NOTE:
• To guarantee the functionality of the SFP ports, always use H3C SFP transceiver modules on the H3C
S3100V2 Switch Series.
• The SFP-STACK-Kit module is dedicated for connecting switches and has connected to a 1.5 m (4.92
ft)
cable.
• The SFP transceiver modules available for this switch series are subject to chan
e over time. For the mos
up-to-date list of SFP transceiver modules, consult your H3C sales representative or technical support
engineer.
