ACX500 Indoor Router Description

The ACX500 indoor routers contain a total of 10 ports that support 1-Gbps speed, eight of which are labeled COMBO. At any point of time, you can use a maximum of six ports.

The ports labeled COMBO (combination ports) consist of four Gigabit Ethernet ports that support RJ-45 connectors and four Gigabit Ethernet ports that support small form-factor pluggable (SFP) transceivers. Out of the four RJ-45 ports, three ports support Power over Ethernet (PoE+ and PoE++).

The two ports that are not part of the COMBO ports are Gigabit Ethernet SFP ports.

On the ACX500, the six ports that you can use at any point of time can be two Gigabit Ethernet SFP ports (non-combination) and four ports from the COMBO ports.

Note

You can mix and match the four RJ-45 and SFP COMBO ports as long as the port numbers are unique.

For example, from the COMBO ports, you can use the 0/1/0 SFP port along with the 0/1/1 PoE+ RJ-45 port, but not the 0/1/0 PoE++ RJ-45 port, as the port numbers of the SFP and the RJ-45 ports are same (0/1/0).

The top view and bottom view of an AC-powered ACX500 router are respectively the same as those of a DC-powered router. The only component that appears different is the power inlet for the two routers.

ACX500 Outdoor Router Description

The ACX500 outdoor routers contain three Gigabit Ethernet ports that support SFP transceivers and three Gigabit Ethernet ports that support RJ-45 connectors. The ACX500 outdoor routers install on a pole or a wall, with the chassis installed in a vertical orientation with the cables pointing downward and the eye bolt for hoisting the router pointing upward.

ACX500 Outdoor Router with PoE Description

The ACX500 outdoor routers with Power over Ethernet (PoE) contain three Gigabit Ethernet RJ-45 ports that support PoE+ and three Gigabit Ethernet SFP ports. Out of the three RJ-45 ports, the port labeled 0/1/0 supports PoE++, and the ports labeled 0/1/1 and 0/1/2 support PoE+ with a maximum system PoE power limit of 80 W. The ACX500 outdoor routers with PoE install on a pole or a wall, with the chassis installed in a vertical orientation with the cables pointing downward and the eye bolt for hoisting the router pointing upward.

Alarm Contact Port on ACX500 Routers

The ACX500 router has four external alarm contacts (also known as potential free contacts) for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin D-type connector. The external alarm contact has 15 pins that accept a single core wire from external alarm devices. A DE15 alarm cable is required to connect the ACX500 router to external alarm devices. Use the gauge wire appropriate for the external device that you are connecting.

Whenever a system condition triggers an alarm, the alarm relay contacts are activated, which in turn activates the external alarm devices. The alarm setting is open or closed.

You can connect and configure two output alarms and four input alarms. Two additional output alarms are reserved and are used to indicate major and minor system alarms. Each output and input alarm has two contacts for connecting the router to external alarm devices. Contact 1 of each alarm can be configured as Normally Open [NO] or Normally Closed [NC] through the CLI. Contact 2 of each alarm functions as a reference [REF] or negative potential terminal for Contact 1 of the corresponding alarm and provides a current path for external alarm devices. Table 1 describes the functions of the alarm contacts.

Table 1: Alarm Relay Contact Functions

Contact Name

Contact Name

Function

Contact 1

Normally Open (NO)

Current is not flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current flows, the closed alarm is generated.

Normally Closed (NC)

Current is flowing through Contact 1 and Contact 2 [REF] when operating normally. When the current stops flowing, the open alarm is generated.

Contact 2

Reference (REF)

Provides the current path for the external alarm-reporting device and functions as a reference or negative potential terminal for Contact 1.

Figure 13 shows an example of a wiring diagram for a simple output alarm-reporting device. In this case the device is a light bulb that illuminates when the device encounters a condition that activates the red alarm LED and relay contacts. The alarm relay contacts can also be used to activate other devices such as bells or buzzers.

Figure 14 shows an example of a wiring diagram for a simple input alarm-reporting device. In this case the push button switch is an alarm sensor that triggers an input alarm when a door-open condition occurs.

Tip

You can find information about the pluggable transceivers supported on your Juniper Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector type, the optical and cable characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool allows you to search by product, displaying all the transceivers supported on that device, or category, displaying all the transceivers by interface speed or type. The Hardware Compatibility Tool is located at https://apps.juniper.net/hct/.

The list of supported transceivers for the ACX500 is located at https://pathfinder.juniper.net/hct/product/#prd=ACX500.

Clocking Ports on ACX500 Routers

The clocking ports distribute a synchronized clock signal throughout the router by locking onto a clock signal originating from an internal clock source or by connecting to an external clock source.

The reference clock inputs can be Ethernet recovered clocks, IEEE 1588v2 recovered clocks, or xDSL NTU-R timing clocks. Externally available reference clocks are 1 pulse per second (PPS). The one SubMiniature B (SMB, 1 PPS output) connectors on the front panel of the router connect to external clock signal sources. The clocking ports provide the synchronized output clocks from any one of the above reference inputs based on the clock’s priority.

Internal clock sources within the ACX500 routers include:

  • 1 PPS SMB connectors (one output)

  • Time of day (TOD) RJ-45 port (supports RS-422)

  • Synchronous Ethernet support on RJ-45 and SFP ports as timing input or output

  • Packet timing (IEEE 1588v2) includes:

    • Timing input when configured as ordinary clock (OC) or boundary clock (BC)

    • Timing output when configured as BC
