The built-in tunnel interface on the CFEB or CFEB-E is configured the same way as a
PIC. For information about configuring the built-in tunnel interface, see the Junos OS
Services Interfaces Library for Routing Devices.
Optional Adaptive Services Module (ASM)—Provides one or more services on one PIC.
See "M7i Adaptive Services Module" on page 67
The CFEB and CFEB-E are hot-pluggable when you replace a CFEB with a CFEB or a
CFEB-E with a CFEB-E. Upgrading or downgrading a CFEB device requires a system
reboot, as described in "Upgrading and Downgrading the CFEB and CFEB-E" on page
You can remove and replace the CFEB or CFEB-E without powering down the router, but
the routing functions of the system are interrupted when it is removed.
The CFEB has the following major components:
Processing components:
266-MHz CPU and supporting circuitry
Integrated ASIC
33-MHz PCI bus
Storage components:
128-MB SDRAM for packet memory
128-MB SDRAM for the microkernel
8-MB SSRAM for route lookup
4-MB SSRAM for control memory
Services interfaces:
Built-in tunnel interface
Optional Adaptive Services Module
System interfaces:
100-Mbps link for internal interface to the Routing Engine
19.44-MHz reference clock—Generates clock signal for SONET/SDH PICs.
I2C controller to read the I2C/EEPROMs in the PICs and temperature sensors
I2C/EEPROM containing the serial number and revision level
Two 512-KB boot flash EPROMs (programmable on the board)
One PowerPC 8245 integrated processor
Three LEDs—A green LED labeled
indicate CFEB status.
