Version of NE40-8 = 8011v300r002c01b551usr.bin.
As Slave SRU got faulty so we need to change the faulty Slave SRU.
So we Insert new SRU card on Slave port of NE40-8, and after Ctrl+B we enter into boot menu, I select all the parameters but when i transfer file from laptop to Slave SRU it fails and message was Loading...........Loading Failed
After I plugged-in New SRU card into NE40-8 and I enter Ctrl+B, enter into boot menu. Select the required parameters and plugged-in Lan cable into ethernet port of New SRU. but when i transfer version file it fails.
I try this by checking the Lan Cable through Tester but find it ok,
I connect the LAN cable with the Master SRU and find it ok.
I again connect the Lan cable into New SRU card and i find that it shows connection at 10Mbps.
So i plugged-out the New SRU, insert Lan cable and serial port into New SRU and than Plugged-In the NEW SRU into NE40-8. This time it shows connectivity at 100 Mbps.
This time when i transfer a version file it went successful.
The root cause of this problem is that , connectivity b/w NE40-8 New SRU and Laptop is established at the speed of 10Mbps which was not correct. And the reason of this is that SRU completes it boot process and we set the required parameter on boot menu, and than insert LAN cable into SRU ethernet port. That's why it shows connectivity b/w NE40 and laptop at 10Mbps.
Solution of this is that Connect LAN cable into SRU and then Insert SRU into NE40-8.
