J2320 and J2350 External Compact Flashes

On J2320 and J2350 routers, an external compact flash, also known as removable compact flash, accepts a type I or II compact flash, as defined in the CompactFlash Specification published by the CompactFlash Association. The J2320 and J2350 chassis has a slot on the rear for external compact flashes (see Figure 3 on page 9). When the external compact flash is installed and configured, it automatically acts as the secondary boot device if the internal compact flash fails on startup.

Depending on the capacity of the external compact flash, you can also configure it to receive any core files generated during a failure. For information about configuring an external compact flash, see the JUNOS Software Administration Guide.

J2320 Power System

The J2320 Services Router uses AC power (see Figure 3 on page 9). The autosensing power supply distributes the different output voltages to the router components according to their voltage requirements. The power supply is fixed in the chassis, and is not field-replaceable.

The AC power supply has a single AC appliance inlet that requires a dedicated AC power feed.

The J2320 AC-powered chassis has a power switch and does not include a power

LED.

For information about site power preparations, see “Power Guidelines, Requirements, and Specifications” on page 67. For information about connecting the router to power and ground, see “Connecting Power” on page 84.

J2350 Power System

The J2350 Services Router uses either AC or DC power. The autosensing power supply (see Figure 4 on page 9 or Figure 5 on page 10) distributes the different output voltages to the router components according to their voltage requirements. The power supply is fixed in the chassis, and is not field-replaceable.

The AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. The DC power supply has a terminal block that provides a single DC input (–48 VDC and return) and requires a dedicated 15 A (–48 VDC) circuit breaker.

The J2350 AC-powered or DC-powered chassis has a power switch and does not include a power LED.
