S5700HI, S5710HI, and S5720HI Service Port Stacking Support

S5700HI, S5710HI, and S5720HI Service Port Stacking Support

NOTE:
  • For the cables that can be used as stack cables, see "Cables" in the Hardware Description. Using other cables may cause exceptions in the stack system, for example, frequent error-down events on stack ports.
  • Combo ports cannot function as stack member ports.
  • For stacking-supported service ports, some of them can be used as stack ports, whereas some can be used as ordinary service ports.
  • Since V200R011C10, S5720HI series switches can set up stacks in service port stacking mode using dedicated stack cables.
  • The number of S5700HIs or S5710HIs used to set up a stack is recommended to be 2 to 5, and the number of S5720HIs used to set up a stack is recommended to be 2 to 9.

Remarks

S5700HI

10GE ports on front cards: The S5700HI supports ES5D00X2SA00 and ES5D00X4SA00 front cards, which support two and four 10GE SFP+ optical ports respectively.
  • 1 m and 3 m SFP+ passive high-speed copper cables
  • 10 m SFP+ active high-speed copper cables
  • 3 m and 10 m AOC cables
  • 10GE SFP+ optical module and optical fiber

10 Gbit/s

  • Any models of the S5700HI series can set up a stack.
  • A switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most four stack member ports. A switch supports a maximum of four stack member ports.
  • After a front card is replaced by a card of a different type, the stack configurations become ineffective and need to be performed again.
S5710HI 8*10GE ports on the front panel
  • 3 m and 10 m AOC cables
  • 10GE SFP+ optical module and optical fiber
10 Gbit/s
  • Any models of the S5710HI series can set up a stack.
  • A switch supports a maximum of two logical stack ports, and each logical stack port supports at least one stack member port and at most four stack member ports. Each switch can use a maximum of eight service ports as stack member ports.

S5720HI

Four SFP+ optical ports

  • 1 m, 3 m, and 5 m SFP+ passive high-speed copper cables
  • 10 m SFP+ active high-speed copper cables
  • 3 m and 10 m AOC cables
  • 10GE SFP+ optical module and optical fiber
  • 0.5 m and 1.5 m SFP+ dedicated stack cable (supported in V200R011C10 and later versions)
10 Gbit/s
  • Any models of the S5720HI series can set up a stack.
  • A switch supports a maximum of two logical stack ports, and each logical stack port supports a maximum of eight stack member ports. Each switch can use a maximum of eight service ports as stack member ports.

NOTE:

An S5720HI supports the stacking function since V200R009C00. When a member device in a stack is faulty and fails to restart for three consecutive times, the device attempts to roll back to a version earlier than V200R009C00 for restart. When the device restarts successfully after rolling back to a version earlier than V200R009C00, a multi-active situation may occur because the version earlier than V200R009C00 does not support the stacking function. To prevent this situation, you are advised to delete the system software earlier than V200R009C00 from member devices when using S5720HIs to set up a stack.

Ports on a 4-port 10GE interface card

  • 1 m, 3 m, and 5 m SFP+ passive high-speed copper cables
  • 10 m SFP+ active high-speed copper cables
  • 3 m and 10 m AOC cables
  • 10GE SFP+ optical module and optical fiber
