Introduction

The ES02VSTSA provides four 16GE optical ports, which can only be used for cluster connection and cannot be used for data transmission and switching.

Multiple switches can be connected through ports on the ES02VSTSA cards to set up a switching domain and function as one logical device. You can manage all the switches in a switching domain on the master switch.

The ES02VSTSA can be installed in the subcard slot of ES0D00SRUA00, ES1D2SRUAC00 and ES0D00SRUB00. To configure the CSS service, install ES02VSTSA cards on both SRUs in a chassis.

Functions

Switches connected through ports on the cards set up a cluster and are managed as one device. You can log in to the master switch to manage all the switches in the cluster.

Usage Constraints

• The ES02VSTSA does not support hot swap and can only be installed or removed before the SRU is powered on.

• The ES0D00FSUA00 and the ES02VSTSA are installed in the subcard slots of the SRUs; however, they cannot be installed simultaneously on the SRUs in the same chassis or CSS.

Indicators and Ports

Figure 7-58 Ports on the ES02VSTSA panel

The S7700 only supports a CSS of two switches. To connect two S7700 switches through ES02VSTSA cards, connect the ports on the ES02VSTSA cards according to Figure 7-59.

Figure 7-59 Cable connection between CSS ports

QSFP+ high-speed cables, optical fibers, and AOC cables can be used as cluster cables to connect CSS ports on the ES02VSTSA cards. CSS-capable S7706, S7706 PoE, or S7712 switches can be connected through the cluster cables to form a logical switch.

• To use high-speed cables as cluster cables, select 3 m or 5 m (since V200R011C10) cables (High-Speed Cable).

• To use optical fibers as cluster cables, select the QSFP-40G-SR4, QSFP-40G-iSR4, or QSFP-40G-eSR4 optical module (in this case, the module cannot connect a 40GE port to four 10GE ports using a 1-to-4 cable) and MPO-MPO fiber jumpers. For details about the optical modules and fiber jumpers, see 40GE QSFP+ Optical Modules and Optical Fiber.

  Two types of MPO-MPO jumpers can be used to connect CSS ports:

  • OM3: The maximum transmission distance is 100 m.
  • OM4: The maximum transmission distance is 150 m.
• To use AOC cables as cluster cables, select AOC cables according to 10 m QSFP+ - QSFP+ AOC cable (supported in V200R010C00 and later versions).
