Q: What are the types of the Main Control Boards of the S7700 and S9700?


The main control boards of the S7700 include ES0D00MCUA00, ES0D00SRUA00, ES0D00SRUB00,and ES1D2SRUH000. The details are as follows:

  • The ES0D00MCUA00 is installed on the S7703.

  • The ES0D00SRUA00, ES0D00SRUB00 and ES1D2SRUH000 are installed on the S7706 and S7712.

The main control boards of the S9700 include EH1D2MCUAC00, EH1D2SRUDC00, EH1D2SRUDC01, and EH1D2SRUC000. The details are as follows:

  • The EH1D2MCUAC00 is installed on the S9703.

  • The EH1D2SRUDC00, EH1D2SRUDC01 and EH1D2SRUC000 are installed on the S9706 and S9712.

Q: Are the Main Control Boards and LPUs hot swappable?

A: All the main control boards and LPUs of the S7700&S9700 are hot swappable. In addition, the fans and power supplies are hot swappable.

The ES0D00FSUA00, ES02VSTSA, EH1D2VS08000 and ES1D2VS04000 are not hot swappable.

Q: Does the S7700 and S9700 support hot backup?

A: The S7700&S9700 supports hot backup. When the master main control board fails, the S7700&S9700 automatically switches services to the slave board without interrupting the services. The software versions of the master board and slave board must be the same. 

Q: Does the S7700 and S9700 support the optical modules of other vendors?

A: Use optical modules certified for Huawei switches. Non-certified optical modules cannot ensure transmission reliability and may affect service stability on the switch. We will not responsible for any problem caused by non-certified optical modules and will not fix such problems.

Q: Does the GE optical LPU of the S7700 and S9700 support 100M optical module?

A: Yes, the S7700&S9700's GE optical LPU supports both 100M optical modules and 1000M optical modules.

When a 100M optical module is used, you must run the speed 100 command on the interface to set the interface rate to 100 Mbit/s.

When using a GE optical module, an interface works at 1000 Mbit/s by default. If auto-negotiation is enabled on the interface, the interface speed cannot be set to 100 Mbit/s. If auto-negotiation is disabled, you can run the speed 100 command to set the interface speed to 100 Mbit/s.The 100M optical interface can only use the 100M optical module, and the default interface rate is 100M.

When two optical interfaces are interconnected, they must use the same type of optical module.

Q: Does the S7700 and S9700 support the AC power supply and DC power supply?

A: AC and DC power modules or power modules of different power values cannot be installed simultaneously in the same type of power slots (system or PoE). In versions earlier than V200R006C00, the PoE slots of a switch allow only AC power modules. To use the PoE function on a switch, use AC power modules as the system power modules. In V200R006C00 and later versions, the PoE slots allow both AC and DC power modules.

Q: Are the power modules of S7700 and S9700 hot swappable?

A: Power modules of the S7700&S9700 are hot swappable. Before removing a power module, ensure that the chassis can work normally without the power module. When removing or installing a power module, take electrical protective measures to avoid electric shock.

Q: What are the functions of the CF card of the S7700 and S9700?

A: The S7700&S9700 series switches support standard CF cards. The default capacity of a CF card is 512 MB, expandable to 1 GB or 2 GB. The CF card is used to store system files, configuration files, paf, License, and log files.

The S7700&S9700 series switches can start by using the startup file in the CF card. In this case, the system software package is stored on the CF card. It is required to specify the system software package on the CF card as the boot file. On the S7700&S9700 series switches, logs can be stored on the CF cards.

Q: Is the CF card hot swappable?

A: The CF cards are not hot swappable.

Q: Can GE optical modules and GE electrical modules be installed on the same interface board of the S7700 and S9700?

A: GE optical modules and GE electrical modules can be installed on the same 1000M optical interface board of the S7700&S9700, but you must configure the O/E converter on the 1000M optical interface board.

The 1000M optical interface board of the S7700&S9700 can use only the Huawei certified converter. When O/E converters of other vendors are installed on interfaces of the S7700&S9700, the interfaces still work as optical interfaces.

Q: What are the differences between the E series, F series, and S series LPUs of the S7700 and S9700?

A: S7700&S9700 LPUs are classified into three series: E series, F series, and S series.

The E series is the enhanced series, and supports Multiprotocol Label Switching (MPLS) and extension of routing, ACL, and MAC address entries. The E series consists of the EA, EC, ED, and EE LPUs.

The F series is the ordinary series, and supports MPLS but not extension of MAC address entries. The F series consists of the FA and FC LPUs.

The S series is the standard series and does not support extension of MAC address entries. The S series consists of the SA and SC LPUs. The SA LPUs do not support MPLS, whereas the SC LPUs support MPLS.


Q: Can I get technical support from if we purchase LS-S7703 from you?

A: Yes, has experienced technical team on Huawei switches, however, you may need to purchase technical support service from us as by default we only provide one year hardware warranty.

Q: Can traffic be mirrored to an interfance on S7700 series switch?

A: Currently traffic mirroring can be configured for both inbound and outbound traffic. Traffic, however, must be mirrored to an observing interface.

Q: Does the S7700 series switch support inter-board mirroring?

A: Yes, the S7700 supports.

This function has a bug: If an outgoing packet on the mirrored interface is untagged, a tag is added to the packet when the packet is sent out through the observing port.

Q: Does S7700 series switch support netstream?

A: The V100R003 and later versions support NetStream.

Q: Does S7700 series switch support IGMPv3?

A: The S7700 series switches support only a simplified version of IGMPv3 in Layer 2 multicast application. In this version, either (*, G) entries or (S, G) entries will be generated for a multicast group. If (*, G) entries are generated, data of all sources is received. If (S, G) entries are generated, data of a specific source is received. If the specified group address is in the SSM group address range, only source-specific programs can be ordered.

Q: Does S7700 series switches support static RP?

A: On S7700 series switches, you can configure a maximum of 50 static RPs by running the static-rp command repeatedly in the public network instance PIM view or VPN instance PIM view. An ACL can be referenced by only one static RP. If no ACL is specified in the static-rp command, only one static RP can be created.

Q: Does S7700 series switches support static multicast routes?

A: The S7700 series switches support the igmp static-group command to configure static groups. In addition, they support static multicast routes configured through the ip rpf-route-static command.

Q: Does S7700 support the weighted load balancing mode?

A: The S7700 perform load balancing among equal-cost routes, but does not perform load balancing based on weights.
