Note
It is possible to insert and remove the media modules during operation. Before
inserting a media module, remove the cover and cap from the slot. Please put
these away for safe keeping. If you remove a media module, close the the terminal
strip with the cap and and the slot with the cover.
Options for Slot 5
Slot 5 of the basic device has two RJ-45 jacks for connecting TP cables. The pos-
sible data transmission rates on electrical connections are 10, 100, or 1000 Mbps.
An optical gigabit module in slot 5 allows data transmission with multimode or sin-
gle mode FOC. In this case, the two RJ-45 jacks can no longer be used.
Options for Slots 6 and 7
Slots 6 and 7 do not have any ports but allow two optical fast Ethernet modules to
be inserted each with ports. This gives you the opportunity of data transmission at
a data transmission rate of 100 Mbps over multimode or single mode FOC.
