Stack cards and the bandwidth of the S5700

15

The subcards in the front slot and rear slot use the same chip that provides 4 x 10 Gbit/s bandwidth. Therefore, the S5700EI or S5700SI stacks set up in stack card connection mode have the following limitations:
A stack subcard can be used with a 2x10GE subcard. In this case, each stack port occupies 10 Gbit/s bandwidth, and on the front subcard, each port also occupies 10 Gbit/s bandwidth. A stack card cannot be used with a 4x10GE subcard. This is because the 10GE ports on the 4x10GE subcard are actually 10GE ports with their rates limited, so the actual bandwidth of the subcard is 4 x 10 Gbit/s. This subcard occupies all the 4 x 10 Gbit/s bandwidth of the chip, so there is no available bandwidth for the stack card.

What is the bandwidth limitation on subcards
The subcards in the front slot and rear slot use the same chip that provides 4x10 Gbit/s bandwidth. Therefore, the S5700EI or S5700SI stacks set up through stack cards have the following limitations: A stack card can be used with a 2x10G subcard. The two stack interfaces on the stack card occupy 20 Gbit/s bandwidth, and the 2 x 10G subcard occupies 20 Gbit/s. A stack subcard cannot be used with a 4 x GE subcard. The GE interfaces on the 4 x GE subcard are actually 10GE interfaces with their rates limited, so the actual bandwidth of the subcard is 4x10 Gbit/s. This subcard occupies all the 4x10 Gbit/s bandwidth of the chip, and thus there is no available bandwidth for the stack card.

Are the cards of S5700 hot swappable
Interface cards on the S5700 series except for the S5700EI and S5700SI are hot swappable.

Whether S series fixed switches support stacking
The Typical Configuration Examples document describes whether each model and version of S series fixed switches (except S1700 switches) supports stacking as well as stack modes, hardware and software requirements, typical networking, and configuration steps.
