Cable Ports
The Indoor MPs have two RJ-45 ports. (See
Figure 1–2.) Each port provides a 10/100BASE-TX
Ethernet connection to an MX (with the exception of the MP-432, which has a 10/1000BASE-TX).
The connection can be direct to an MX or indirect through an intermediate Layer 2 or Layer 3
network.
The MP receives power and data through the RJ-45 ports. Use a Category 5 (Cat 5) cable with
straight-through signaling and standard RJ-45 connectors to connect an MP to an MX or other
device in the network. The Indoor MP supports 802.3af, and also can receive PoE from Trapeze
MX appliances and Trapeze-approved power injectors.
The two RJ-45 ports support dual-homed configurations for redundancy. An MP uses only one link
for booting, configuration, and data transfer. If the link becomes unavailable, the MP can reboot
using the other link. The ports are identical except for logical numbering (1 or 2). You can use
either port to connect an MP to an MX. However, an MP always attempts to boot on MP port 1
first. Only if the boot attempt on port 1 fails does the MP attempt to boot on port 2. If one port
becomes unavailable, the other port can provide full power to the MP.
Note:
MPs do not support daisy-chain configurations. Do not connect the MP to another MP.
