- When looking at the KCU105, we are connecting to the SFP connected farthest to the left
- The PGP card has an integrated SFP transceiver. However, the KCU105 does not. The SFP module that you plug in the KCU105 board needs to support "850nm" multi-mode fiber optics. We recommend using "SFP-10GSR-85" from Fiberstore.com.
- The fiber optic cable between the PGP card and the DEV board needs to support "850nm", multi-mode, OM2 (or OM3) and LC terminated on both sides.

KCU105 Board's LED[7:0]
| LED[7:0] | Status |
|---|---|
| LED[7] | SW5 External Reset Button (0x0=normal,0x1=reset) |
| LED[6] | Firmware Interface Reset (0x0=normal,0x1=reset) |
| LED[5] | PgpTx.LinkReady |
| LED[4] | PgpTx.PhyReady |
| LED[3] | PgpRx.RemLinkReady |
| LED[2] | PgpRx.LinkDown |
| LED[1] | PgpRx.LinkReady |
| LED[0] | PgpRx.PhyReady |
- If the fiber optics is disconnected, the state of the LEDs should be LED[7:0] = 0x31 (see image below)
- If the fiber optics is connected and PGP connect is good, the state of the LEDs should be LED[7:0] = 0x3B (see image below)
