About GRM20-TTTTTTTTSZ9HHS
The Hirschmann GRM20-TTTTTTTTSZ9HHS Greyhound series media module is a rack-mounted switch media module designed to provide a low-cost industrial Ethernet switch connection solution to industrial automation applications. The GRM20-TTTTTTTTSZ9HHS media module belongs to the Hirschman Greyhound series of 19-inch rack-mounted switches and media modules, and it is designed for harsh industrial conditions. The GRM20-TTTTTTTTSZ9HHS media module has a maximum port density of 8 twisted pair copper cable ports that expand the connection capabilities of a Greyhound switch. Each port has an RJ45 connector socket and it supports auto-negotiation, auto-crossing, and auto-polarity functions. The GRM20-TTTTTTTTSZ9HHS media module offers fast and seamless configuration, setup, and diagnostics via a command-line interface (station manager or PC) or via a USB configuration port. The user configuration data and the switch operating system can be saved and stored on an external flash-based configuration device and uploaded directly to save programming time and reduce overall commissioning time.
The Hirschmann Greyhound GRM20-TTTTTTTTSZ9HHS media module has an RJ-45 V.24 Serial interface port for local connection to a PC or a station manager device. The GRM20-TTTTTTTTSZ9HHS media module has the CE, FCC, and EU Safety Standards approvals. It has a rated operating temperature range of 0 to 60 degrees Celsius and a working relative humidity range of 5 to 95% (non-condensing). The GRM20-TTTTTTTTSZ9HHS media module has a maximum power consumption rating of 2 Watts. Power is supplied via the host Greyhound switch, which delivers 48 to 54 Volts DC operating voltage over the power cable. The GRM20-TTTTTTTTSZ9HHS media module supports the Greyhound power supply configurator, which provides power over Ethernet (PoE and POE+) that conforms to IEEE 802.3af standard via twisted-pair Ethernet cables. The GRM20-TTTTTTTTSZ9HHS media module’s power supply powers end devices such as VoIP phones, Wireless Access Points (WAPs), and IP cameras rated at up to 180 Watts.
