HIRSCHMANN MM20-P9T1T1T1SAHH hot-swappable hybrid media module

Product Overview

The HIRSCHMANN MM20-P9T1T1T1SAHH is a hot-swappable hybrid media module engineered for Hirschmann's MICE switch series (MS20 and MS30 basic switches).

Equipped with 1 × Single-Mode SC Fiber Port ($1300text{ nm}$, up to $30text{ km}$ distance) and 3 × RJ45 Copper Ports (10/100Base-TX), this module enables long-haul optical uplink transmission back to central control networks while serving local equipment via high-density copper drops.

4. Operating Instructions

Installation Steps

ESD Grounding: Always wear an anti-static grounding wrist strap connected to cabinet earth before handling the module.

Module Alignment: Slide the MM20 card into the guide rails of an open media slot on the host MS20 or MS30 basic switch.

Mechanical Lock: Press firmly until the backplane connector locks in place. Hand-tighten top and bottom captive thumbscrews on the front faceplate to ensure chassis ground grounding.

Cabling: Attach single-mode duplex SC optical jumpers to Port 1 and RJ45 Ethernet patch cables to Ports 2. 3. and 4.

Hot-Swap Protection: You can safely pull or insert this module while the main switch is powered on without interrupting communications on adjacent switch slots.

6. Storage Conditions

Storage Temperature: $-40^circtext{C}$ to $+70^circtext{C}$ in original anti-static protective packaging.

Humidity Control: $< 95%$ relative humidity (non-condensing).

Optical Dust Caps: Keep protective rubber plugs inserted inside the SC fiber port whenever not connected to prevent optical lens contamination.
