Appendix A Hardware Specifications
You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_2.5G_10E_L card in
Caution
a loopback on the trunk port. Do not use direct fiber loopbacks with the MXP_2.5G_10E_L card. Using
direct fiber loopbacks causes irreparable damage to the card.
