ACX7509 Management Cable Specifications and Pinouts

SUMMARY The ACX7509 router relies on connections through specific management cables, ports, and pinouts to communicate effectively with management devices such as laptops.

Management Cable Specifications for ACX7509 Routers

Table 1 lists the specifications for the cables that connect the console and management ports on Juniper Networks devices to management devices such as laptops.

Table 1: Specifications of Cables to Connect to Management Devices
Type of port	Cable specification	Receptacle	Additional information
RJ-45 console port	CAT5e unshielded twisted pair (UTP) cable	RJ-45	Connect an ACX7509 Router to a Management Console
Management Ethernet port	Ethernet cable with an RJ-45 connector	RJ-45	Connect an ACX7509 Router to a Network for Out-of-Band Management

RJ-45 to DB-9 Serial Port Adapter Pinout Information

The console port is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a laptop or a desktop PC. If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop PC to the device, use a combination of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug adapter. This table provides the pinout information for the RJ-45 to DB-9 serial port adapter.

RJ-45 Pin	Signal	DB-9 Pin	Signal
3	TxD	2	RxD
6	RxD	3	TxD
7	DCD	1	DCD

Console/ToD Port Connector Pinout on ACX7509 Routers

The console/ToD port (labeled CON) on the Routing and Control Board (RCB) panel is a multiplexed connector for both console and ToD. Console and ToD are RS-232 serial interfaces. A split cable is needed for using both Console and ToD together. If the console port alone is used, then the split cable is not needed. When the split cable is used, console logout on disconnect will not be supported. The baud rate for the console port must be set to 115200 baud.

Use a cable with the pinouts described in Table 2 to connect an ACX7509 to a console management device.

Note:

If your laptop or PC does not have a DB-9 pin contact and you want to connect your laptop or PC directly to an ACX7509, use a combination of the RJ-45 to DB-9 socket adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.

USB Port Specifications for the ACX7509 Routers

The following Juniper Networks USB flash drives have been tested and are officially supported for the USB port in the ACX7509 routers:

RE-USB-1G-S—1-gigabyte (GB) USB flash drive
RE-USB-2G-S—2-GB USB flash drive
RE-USB-4G-S—4-GB USB flash drive

CAUTION:

Any USB memory product not listed as supported for the ACX7509 routers has not been tested by Juniper Networks. The use of any unsupported USB memory product could expose your device to unpredictable behavior. Juniper Networks Technical Assistance Center (JTAC) can provide only limited support for issues related to unsupported hardware. We strongly recommend that you use only supported USB flash drives.
