ACX4000 Power Overview IN THIS SECTION AC Power Supplies | 59 DC Power Supplies | 60 The ACX4000 router uses either AC or DC power supplies (see Figure 10 on page 59 Figure 11 on page 60). The power supplies are located in the front of the chassis and offer 1+1 redundancy. The power supply slots are labeled PS 0 and PS 1.
Page 68 configuration with full power for as long as the router is operational. A second power supply can be installed for redundancy. Each power supply is cooled by its own internal cooling system. Redundant power supplies are hot-removable and hot-insertable. When you remove a power supply from a router that uses only one power supply, the router might shut down depending on your configuration.

See the Junos OS documentation for your device for a description of the monitoring fields. CAUTION: If you face a problem running a Juniper Networks device that uses a third- party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem.
Page 92: Calculating Power Budget And Power Margin For Fiber-Optic Cables
TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device. To calculate the power budget and power margin, perform the following tasks: How to Calculate Power Budget for Fiber-Optic Cables To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit.
Page 93: How To Calculate Power Margin For Fiber-Optic Cables
How to Calculate Power Margin for Fiber-Optic Cables After calculating a link's power budget, you can calculate the power margin (P ), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (P ).
Page 94: Fiber-Optic Cable Signal Loss, Attenuation, And Dispersion
= 13 dB – 2 km (1 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB = 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB = 7 dB The following sample calculation for an 8-km-long single-mode link with a power budget (P ) of 13 dB uses the estimated values from Table 26 on page...
Page 95 Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.
