Description

SSN1EGSH overview

The EGSH is used to transmit/receive Ethernet services, manage bandwidths, and realize Layer 2 switching of Ethernet services.

Valid Slots

The EGSH must be installed in a valid slot in the subrack. Otherwise, the EGSH fails to work normally.

The EGSH can be installed in slots 2-8 and 11-17, the bandwidth is 10 Gbit/s.

Feature Code

The number code that follows the board name in the bar code is the feature code of the board. The feature code of the EGSH indicates the type of optical interface.
