SwitchBlade x3106 Chassis Switch and AT-SBx31CFC960 Card Installation Guide
5. To check the status of the Ethernet line cards, inspect the SBx Status
LEDs on the controller card. (If the chassis has two controller cards,
you may use the LEDs on either the active or inactive card.) A line card
is operating normally when it corresponding LED is solid green. The
LED flashes green as the card initializes its management software. If
an LED is flashing green after two minutes, the corresponding line card
may have a problem. For example, the line card in slot 2 of the chassis
is operating normally when the SBx Status 2 LED is solid green. (The
AT-SBx3106 Chassis does not use SBx Status LEDs 6 to 11.) For
troubleshooting suggestions, refer to "Ethernet Line Cards" on
page 232.
6. To check the status of the links of the individual ports on the line cards,
inspect the L/A LEDs on the cards. The LEDs should be solid or
flashing green on ports that are connected to active network devices. If
there is a problem with a link, refer to "Twisted Pair Ports" on page 234
and "Fiber Optic Transceivers" on page 238 for troubleshooting
suggestions.
7. To check the status of PoE on the ports of the AT-SBx31GP24 Line
Card, use the PoE LEDs, shown in Figure 17 on page 39 and
described in Table 8 on page 39. The LEDs are solid green when ports
are delivering power to powered devices on your network. If there is a
problem, refer to "Power Over Ethernet" on page 236 for
troubleshooting suggestions.
8. If the LEDs indicate that the chassis components are operating
normally, you should perform the procedure in the next section to
establish a management session with the chassis and confirm the
hardware operations with the command line commands.
