ES5D00ETPC00 (Stack Rear Card)
Version Mapping
Table 8-188 lists the mapping between the ES5D00ETPC00 card and software versions.
Card Overview
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.

|---|---|
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. Figure 8-94 and Figure 8-95 show the chain and ring topologies. NOTE:
When connecting stack cables, connect stack1 port of one switch to stack2 port of another switch. |
Usage Constraints
The following requirements must be met to set up a stack:
- All the member switches belong to the same series. The EI series and SI series cannot form a stack.
- All switches have stack cards installed and are connected using PCIe cables.
- The ES5D00ETPC00 is not hot swappable, but PCIe cables are hot swappable.

Stack electrical port
The ES5D00ETPC00 provides two 12 Gbit/s electrical ports for stacking. The two 12 Gbit/s electrical ports must be used with PCIe Cables. Table 8-191 describes attributes of the 12 Gbit/s electrical port.
