1.6 Front Door
The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a critical,
major, or minor alarm is present anywhere on the ONS 15454 shelf. These LEDs must be visible so that
technicians can quickly determine if any alarms are present on the ONS 15454 shelf or the network. You
can use the LCD to further isolate alarms. The front door (Figure 1-18) provides access to the shelf
assembly, fiber-storage tray, fan-tray assembly, and LCD screen.

The ONS 15454 ANSI ships with a standard door but can also accommodate a deep door and extended
fiber clips (15454-DOOR-KIT) to provide additional room for cabling (Figure 1-19). The ONS 15454 ETSI
does not support the deep door.
