Description
ES5D00ETPC00 overview
Huawei ES5D00ETPC00 Stack Rear Card.
Intelligent Stack (iStack) technology enables multiple stacking-capable devices to function as a logical device.
Before a stack is set up, each switch is an independent entity that has its own IP address and MAC address. You need to manage the switches separately. After a stack is set up, switches in the stack form a logical entity that can be managed and maintained using a single IP address. Stack technology improves forwarding performance and network reliability, and simplifies network management.
Switches can be connected as a stack using service ports or stack cards (ES5D00ETPC00).
The ES5D00ETPC00 stack card can be installed in a rear card slot of the switch models listed in Table 8-189.

Functions
| Function | Description |
|---|---|
| Basic function | Provides two 12 Gbit/s electrical ports for stacking. The 12 Gbit/s electrical ports on multiple switches are connected using PCIe cables to set up a stack. |
| Topology | Switches in a stack can be connected in a chain or ring topology. A link failure in the chain topology causes the stack to split. In contrast, the ring topology changes into a chain topology upon a link failure so that services in the stack are not affected. Therefore, the ring topology is more reliable than the chain topology.
NOTE: When connecting stack cables, connect stack1 port of one switch to stack2 port of another switch. |
