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/CAP2, 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 specification in Telcordia
GR-1089. The CAP and CAP2 have –48 VDC monitoring with an I
to store the CAP/CAP2 revision information.

If the CAP/CAP2 fails, the node raises an EQPT alarm. You can replace the CAP/CAP2 on an in-service
node without affecting traffic. To replace a CAP, refer to the Cisco ONS 15600 SDH Procedure Guide.
Always replace the CAP during a maintenance window.
