Product Introduction
The Hirschmann RSPE30-24044O7T99-TCCVP99HHSE2S is a modular managed switch built for substation and transportation networks. It ships with 4 Gigabit combo ports and 8 Fast Ethernet TX ports, expandable to 28 ports via two media modules.
The TCCVP99HHSE2S suffix confirms the critical specs: Extended temperature with conformal coating (T), dual AC/DC power (CC), substation approvals (VP), and standard hardware configuration (S). The 09.0.02 indicates HiOS firmware release 09.0.02. This unit runs HSR/PRP zero-switchover redundancy, making it suitable for IEC 61850 station bus applications where a single dropped frame is unacceptable.
Frequently Asked Questions
Q: Can I hot-swap media modules while the switch is running?
A: No. The media module slots are not designed for live insertion. Power the unit down, discharge static, then install or remove modules. In our experience, hot-plugging a module into an RSPE30 can corrupt the boot configuration and force a factory reset.
Q: The part number ends in S09.0.02. What firmware is that?
A: That is HiOS Release 09.0.02. Before deploying, verify your network management platform supports this release. If you run Industrial HiVision or a third-party NMS, check the MIB compatibility. Downgrading HiOS below 08.x requires a different software image and is not always straightforward.
Q: What is the most common mistake when ordering this switch?
A: Confusing the media module slots with pre-installed ports. The 24044O7T99 code means the base unit has 4 combo + 8 TX ports and two empty slots. If you need 24 Fast Ethernet ports, you must order two 8-port media modules separately. The switch will not reach 24 FE ports out of the box.
Q: Is this switch certified for substation use?
A: Yes, the VP approval code covers IEC 61850-3 and IEEE 1613. That means it meets the EMI and environmental requirements for protection and control rooms. It does not automatically qualify for Class I Div 2 hazardous areas unless the approval code includes ATEX or ISA 12.12 markings—this unit does not.
Q: What redundancy protocols does this specific unit support?
A: The HH and S codes indicate standard Hirschmann configuration with standard hardware. You get RSTP, MRP, and Link Aggregation out of the box. HSR and PRP require the RSPE35 or RSPE37 hardware variants—those have dedicated redundancy acceleration circuitry. This RSPE30 does not support zero-switchover HSR/PRP.
