MSBR Series 43 Mediant 800 MSBR
Hardware Installation Manual 6. Cabling the Device
6.3 Connecting to LAN
The device provides up to four Gigabit Ethernet (10/100/1000Base-T) LAN RJ-45, ports and
eight RJ-45 10/100Base-TX (Fast Ethernet) LAN ports for connection to the LAN (e.g.,
computers, switches, and IP phones). These ports support half- and full-duplex modes,
auto-negotiation, and straight or crossover cable detection. The LAN ports can also support
PoE. For connecting PoE-enabled equipment to the LAN ports, see Section 6.4 on
page 44.
