Q: Can I use new version board to replace old version ones?

A: Yes, most of OSN3500 service board, you can use newer verison to replace old ones, here listed some ordinary substitution boards below, or you can contact technical sales team to confirm the board substitution relation.

Substitute Board To-Be-Substituted Board Substitute Board To-Be-Substituted Board
N2PL3 N1PL3 N3SL16 N1SL16
N2PQ1B N1PQ1B N4SL64 N1SL64/N2SL64

Q: Is there any restrictions for board substitution?

A: Yes, there list some restrictions when board substitution below, or you can contact technical sales team to confirm the board substitution relation.

Board That Supports the Board Version Replacement Function Board That Cannot Be Substituted Condition
N1SL16A N2SL16A/N3SL16A The TCM function is enabled for the N2SL16A/N3SL16A.
N1SL64 N2SL64 The TCM function is enabled or AU-3 services are configured for the N2SL64.
N1SLQ16 N2SLQ16 The TCM function is enabled or AU-3 services are configured for the N2SLQ16.
N3SL16 N2SL16 The TCM function is enabled or AU-3 services are configured for the N2SL16.
N3SL16A N2SL16A AU-3 services are configured for the N2SL16A.
N3SLO1 N2SLO1 AU-3 services are configured for the N2SLO1.
N4SL64 N2SL64 The TCM function is enabled or AU-3 services are configured for the N2SL64.
N2EFS0/N4EFS0 N1EFS0 The N1EFS0 is configured with QoS functions.If an N4EFS0/N2EFS0 is configured as an N1EFS0 and the simulation package loading method is used, the board software of the N1EFS0 is loaded. As a result, a cold reset is performed on the board and the board version replacement function becomes ineffective. Therefore, an N4EFS0/N2EFS0 must not be configured as an N1EFS0.
N2EFS4 N1EFS4 If an N2EFS4 is configured as an N1EFS4 and the simulation package loading method is used, the board software of the N1EFS4 is loaded. As a result, a cold reset is performed on the board and the board version replacement function becomes ineffective. Therefore, an N2EFS4 must not be configured as an N1EFS4.
N4EFS0 N2EFS0 If an N4EFS0 is configured as an N2EFS0 and the simulation package loading method is used, the board software of the N2EFS0 is loaded. As a result, a cold reset is performed on the board and the board version replacement function becomes ineffective. Therefore, an N4EFS0 must not be configured as an N2EFS0.
N2EGS2 N1EGS2 The N1EGS2 is configured with QoS functions.
N1BPA N2BPA The ALS function is required but not enabled on the line board.
N2BPA N1BPA The ALS function is required but not enabled on the N2BPA.

Q: What is P1L1-2D2 module, the name is not ordinary

A: P1L1-2D2 is STM-64 optical module in N4SL64 board, distance is 80KM; same function like LS64.2 in N1SL64

Q: Does V64.2B module can transit over 120km?

A: Yes, but V64.2B must work together with BPA board and DCU board.

Q: What is different with Huawei OSN3500 and OSN1500

A: OSN3500 is STM64 level MSTP, while OSN1500 is STM16 level

Q: Do you have U2000 NMS and U2000 NMS License If I buy OSN 3500 from you?

A: Yes, we can share U2000 software package for our customer free of charge and provide our customer U2000 license for test purpose, not for commercial use.

Q: Does OSN3500 have AC power supply?

A: No, OSN3500 power interface unit PIU is DC -48V input only, if you need a AC/DC power converter, ETP4890 is recommended, please contact with sales team.

Q: Except EAS2, does OSN3500 have other board for 10GE service?

A: Yes, besides EAS2 boards, also have PEX1 and PEX2; different is EAS2 for MSTP version, PEX1/PEX2 for Hybrid MSTP version. Contact for more info.

    United Kingdom (UK)

    This is my second purchase from, I pay attention to the quality of service, so I chose again

  3. Hrant

    Does OSN 3500 support management of the UPM system?

  4. Mohammad

    I was trying to configure this MUX and found one issue on the STM4 card. Only 2 ports out 4 is recognised, we swapped SFP etc but only port 1 and 2 are active 3 and 4 are not.

  5. Gustavo

    Quick and professional technical support when i have question about configuration, but communicating with their engineer is a little difficult.

  6. Higley

    Everything is ok, but the delivery
