Overview

As a key network processing unit within the ZXR10 M6000-S series, the ZTE 240G control board is central to high-performance routing and switching for telecom and enterprise networks. This FAQ provides expert-level answers to the most pressing technical questions from network architects and engineers, covering pre-sales sizing, procurement compatibility, and post-sales configuration and troubleshooting.

Frequently Asked Questions

Q1: What is the precise uplink switching capacity of the ZTE 240G control board?

The ZTE 240G control board provides a bidirectional network processing capacity of 240 Gbps. This figure represents the maximum full-duplex throughput the board can handle, ensuring it can serve as a high-capacity aggregation or edge routing engine in service provider and enterprise core networks.

Q2: Which optical modules and interface cards (PIUs) are compatible with this board?

The board supports a wide range of Physical Interface Units (PIUs) via its two daughter card slots. Compatible modules include the RPZ-24G-SFP-S, RPZ-10XG-SFP+-S, RPZ-12XG-SFP+-S, and the RPZ-01CG-CFP2-S for high-speed 100G uplinks. This allows flexible deployment across 1G, 10G, 40G, and 100G network environments.

Q3: How does this board compare to its predecessor in terms of forwarding rate?

While the specific forwarding rate (Mpps) for the 240G board is not detailed, it is designed as a high-capacity network processing board for the M6000-S series, offering significantly higher bandwidth than previous generation Fast Ethernet or basic Gigabit modules. The 240G capacity ensures it can handle modern core routing tasks, and it is likely rated for line-rate forwarding on all enabled ports.

Q4: What is the basic CLI command to check the status of the control board?

The primary command to check the board's operational status is show card or show chassis. For detailed status on the specific PIU cards installed on the 240G board, use the command show interface brief to see the status of all ports. Use show environment to check power and temperature readings for the board.

Q5: What are the stacking interface options and limitations for this board?

The 240G control board itself does not have dedicated physical stacking ports. Stacking or virtual chassis functionality in the ZXR10 M6000-S series is typically achieved via the backplane or through fabric cards. The board connects to the System Routing Unit (SRU) or Main Processing Unit (MPU) via internal GE links to form the system's data plane.

Q6: How do I troubleshoot a power supply failover for this control board?

The board supports 2x -48V power supply inputs for redundancy. To troubleshoot, first check the system LEDs on the front panel. Confirm both power inputs are active and receiving voltage. Use the CLI command show power to view the status of each power supply module. If an input is faulty, the board can switch to the redundant feed, and the event will be logged in the system alarms.
