Caution
You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the TXP_MR_2.5G
and TXPP_MR_2.5G cards in a loopback on the trunk port. Do not use direct fiber loopbacks
with the TXP_MR_2.5G and TXPP_MR_2.5G cards. Using direct fiber loopbacks causes
irreparable damage to the TXP_MR_2.5G and TXPP_MR_2.5G cards.
