  • Page 9 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 Procedure Guide. Always replace the CAP during a maintenance window.
  • Page 10: Alarm, Timing, Lan, And Craft Pin Connections

    The ONS 15600 has a backplane pin field located at the bottom rear of the shelf that is part of the CAP/CAP2. The CAP/CAP2 provides 0.045 square inch (0.290 square centimeter) wire-wrap pins for enabling alarm inputs and outputs and timing input and output.
  • Page 11 The PDU Alarm connection controls the visual alarm indicators on the front of the PDU. You can also activate the alarm cutoff (ACO) function by pressing the ACO button on the TSC card faceplate. The ACO function extinguishes all audible alarm indications, but the alarm is still raised in Cisco Transport Controller (CTC).
  • Page 12 1.7.3 LAN Installation Use a straight-through LAN cable with the LAN port on the CAP or CAP2 to connect the ONS 15600 to a hub, switch, or a LAN modem for remote access to the node. Use a crossover cable when connecting the CAP or CAP2 to a workstation.
  • Page 13: Power Distribution Unit

    The PDU consists of a mounting chassis, A- and B-side power modules, an alarm module, and a rear I/O unit. The ONS 15600 PDU has LEDs that alert you to Critical, Major, Minor, and remote alarms on the node. Each module can support three 100A input power feeds, 48 VDC power load (based on a fully loaded ONS 15600 shelf).

The fan-tray assembly has three removable drawers that hold two fans each and fan-control circuitry for the ONS 15600 (Figure 1-12).
  • Page 15 Figure 1-12 Fan-Tray Assembly 1.10.1 Air Filter The ONS 15600 contains a reusable air filter that is made of an open-cell polyurethane foam that is flame retardant and fungi resistant. The air filter is located above the three fan trays (Figure 1-13).
  • Page 16 CTC software will shut down one of the single shelf cross-connect (SSXC) cards. The ONS 15600 requires at least one working fan in each of the three fan trays. When a single fan in a Caution tray fails, Cisco recommends replacing the tray with a fully working tray as soon as possible.
