Hardware Information
Figure1 shows the logical structure of hardware modules in the router. Hardware modules of the router refer to the Service and Router Unit (SRU), power supply, fan, and card.
SRU
The SRU integrates the switching module and control module and provides the following functions:
- Processes protocol packets.
- Manages the system and monitors the system performance according to instructions of the user, and reports the device running status to the user.
- Monitors and maintains the switching module and control module.
Power Supply
The power supply powers the router. For details about power supply configurations for the router, see the Power Supplies section in the Hardware Description.
Fan Module
The fan module dissipates heat for the router. Cold air flows into the router from the left side and is exhausted from the right side, taking away heat generated by the router. This ensures that the router works in the operating temperature range.
For details about fan modules in different models, see "Heat dissipation" under Chassis in the Hardware Description.
Card
The router supports multiple types of service cards, these cards improve networking flexibility and meet customers' requirements for cost-effective and personalized solutions.
For details, see Cards in the Hardware Description.
