เปิดดูภายในเราเตอร์ BELKIN F5D7634-4 v2

เราเตอร์ตัวนี้ผมได้มาสภาพไม่ปกติคือ พอร์ตแลนใช้ได้ 2 ช่อง เลยลองแกะเล่นดูครับ แกะแล้วเห็นวงจรภายในไม่เหมือนใครดี มาดูกันครับ

ภายในเราเตอร์
ตัวเราเตอร์มี CPU 2 ตัว ตัวแรกเป็น CPU ของวงจร ADSL ชื่อ Infineon PSB 50600 HL

CPU1:  Infineon PSB 50600 HL

CPU ตัวที่ 2 เป็นส่วนทำหน้าที่เป็นเราเตอร์และปล่อย WiFi ชื่อ Ralink RT3050F

CPU2: Ralink RT3050F

RAM ของ ADSL CPU ชื่อ EtronTech EM639165TS-6G มีขนาด 16 MB

RAM1: EtronTech EM639165TS-6G

RAM ของ CPU เราเตอร์ชื่อ Zentel A3V64S40ETP-G6 มีขนาด 8MB

RAM2: Zentel A3V64S40ETP-G6


Flash Memory ของ ADSL CPU คือ MX29LV160DBTI-70G มีขนาด 2MB

Flash1: MX29LV160DBTI-70G

หน่วยความจำ CPU ของเราเตอร์เป็นไอซีไม่ทราบชนิดอาจจะเป็น eeprom หรือ Flash เบอร์ ATMLH940

 ATMLH940
ส่วนของภาคจ่ายไฟของเราเตอร์มีไอซี Switching ควบคุมอยู่สองตัวซึ่งเป็นเบอร์เดียวกันคือ WE16B8

WE16B8

ส่วนของพอร์ต Serial มี 2 ชุดคือของ ADSL กับ CPU เราเตอร์

ขา Serial

จาก Boot log ด้านบนพอสรุปกระบวนการได้ คือ
  • ADSL CPU บูตตัวเองขึ้นมาก่อน แล้วส่งเฟิร์มแวร์ผ่านทาง Ethernet ภายในไปหา RT3050F 
  • หลังจากโหลดเสร็จ RT3050F บูตตัวเองจาก RAM 
ภายในเราเตอร์เป็น OS เฉพาะทางไม่น่าใช่ Linux ครับ
