Step 5: Connect External Devices and Cables
All the connections to the router are made through the front panel.
Connect the Router to a Network for Out-of-Band Management
To connect the router to a network for out-of-band management,
connect an Ethernet cable with RJ-45 connectors to the MGMT
port on the router. We provide one Ethernet cable with the router.
Use shielded CAT5e cable for the CON
and MGMT
ports on the router.
To connect to the MGMT
port on the front
panel of the router:
- Turn off power to the management device.
- Plug one end of the Ethernet cable (Figure 42 shows the connector) into the
MGMT
port on the router. - Plug the other end of the cable into the network device.

Table 4 describes the out-of-band management port for the ACX5400 router.

Connect the Router to a Console Device
To use a system console to configure and manage the router,
connect it to the appropriate CON
port on the
router. The console port is used to connect a laptop or console terminal
to configure the router (see Figure 43 and Figure 44). The console port accepts a cable with an
RJ-45 connector. We provide one serial cable with an RJ-45 connector
and a DB-9 connector with the router.
Use shielded CAT5e cable for connecting the CON
and MGMT
ports on the router.
To connect a management console:
- Turn off power to the console device.
- Plug the RJ-45 end of the serial cable (see Figure 42) into the
CON
port on the router. - Plug the female DB-9 end into the device's serial port.
Note For console devices, configure the serial port as follows:
Baud rate—9600
Parity—N
Data bits—8
Stop bits—1
Flow control—none


Table 5 describes the console port for the ACX5400 router.

Connect the Router to External Clocking and Timing Devices
The router has two SMB connector ports that support 1-PPS and 10-MHz timing devices.
Ensure that you use a cable of 3 m or less in length for the 10-MHz and 1-PPS connectors.
To connect the SMB to BNC coaxial cable to the external clocking input port:
- Connect one end of the SMB to BNC coaxial cable to either the 1-PPS connector or the 10-MHz connector on the router.
- Connect the other end of the SMB to BNC coaxial cable
to the 1-PPS or 10-MHz measurement equipment.
Note Ensure that the 10-MHz or 1-PPS source network equipment contains low-voltage complementary metal oxide semiconductor (CMOS) or is compatible with low-voltage (3.3 V) transistor-transistor logic (TTL).
Table 6 describes the clocking ports on the ACX5400 router.
