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 FunctionBoard That Cannot Be SubstitutedCondition
N1SL16AN2SL16A/N3SL16AThe TCM function is enabled for the N2SL16A/N3SL16A.
N1SL64N2SL64The TCM function is enabled or AU-3 services are configured for the N2SL64.
N1SLQ16N2SLQ16The TCM function is enabled or AU-3 services are configured for the N2SLQ16.

N4SL64N2SL64The TCM function is enabled or AU-3 services are configured for the N2SL64.
N2EFS0/N4EFS0N1EFS0The 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.
N2EFS4N1EFS4If 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.
N4EFS0N2EFS0If 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.
N2EGS2N1EGS2The N1EGS2 is configured with QoS functions.
N1BPAN2BPAThe ALS function is required but not enabled on the line board.
N2BPAN1BPAThe 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 [email protected] for more info.
