SBx STATUS
LEDs
The SBx STATUS LEDs display general status information about the
Ethernet line cards and controller cards, as described in Table 13 on
page 56. There are twelve LEDs, number 0 to 11. However, only LEDs 0
to 5 are active because the AT-SBx3106 Chassis has only six slots. LEDs
6 to 11 are not used. If the chassis has two controller cards, the SBx
Status LEDs on both cards are active.
