LEDs

Status LED, one tricolor:

• Off—PIC is offline and safe to remove from the router.
• Green—PIC is operating normally.
• Yellow—PIC is initializing.
• Red—PIC has an error or failure.

Port LEDs, one pair for each port:

• Link LED

  • Off—Port is not enabled.
  • Green—Port is online with no alarms or failures.
  • Red—The router has detected a failure with alarms.

• Act LED

  • Green flashing—Port is sending or receiving packets.
  • Off—No packet activity detected on the port.

Caution: A T640 router with the following configurations and operating conditions can accommodate a maximum of 8 10-Gigabit Ethernet LAN/WAN with SFP+ PICs:

• One or two AC power supplies.
• Two DC power supplies in load-sharing mode with an input voltage between –43 VDC and –72 VDC.
• One DC power supply with an input voltage between –43 VDC and –72 VDC.

However, a router with only one DC power supply with an input voltage between –40 VDC and –43 VDC might not be able to support the maximum number of 10-Gigabit Ethernet LAN/WAN with SFP+ PICs. For more information, see technical bulletin PSN-2010-03-695.
