Dear List, I have very odd problem with one 1000 BASE-SX PIC with an old m7i. Here is the Hardware inventory: Item Version Part number Serial number Description Chassis 36390 M7i Midplane REV 04 710-008761 XXXX M7i Midplane Power Supply 0 Rev 05 740-008537 XXXX AC Power Supply Routing Engine REV 11 740-009459 XXXX RE-5.0 CFEB REV 04 750-010463 XXXX Internet Processor II FPC 0 E-FPC PIC 0 REV 10 750-003163 XXXX 1x G/E, 1000 BASE-SX PIC 2 REV 10 750-003163 XXXX 1x G/E, 1000 BASE-SX PIC 3 REV 06 750-007641 XXXX 1x G/E IQ, 1000 BASE Xcvr 0 NON-JNPR XXXXXXXXXX SFP-LX FPC 1 E-FPC PIC 2 BUILTIN BUILTIN 1x Tunnel PIC 3 REV 07 750-009099 XXXXX 1x G/E, 1000 BASE Xcvr 0 REV 01 740-013111 XXXXX SFP-T Fan Tray Rear Fan Tray
2) If in the above configuration, instead of PIC 3, FPC0, I put this PIC: PIC 3 REV 01 750-005091 XXXXX 1x G/E, 1000 BASE-SX I'm starting to experience very strange PIC problems, manifesting in: 2.1) Input Errors 2.2) Carrier Transitions (happening quickly) 2.3) Reduced performance in terms of bandwidth (500mbps total via the PIC, but the Number of Packets/s almost inline with the normal packet load) If I put back the above IQ PIC back, everything goes back to normal. 3) The Same Faulty PIC 3 REV 01 750-005091 XXXXX 1x G/E, 1000 BASE-SX, if moved around the slots, of the same above chassis, doesn't make a change - i.e. again the same problems. 4) The Same Faulty PIC 3 REV 01 750-005091 XXXXX 1x G/E, 1000 BASE-SX, if put in another m7i chassis, but left alone on the FPC - works like a charm, no errors, no carrier drops, no problems. Any ideas, what could be the problem? Thank you, Zvezdelin Vladov _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
