Bosch PRA-ES8P2S Ethernet Switch, 8xPoE, 2xSFP

The Bosch PRA-ES8P2S is a compact DIN‑rail mounted Ethernet switch with eight Gigabit copper ports, supporting Power over Ethernet (PoE) and two Gigabit SFP combo ports. This Bosch PRA-ES8P2S Ethernet switch is an OEM switch, made for Bosch by Advantech for use in Bosch Public Address and Voice Alarm systems. It is a preconfigured version of the EKI‑7710G‑2CPI‑AE switch, optimized for PRAESENSA.

The PRA-ES8P2S is certified for EN 54‑16 in combination with PRAESENSA systems. It can be used in addition to the switch ports of the PRAESENSA system controller and multifunction power supply. This is especially convenient in large systems where more SFP ports are needed for long-distance interconnections on glass fiber or more PoE-enabled ports are needed to power PRAESENSA call stations.

Intended for PA/VA Systems

• Managed industrial Gigabit Ethernet switch with convection cooling and DIN‑rail mounting, designed for long term continuous operation.
• Redundant wide-range DC power input.
• Protected against overloads and short circuits.
• Comes with pre‑installed and pre-configured firmware for quick installation and optimum performance.
• Certified for EN 54‑16 in combination with Bosch PRAESENSA systems.

Advanced Features

• Managed switch, configurable via web browser, with eight Gigabit copper ports with PoE and two SFP combo ports for PRA-SFPLX single mode and/or PRA-SFPSX multimode fiber transceiver modules.
• Deactivated Energy Efficient Ethernet (EEE) mode on all ports to avoid problems in combination with audio clock synchronization (IEEE 1588) in combination with OMNEO, Dante, and AES67.
• Wire-speed switching in hardware to avoid variable latency that may cause audio streaming problems.
• Full Quality of Service (QoS) through differentiated services (DiffServ) on all ports, compatible with OMNEO Docent diagnostic tool.
• Support for Rapid Spanning Tree Protocol (RSTP) according to IEEE 802.1d to create redundant loops.
• Fault output relay for fault reporting into PA/VA system.
• Large MAC‑address table (8k‑addresses) for large system broadcasting.
• Support for Simple Network Management Protocol (SNMP) and Link Layer Discovery Protocol (LLDP).
• All copper ports provide PoE (IEEE 802.3 af/at) to power PRAESENSA call stations or other devices.
