Cable Ports
The MP-372 has two RJ-45 ports. (See Figure 2.) Each port provides a
10/100BASE-TX Ethernet connection to an MX switch. The connection can be
direct to an MX-switch 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 switch or other device in the network. The MP-372
supports 802.3af, and also can receive PoE from Trapeze switches and
Trapeze-approved power injectors. (See the Release Notes for Trapeze Networks
Mobility Point Access Points.)
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 access point to an MX switch. 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. MP access points do not support daisy-chain configurations. Do not
connect the MP access point to another MP access point.
