Outstanding Issues with the T1600 Router

 

This topic lists outstanding hardware issues with the T1600 Core Router.

  • To support the 10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+ (model number PD-5-10XGE-SFPP) in the T1600-FPC4-ES (part number 710-013037), REV 13 and later is required.

    T1600-FPC4-ES (part number 710-013037), REV 12 and earlier does not support the 10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+ (model number PD-5-10XGE-SFPP).

  • When the C8000-RE Routing Engine is installed, the LEDs for the ETHERNET ports on the connector interface panel (CIP) have the following issues:

    • Model number RE-DUO-C1800-8G (part number 740-026941 Rev 7)—The activity LEDs, labeled ACT0 and ACT1, for the ETHERNET ports on the connector interface panel (CIP) are always steadily green, even when no cables are connected to the ports.

      For RE-DUO-C1800-8G (part number 740-026941 Rev 8) and above, the CIP LED behavior is as described in the T1600 Core Router Hardware Guide.

    • Model numbers RE-DUO-C1800-8G and RE-DUO-C1800-16G—The LEDs labeled GRN = 100M and YEL= 10M is always yellow, but the speed is always a 100-Mbps connection.

  • After powering on or off a power supply, wait at least 60 seconds before turning it back off or on again.

  • After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply, show chassis commands, and messages on the craft interface LCD —to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

  • The external clock inputs on the SONET Clock Generators (SCGs) with DB-9 ports (model number SCG-T) are not supported.

  • The external clock inputs on the SONET Clock Generators (SCGs) with RJ-45 ports (model number SCG-T-EC) are supported for JUNOS OS Release 10.4 and later.
