Item Code: 33485

$1,302.83pad



The Cisco 12016 or Cisco 12416 Internet Router alarm card has three primary functions: 1) provides a visual display of three severity levels of alarms (critical, major, and minor) detected by the system through the Mbus; 2) provides a connection to a site-wide external alarm system; 3) provides visual indicators of the status of the alarm card, clock and scheduler cards (CSCs), and the switch fabric cards (SFCs). The alarm card faceplate is equipped with three pairs of LEDs - labeled Critical, Major, and Minor - that are used to identify system-level alarm conditions detected through the MBus. The alarms can warn of an overtemperature condition on a component in one of the card cages, a blower failure in a blower module, an overcurrent condition in a power supply, or an out-of-tolerance voltage on one of the cards in one of the card cages. The LEDs are driven by MBus software, which sets the threshold levels for triggering the different stages of alarms. The route processor (RP) continuously polls the system for temperature, voltage, current, and blower speed values. If an over-threshold value is detected, the RP sets the appropriate alarm severity level on the alarm card, which lights one of the LED pairs and energizes the appropriate alarm card relays, activating any external audible or visual alarms wired to the alarm card. The RP also logs a message about the threshold violation on the system console.
