Q: How many hardware version does TOX have?

A: TOX is available in two functional versions, namely, TN55 and TN56. The mapping between the board and equipment as below:

Board Initial Version General 8800 T64 Subrack Enhanced 8800 T64 Subrack General 8800 T32 Subrack Enhanced 8800 T32 Subrack 8800 T16 Subrack 8800 Universal Platform Subrack 6800 Subrack 3800 Chassis
TN55TOX V100R7C00 N Y Y Y Y N N N
TN56TOX V100R9C00SPC100 N Y Y Y Y N N N

Q: We check that Enhanced OSN8800 T32 subrack can support TN55TOX, but why it still cannot work normally on this subrack?

A: Please check your the cross-connect board type configured on your Enhanced OSN8800 T32:

1, For enhanced OSN 8800 T64 subrack, TOX must work with TNK2USXH and TNK2UXCT.

2, For enhanced or General OSN8800 T32 subrack, TOX must work with TN52UXCH or TN52UXCM.

3, For OSN 8800 T16 subrack, TOX must work with TN16UXCM.

  1. lorane

    We received the card with a test paper inside the box, good!

  2. Ramiro

    Perfect, we got 2pcs 8 port 10G instead of 1pca 10 ports 10G, for further extension; when TOX apply to enhanced OptiX OSN 8800 T32, I must use cross-connect board TN52UXCM?

  3. Norman

    Good quality products, priced very low, and delivered quickly.
