SwitchBlade x8112 Chassis Switch and AT-SBx81CFC400 Card Installation Guide
prevents them from completing the initialization process. Power off the
chassis and replace the cards.
5. To check the status of the Ethernet line cards, inspect the SBx
Linecard Status LEDs on the controller card. (If the chassis has two
controller cards, you may use the LEDs on either card.) A line card is
operating normally when its 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 and cannot complete the initialization process.
For example, the line card in slot 8 of the chassis is operating normally
when the SBx Linecard Status, number 8 LED is solid green. For
troubleshooting suggestions, refer to "Ethernet Line Cards" on
page 222.
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 224
and "Fiber Optic or Twisted Pair Transceivers" on page 228 for
troubleshooting suggestions.
7. To check the status of PoE on the ports of the AT-SBx81GP24 Line
Card, use the PoE LEDs, shown in Figure 18 on page 43. 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 226 for troubleshooting suggestions.
