IE-3000 Transceiver issue

[eamon.byrne]

Hi All,

I'm receiving this error message when trying to connect a cisco IE-3000-4TC switch IOS 15.2(3)EA to a cisco WS-C3850-48T-E stack switch ver 16.3.3 using GBIC's GLC-BX40-UI. I'm using SMF LC-to-LC.

I've tried to manipulate the fibre but the value's still stay the same.

%PHY-5-TRANSCEIVERINSERTED: Slot=1 Port=1: Transceiver has been inserted
.May 22 10:14:09: %SFF8472-5-THRESHOLD_VIOLATION: Gi1/1: Rx power low alarm; Operating value: -40.0 dBm, Threshold value: -28.8 dBm.

Any help greatly appreciated.

Thanks.

According the the transceiver data sheet,  a GLC-BX40-D-I (or GLC-BX40-DA-I) device connects to a GLC-BX40-U-I device.  Thus, you cannot connect use a GLC-BX40-U-I SFP on both sides of a fiber link.
