Cable Ports
MP access point models MP-241, MP-252, and MP-262 have 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 network.
The MP receives power and data through the ports. Use a Category 5 (Cat 5) cable
with straight-through signaling and standard RJ-45 connectors to connect the MP
access point to an MX switch or other device in the network.
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 both ports are directly connected to MX switch ports supplying Power over
Ethernet (PoE), the ports load-share. If one port becomes unavailable, the other
port can provide full power to the MP.
MP model MP-52 has one RJ-45 port for direct or indirect connection to an MX
switch.
External Antenna Connector
Model MP-262 has a connector for attaching an external sectorized antenna for
the 802.11b/g radio. (See Figure 2.) An external antenna is required for the
802.11b/g radio. The radio does not have an internal antenna. Table 2 lists the
MP-262 external antennas.
Note.
MP access points do not support daisy-chain configurations. Do not
connect the MP access point to another MP access point.
