5. To check the status of the Ethernet line cards, inspect the SBx Status
LEDs on the control card. (If the chassis has two control 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 8 of the chassis
is operating normally when the SBx Status 8 LED is solid green. For
troubleshooting suggestions, refer to “Ethernet Line Cards” on
page 201.
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 203
and “Fiber Optic Transceivers” on page 207 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 23 on page 46. 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 205 for troubleshooting suggestions.
