PTX12008 Switch Interface Board
Learn about the PTX12008 Switch Interface Board and its status LEDs.
Switch Interface Boards (SIBs) create the switch fabric for the PTX12008. SIBs are hot-removable and hot-insertable field-replaceable units (FRUs). The SIBs are not visible from the outside of the router chassis. You must remove the fan trays on the rear panel of the chassis to see the SIBs. You can install up to nine SIBs.
Each SIB has two LEDs labeled PWR and STAT. Table 1 describes the functions of these LEDs.

Fan Tray and SIB Status LEDs
Each fan tray has one LED labeled FAN TRAY that represent the status of the fans in the fan tray and three LEDs collectively labled SIB STATUS that represent the status of the Switch Interface Boards (SIBs) installed behind the fan tray. The LEDs are located in the top left corner of the fan tray.
1 — Fan status LED | 2 — SIB status LEDs (SIB 0 through SIB 2 for the fan tray on the left, SIB 3 through SIB 5 for the fan tray in the middle, and SIB 6 through SIB 8 for the fan tray on the right) |
