Product Description ES1D2SRUE000-S7700/S7712 Main Control Unit E Version Mapping Table 1 Switch chassis and software versions matching the card Card Name S7700 Chassis ES1D2SRUE000 S7703 chassis: not supported S7706 and S7712 chassis: supported in V200R010C00 and later versions Introduction The ES1D2SRUE000 can be installed in: Slots 07 and 08 in an S7706 chassis. Slots 13 and 14 in an S7712 chassis. Figure 1 Appearance of ES1D2SRUE000 Functions and Features An SRU integrates control and switching functions. It provides the control plane, management plane, and data plane for the system, which are described as follows: The control plane is responsible for protocol processing, service processing, route computing, forwarding control, service scheduling, traffic statistics collection, and system security. The management plane is responsible for system status monitoring, environment monitoring, log and alarm processing, system software loading, and system upgrades. The data plane provides high-speed, non-blocking data channels to implement service switching between service modules. An SRU consists of the following modules: Control module: control and management plane for the RU and the entire system. It implements protocol processing, route computing, forwarding control, system management, and system security. Switching module: data plane of the system. It provides high-speed service channels for data switching. Device management and monitoring module: provides the controller area network bus (CAN Bus) module to monitor the RU and LPU CAN Bus modules. Power supply module: provides power for Switching and Routing Units (SRUs) and Flexible Service Units (SFUs). Table 2 Functions and features of the ES1D2SRUE000 Function and Feature Description Basic function System control and management unit for the S7712 and S7706, integrating the control unit, switching unit, and system maintenance unit. Distributed forwarding Performs concurrent data forwarding using a distributed data plane. Memory 4 GB Flash 64 MB eUSB card 2 GB By default, the system configuration data, startup files, system software package, and system logs are saved to the eUSB card. CSS The ES1D2SRUE000 can have ES1D2VS04000 installed to provide the CSS service. OAM The ES1D2SRUE000 can have ES0D00FSUA00 installed to provide enhanced services such as OAM and BFD. 802.1ag: identifies, detects, and sends continuity check (CC) packets. Multiprotocol Label Switching (MPLS OAM): identifies, detects, and sends MPLS OAM packets. OAM UNCFG_MEP. Redundancy backup Supported MPUs are mandatory for switches. You can configure one or two MPUs for each switch. The MPU can be installed in either MPU slot of a switch. An MPU consists of the control plane, management plane, and data forwarding plane. When two MPUs are installed, the two MPUs work in hot standby mode on the control and management planes and work in load balancing mode on the data forwarding plane. MPUs monitor each other. When the active MPU is faulty, the standby MPU is automatically switched to be the active MPU to ensure service continuity. Hot swap Supported Before removing the active ES1D2SRUE000 card, perform an active/standby switchover. Usage Constraints NOTICE: Main control units of different models cannot be used in the same chassis. The fans in a switch work in intelligent speed adjustment mode after a switchover between the active and standby main control boards in the switch. If the fans run at a specified speed before a switchover, run the set fan-speed command after the switchover to set the fan speed again. Indicators and Ports Figure 2 Indicators and buttons on the ES1D2SRUE000 panel Table 3 Indicators and buttons on the ES1D2SRUE000 panel Number Indicator/Button Color Description 1 LINK indicator of a GE optical port NOTE: These indicators are reserved. 2 ACT indicator of a GE optical port 3 USB indicator Green Steady on: USB-based deployment of the card has been completed. Fast blinking: The card is reading data from a USB flash drive. Yellow Steady on: The card has finished reading data from the USB flash drive. You can remove the USB flash drive now. Red Steady on: The card fails to connect to the network management system (NMS) or fails to register with the NMS. Fast blinking: An error has occurred when the card is executing the configuration file or reading data from a USB flash drive. - Off: No USB flash drive is connected to the card, the USB port on the card is damaged, or the indicator is damaged. 4 ACT indicator of the ETH port Yellow Blinking: The port is transmitting and receiving data. 5 LINK indicator of the ETH port Green Steady on: A link has been established on the port. 6 RST button - Press this button to reset the card. NOTE: Resetting a card will cause service interruption, therefore, exercise caution when deciding to press the RST button. 7 ACT: active/standby status indicator Green Steady on: The card is the active main control unit of the switch. Off: The card is the standby main control unit of the switch. NOTE: When two chassis set up a cluster using service ports: Steady on: The card is the active main control unit of the cluster. Blinking: The card is the hot standby main control unit of the cluster. Off: The card is the cold standby main control unit of the cluster. 8 RUN/ALM: running status indicator Green Steady on: The card has been powered on, but the software is not running. Slow blinking: The card software is running properly. Fast blinking: The card software is starting. Red Steady on: The card has failed, and the fault requires manual intervention. Yellow Steady on: The card is powered off. Figure 3 Ports on the ES1D2SRUE000 panel 1 One subcard slot. A subcard for the main control unit can be installed in this slot. 2 Two GE ports (reserved). 3 One USB port. It is used to load software from a USB flash drive. 4 One console port. It can connect to a configuration terminal to implement onsite configuration of the S7700. 5 One ETH management port (10/100BASE-TX auto-sensing). It can connect to a network port of a configuration terminal or network management workstation to set up a local or remote configuration environment. ETH management port The ETH management port of a switch connects the switch to a configuration terminal or network management workstation to set up a local or remote configuration environment. The port must be used with an Ethernet cable. Table 4 describes the attributes of the ETH management port.
