interface's Link Integrity, plus the Remote (Fiber) Fault status. In addition, the UTP Interface
relay is configured such that power failure will result in the same state as a status alarm (i.e., loss of link).
The description of the alarm contacts is the following:
NO Normally Open. This means open during Normal, non-fault operation; closed during a fault condition.
NC Normally Closed. This means closed during Normal, non-fault operation; open during a fault condition.
C Common. Common terminal between alarm contacts.
2.4 Installing the 9119 Media Converter
The 9119 Media Converter is an easy to install device and can be installed in the Canoga Perkins Model 9101 LAN Chassis,
attached to vertical or horizontal surfaces, or used in a table top configuration. As with all electronic devices, adequate air
flow should be provided around the unit since some heat is generated.
The 9119 should not be placed on top of another device that also generates heat. The cumulative heat can cause the internal
temperature of the 9119 to exceed its design specifications which could potentially lead to inconsistent operation.
