Note: Per HP literature, the HP switches with SFP slots do not accept modules other than HP’s own SFPs. The HP switch identifies the manufacturer ID along with the part number and blocks operations to this port for non-HP interfaces.

Transition Networks’ SFP units fully comply with Multi-Sourcing Agreement (MSA). This compliance allows Transition Networks’ SFP modules to be used on other MSA-compliant SFP platforms without any problems.
