ACX7348 Chassis

SUMMARY Learn about the ACX7348 router chassis, the field replaceable units (FRUs), and physical specifications of the router and the FRUs.

ACX7348 Chassis Description

The router chassis is a rigid sheet metal structure that houses all the router components. The ACX7348 router has a fixed Flexible PIC Concentrator (FPC), dual Routing Engines, three bays for pluggable FPCs, redundant AC or DC power supply modules (PSMs), and four fan trays (two fans per tray).

Figure 1 shows the front of the chassis configured with two Routing Engines. The chassis measures 5.21 in. (13.23 cm) high, 16.92 in. (42.97 cm) wide, and 11.41 in. (28.98 cm) deep. The chassis installs in a standard 800-mm deep open rack, 19-in. equipment racks, or telco open-frame racks. For more information about the physical specifications of the router and its components, see Table 4.

Fixed FPC

The ACX7348 router has a fixed flexible PIC concentrator (FPC) that has 48 small form-factor pluggable 28 (SFP28) ports with MACsec capabilities and 8 quad small form-factor pluggable 28 (QSFP28) ports. Table 1 shows the port speeds that the fixed FPC supports.

Description

Green

Blinking

System has no primary Routing Engine.

On steadily

The system is functioning normally.

Red

Blinking

One or more fans are not installed in the router before the software is up and running.

On steadily

The fixed FPC has a power-related fault.

Timing Ports

Figure 4 lists the components on the ACX7348 router's timing ports.

Here's a definition of the ports and labels on the timing ports. See Table 3 for a description of the timing ports LED indicators.

  • GNSS antenna port—Connects to a GNSS antenna.
  • BITS—Building-integrated timing supply (BITS) external clocking interface for connecting to external clocking devices.

  • 10MHz (I/O)—10-MHz input and output clocking port for connecting to external clock signal sources. The clocking port synchronizes clock inputs based on the clock’s priority.

  • PPS—1-pulse per second (PPS) output connector for connecting to external clock signal sources. The clocking port synchronizes clock inputs based on the clock’s priority.
