Service Card Model


For details about service cards, see "Cards" in the Hardware Description of the specific product model.

  • ES1D2X08SED4
  • ES1D2X08SED5
  • ES0D0X12SA00
  • ES1D2X16SFC0
  • ES1D2X40SFC0
  • ES1D2X32SSC0
  • ES1D2X16SSC2


Pluggable Modules on Service Ports

  • 1 m, 3 m, 5 m (passive), and 10 m (active) SFP+ cables

  • SFP+ optical module and fiber

  • 3 m and 10 m SFP+ AOC cables


The ES0D0X12SA00 does not support 3 m and 5 m SFP+ high-speed cables.

  • 1 m, 3 m, and 5 m QSFP+ high-speed cables
  • QSFP+ optical module (except the QSFP-40G-SR-BD model) and fiber
  • 10 m QSFP+ AOC cable (supported since V200R009C00)

Usage Constraints

  • On the ES1D2X08SED4 and ES1D2X08SED5 LPUs, at most four ports can be configured as CSS physical member ports. The four physical member ports must be the first four ports (numbered 0 to 3) or the last four ports (numbered 4 to 7) on the LPUs.

  • On the ES1D2X16SFC0, ES1D2X40SFC0, ES1D2X32SSC0 and ES1D2X16SSC2 LPUs, four contiguous ports must be configured as a group of physical member ports together. The port numbers of the four ports must start with 4xN and end with 4xN+3 (N = 0, 1, 2...). For example, ports 0 to 3 or ports 4 to 7 must be configured together, but ports 2 to 5 cannot be configured together. If any port in a group is configured as a physical member port, the other three ports of the same group must also be configured as physical member ports.

The interconnected CSS physical member ports on the two member switches must be both 40GE ports. XGE ports derived from a 40GE port cannot be added to a logical CSS port.

Hardware Configuration

  • Only two S7706 switches, two S7706 PoE switches, two S7712 switches, one S7706 and one S7712, one S7706 PoE and one S7706, or one S7706 PoE and one S7712 can set up a CSS.
  • MPUs in one chassis must be the same model. MPUs in the local and remote chassis can be the same model or different models; however, the same MPU model is recommended. Two chassis with different SRUs can set up a CSS only in two cases: (1) SRUA in one chassis and SRUB in the other; (2) SRUH in one chassis and SRUE in the other and both chassis run V200R010C00 or a later version.

  • Each chassis can have at most two LPUs for CSS connection. It is recommended that you use the same type of LPUs in a chassis for CSS connection. The two chassis must use the same type of ports for CSS connection, for example, 10GE SFP+ optical ports.

  • Each LPU allows only one logical CSS port. Each logical CSS port supports a maximum of 32 physical member ports.

  • Some ports on an LPU can function as CSS ports, while other ports on the LPU function as service ports.
