Soulution:

It seems RSP module got an issue. Fortunately, there is a standby RSP720 in warehouse. After replaced RSP720, it booted normally.

Route switch processor (RSP) is a module that is installed in one of the card slots in the router. The RSP provides switching and local and remote management for the router and also contains the uplink ports for the router. Both types of modules (supervisor engine and RSP) perform the same functions in the router.

Cisco Router 7206 with RSP720-3CXL-GE


RSP720-3CXL-GE

Two Gigabit Ethernet uplink ports: port 1 supports a 1-Gbps SFP module; port 2 is configurable with either a 1-Gbps SFP module or a 10/100/1000-Mbps RJ-45 connector

Integrated 720-Gbps switch fabric

PFC3CXL (high-capacity) and MSFC4 with 512-MB bootdisk 4-MB NVRAM, 4-MB ROMmon, and several DRAM options:

Route processor (RP): 1- to 4-GB DRAM (default 2 GB)

Switch processor (SP): 1- to 2-GB DRAM (default 1GB)

Two CompactFlash Type II slots on front panel (512 MB default with option to 1 GB) and two internal CompactFlash slots (one each for RP and SP, 512 MB default for each)

Requires larger power supplies and a high-speed fan tray

QoS port architecture (Rx/Tx): 1p1q4t/1p2q2t
