Running SecureCRT in GNS3 using Windows 7

GNS3 uses PuTTY by default to console into devices. I've been using SecureCRT for many years now and it's a very popular terminal emulation software in many companies.

In order to change the console application to SecureCRT in GNS3, you go to Edit > Preferences > Console applications tab. Under Preconfigured commands choose SecureCRT and click Set.

You might need to change the directory of SecureCRT.exe under Console application command if you can't open SecureCRT in GNS3. You can get the location by doing a right-click on SecureCRT (on desktop icon or using search programs) and click Properties.

You can customize the font and background colors. I always choose the Traditional color scheme to get that "Matrix" look and feel.

To edit the session appearance in SecureCRT, go to Options tab > Global Options > General > Default Session > Edit Default Settings.

You can choose the color scheme from the Current color scheme drop-down options > click OK.

Choose Change ALL sessions (no undo) > click OK.

Cisco 3850 Switch Power Supply No Response Issue

I recently ran into a power supply issue on a Cisco 3850 switch. The PSU 1B Sys Pwr status displayed No Response even though the switch detects it and draws 1100 watts of power. Cisco's usual convention for ports and modules starts from right to left but the PSU is different. PSU A is on the LEFT and PSU B is on the RIGHT. I mistakenly pulled PSU 1A so I put it back and reseat PSU 1B instead and status were all good afterwards.
