MM22-T1T1T1T1 PoE media module
The MM22-T1T1T1T1 PoE media module (deeper module design)
supports Power over ETHERNET (PoE) according to IEEE 802.3af. It
allows the connection and remote supply of IP telephones (Voice over IP),
webcams, sensors, printer servers and WLAN access points via 10BASE-
T/100BASE-TX, for example. With PoE, these terminal devices are
powered by the twisted-pair cable.
The MM22-T1T1T1T1 media module has four 10BASE-T/100BASE-TX
ports (RJ45 connections) for connecting network segments or PoE
terminal devices (PD, Powered Device) up to class 0 (or respectively
class 3).
The current is supplied on the free line pair (spare pairs); the individual
ports are not electrically insulated from each other.
The following conditions are met in accordance with IEEE 802.3af:
 Endpoint PSE
 Alternative B.

MM4 media modules
The 4-port MM4-4TX/SFP media module has 4 TP interfaces and 4
sockets for SFP transceivers from Hirschmann.
The 2-port MM4-2TX/SFP media module has 2 TP interfaces and 2
sockets for SFP transceivers from Hirschmann.
The Gigabit slot of the MS30 device (slot on the left side next to the switch
basic module) supports 2 Gigabit ports.
By inserting a SFP transceiver, you deactivate automatically the
corresponding twisted pair interface.
Note: Only use Hirschmann SFP transceivers.
See “Media modules: Power consumption, Power output, operating
temperature surrounding air, order numbers” on page 73.
