The craft interface shows you status and troubleshooting information at a glance and lets you perform many system control functions. It is hot-insertable and hot-removable. The craft interface is located on the front of the services gateway above the card cage and contains the following components:

Note: At least one SCB must be installed in the services gateway for the craft interface to obtain power. |
Two large alarm LEDs are located at the upper right of the craft interface (see Figure 16). The circular red LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.
A condition that causes an LED to light also activates the corresponding alarm relay contact on the craft interface, as described in Alarm Relay Contacts.
To deactivate the red and yellow alarms, press the button labeled ACO/LT (for “alarm cutoff/lamp test”), which is located to the right of the alarm LEDs. Deactivating an alarm turns off both LEDs and deactivates the device attached to the corresponding alarm relay contact on the craft interface.
Table 13 describes the alarm LEDs and alarm cutoff button in more detail.

The host subsystem has three LEDs, located on the upper left of the craft interface, that indicate its status. The LEDs labeled RE0 show the status of the Routing Engine and SCB in slot 0 . The LEDs labeled RE1 show the status of the Routing Engine and SCB in slot 1. Table 14 describes the functions of the host subsystem LEDs.

Each power supply has two LEDs on the craft interface that indicate its status. The LEDs, labeled 0 through 3, are located on the upper left of the craft interface next to the PEM label. Table 15 describes the functions of the power supply LEDs on the craft interface.

The craft interface has a row of Online buttons along its lower edge. Each button corresponds to one slot in the card cage.
In the current release, the Online buttons are only supported for slots containing I/O cards (IOCs).
The craft interface has two alarm relay contacts for connecting the device to external alarm devices (see Figure 17). Whenever a system condition triggers either the red or yellow alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay contacts are located on the upper right of the craft interface.
