Figure 1-8 Cap Faceplate And Connections - Cisco ONS 15600 Reference Manual

Chapter 1 Shelf and Backplane Hardware
• Four visual alarm interfaces via a DB-15 connector that is surge-protected and EMI-filtered. The
visual alarm indication is provided by the TSC card and the signal is connected to the PDU where
LEDs indicate the alarm status and severity.
Environmental (external) alarms and controls (16 inputs and 16 outputs) via wire-wrap pins. The
•
interface is surge-protected and provides isolation by using an opto-isolator for alarm inputs and
relays for alarm outputs. By connecting to different wire-wrap pins on the CAP, the alarm outputs
can be configured for either normally open (NO) or normally closed (NC) operation. Alarms are
initiated by shorting these contacts. The alarm input interface provides a pair of positive and
negative wire-wrap pins.
The isolation and termination meet the intra-building lightning surge specified in Telcordia GR-1089.
The CAP has –48 VDC monitoring with I
information.

If the CAP fails, the node raises an EQPT alarm. You can replace the CAP on an in-service system
without affecting traffic. To replace a CAP, refer to the Cisco ONS 15600 Troubleshooting Guide.
Always replace the CAP during a maintenance window.
