S12710 Clustering Using CSS Cards
Context
For details about cluster configuration precautions, see "CSS Support and Version Requirements" in the Configuration Guide - Device Management.
- When installing a copper cable, optical module, or optical fiber, you can determine that it has been installed properly after hearing a click.
- When removing a copper cable, optical module, or optical fiber, push its connector or handle slightly and then pull it out.
- Ensure that the bend radius of the copper cables or optical fibers is greater than the minimum bend rand required. For more information, see the Hardware Description.
Tools and Accessories
- ESD wrist strap or ESD gloves
- Phillips screwdriver
- Diagonal pliers
- Cable ties
- Labels
Procedure
- Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that the ESD wrist strap is in a close contact with your wrist, and insert the other end in the ESD jack of a cabinet/rack.
- Install the MPU and SFU, as shown in Installing a Card.
- Attach number labels on both ends of the cluster cables.
- Connect the stack ports with cluster cables.
- 4*10GE ports (The following example uses chassis with only one MPU and one SFU)
- 40GE ports (The following example uses chassis with only one MPU and one SFU)
- Follow these rules when connecting S12710 integrated CSS cards:
- On the S12710, the local and peer chassis can be connected using either MPUs or SFUs or both MPUs and SFUs. MPUs or SFUs in one chassis can only be connected to the same type of cards (MPUs or SFUs) in the other chassis.
- MPU-integrated and SFU-integrated CSS cards have two types of ports: 4*10GE ports and 40GE port. 10GE ports with the same port number must be connected, as shown in the preceding figure. For example, port 1 in blue on the left chassis must be connected to port 1 in blue on the right chassis.
- The two chassis can set up a CSS as long as they are connected by one cluster cable. To ensure reliability, it is recommended that each MPU or SFU be connected using at least two cluster cables.
- To support 1+N MPU backup, ensure that SFUs are connected using cluster cables.
- To connect the stack ports with optical fibers, install optical modules on the stack ports, and then connect optical fibers to the optical modules.
- To connect the stack ports with copper cables, directly connect the copper cables to the stack ports.
- Arrange the cables, route the cables through cable management frames, and bundle them with cable ties.
Keep the cable ties used to bundle cables on the same horizontal plane as the SFP+ or QSFP+ ports to reduce the impact of gravity on these ports.
- Check the LINK indicator on the service cards. If the indicator is steady green, the ports are correctly connected.
To power on the switches, ensure that power cables and ground cables are correctly connected and then switch on the external power modules and built-in power modules in turn.
