4.10.1 Functions and Applications

Functions
The ETPC provides two 12 Gbit/s electrical interfaces to implement data access and line-speed
switching.
Multiple switches can be connected using ETPC cards to function as a logical device (stack). A
maximum of nine S5700 switches are supported in a stack system.
Applications
The ETPC can be installed on the S5700-24TP-SI-AC, S5700-24TP-SI-DC, S5700-48TP-SI-
AC, S5700-48TP-SI-DC, S5700-28C-EI, S5700-52C-EI, S5700-28C-EI-24S, S5700-28C-SI,
S5700-52C-SI, S5700-24TP-PWR-SI, S5700-48TP-PWR-SI, S5700-28C-PWR-EI, or
S5700-52C-PWR-EI for stacking.
The following requirements must be met to implement stacking:
l All the member switches belong to the same series. The EI series and SI series cannot form
l All the member switches are connected using stack cables and stack modules.
