Introduction
The ES0D00MCUA00 can be installed in slots 04 and 05 in an S7703 or S7703 PoE chassis.
Functions
The ES0D00MCUA00 is the main control unit of the S7703 and S7703 PoE. It integrates the main control unit, clock unit, and system maintenance unit, and provides the following functions:
- Provides channels for out-of-band communication between cards.
- Monitors system operation. The ES0D00MCUA00 periodically collects operation data of different units. According to running status of the units, the ES0D00MCUA00 generates control information to check card presence, control fabric running status, perform port switching, reset the forwarding engine, and increase the fan speed.
- Functions as the proxy of the network management software: The ES0D00MCUA00 manages and maintains the switch through management ports (console port and Ethernet port).
- Stores configuration data, startup files, accounting information, upgrade software, and system logs. The ES0D00MCUA00 provides a CF card to store data files as a mass storage device.

CF card |
512 MB By default, the system configuration data, startup files, system software package, and system logs are saved to the CF card. |
Redundancy backup |
Supported Main control board is mandatory for switches. Each switch must be configured with one or two main control boards. When one main control board is configured for a switch, the main control board can be installed in either main control board slot of the switch. When two main control boards are configured, the two main control boards work in hot standby mode to improve reliability of the switch. The active and standby main control boards monitor the status of each other. If the active main control board fails, the standby main control board automatically becomes active to ensure uninterrupted services. |
Hot swapping |
Supported Before removing the active ES0D00MCUA00 card, perform an active/standby switchover. |
Usage Constraints
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 units 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.

ACT: active/standby status indicator |
Green |
Steady on: The card is the active MCU. Off: The card is the standby MCU. |
3 |
RUN/ALM: running status indicator |
Green |
Steady on: The card is powered on. If the indicator is steady green for no more than 30 seconds, the CPU is being started. If the indicator is steady green for more than 30 seconds, 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. |

Steady on: The card is powered off. |
1 |
One RS485 port (reserved). |
2 |
One MON port (reserved). |
3 |
One console management port. A configuration terminal can connect to this port to implement onsite configuration of the S7700. |
4 |
One ETH management port (10/100BASE-TX auto-sensing). A configuration terminal or network management workstation can connect to this port to set up a local or remote configuration environment. |
ETH management port
A switch can connect to a configuration terminal or network management workstation through the ETH management port for onsite or remote configuration. The port must use a Ethernet Cable. Table 7-70 describes the attributes of an ETH management port.
