EMS100G32-R2 SWITCH

INTRODUCTION

The EMS100G32-R2 switch is a full-featured, fixed form-factor top-of-rack (ToR) compact 10/25/40/50/100/200GbE

switch for data center networks with small form-factor pluggable plus (SFP+), small form-factor pluggable 28 (SFP28),

quad small form-factor pluggable 28 (QSFP28), and quad small form-factor pluggable double density (QSFP-DD)

ports. In addition, the switch is a 10/25/40/50/100/200GbE switch with 10/25GbE links for server connections and

40/50/100GbE links for clustering—virtual link trunking (VLT) and stacking—and uplinks to aggregation and core

switches. The switch includes two hot-swappable AC or DC power supply units (PSUs) and four hot-swappable fan

units.

EMS100G32-R2 is a one-rack unit that includes (32) 100GbE QSFP28 ports and (2) 10GbE SFP+ ports.

It supports the following configurations:

96 x 10GbE + 8 x 100GbE

96 x 25GbE + 8 x 100GbE

128 x 10GbE
