Problem Fan Tray [Cisco CRS3] on IOS XR 4.2.4

Tepatnya hari Kamis, saya menemukan beberapa keanehan di Cisco CRS-3 Line card chassis Enhanced yang baru saja tiba di site. Ketika power on dan boot up, indikator LED di PRP mengalami masalah. LED indikator yang saya maksud adalah LED indicator yang menunjukan proses booting atau idle yang ada pada PRP. terlihat sekilas saat booting proses si LED menyatakan “Fan Tray Alarm”. Setelah booting selesai, kini normal dan menujukan kalau PRP sebagai ACTIVE PRP. Saat itu, IOSXR yang digunakan adalah versi 5.1.1 bawaan pabrik.

Sesuai rekomendasi Cisco NOS tahun lalu, IOS XR yang harus digunakan adalah versi 4.2.4. Untuk itu, saya pun melakukan instalasi IOS XR 4.2.4. Saat selesai menginstall IOS XR ini dan seperti biasa si chasis minta untuk reboot, lalu terlihat LED yang bertuliskan “Minor, Major dan Critical” mengalami perubahan warna, semula tak berwarna namun sekarang berwarna AMBER.

PRP/RP0/CPU0:ios(config)#install add disk0:/hfr-mini-px.pie-4.2.4

PRP/RP0/CPU0:ios(config)#install activate disk0:hfr-mini-px-4.2.4

Ditunggu beberapa saat, namun si IOS XR belum juga up dan mengalami reboot beberapa kali sambil menunjukan beberapa logs:

Lalu tiba-tiba si chasis diam seperti power-nya OFF. Saya pun mengeceknya dan ternyata LED status di PRP bertuliskan “shutdown”.

setelah googling dan diskusi dengan salah satu teman, bertemulah dengan link berikut:

http://www.cisco.com/c/en/us/td/docs/routers/crs/ec/8_slot/installation/guide/crs8enhig/crs8enhigaircirc.html#pgfId-1088779

di sana dibilang kalau fan tray dengan PID: CRS-8-FANTRAY-B , harus menggunakan IOS XR versi 4.3.2 atau yang lebih baru 🙂
