CSCvf34445 | There were no defects filed with this field notice at the time of publication. |
Certain types of snagless Ethernet cables have protective boots that extend too far forward and above the plastic latching tab.
When this type of cable is installed in Port 1 of any 48-port model of the Cisco Catalyst C3560X or C3750X Series switches, the boot might press and hold the Mode button, which invokes Express Setup and reboots the system. (Reference Figures 1 through 3 for illustrations of the issue.)
Note: This type of boot-cable can partially obscure port LEDs, air vents, and USB ports.

Snagless Ethernet cables were developed many years ago in order to protect the plastic latching tab from becoming snagged, bent, or broken. There are various ways to achieve this goal, but the most common is to hide the tab under a plastic shroud or boot.
Numerous types of snagless cables are available. However, most are designed in such a way that the protective device is less prominent and/or held more tightly to the tab, which prevents the aforementioned drawbacks.
When Express Setup is inadvertently invoked by the protective boot of the cable, these messages are seen in the syslog:
%SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram %SYS-5-RELOAD: Reload requested by Hulc LED Process. Reload Reason: Reason unspecified.
After this occurs, the device resets. The startup configuration is erased once the device enters Express Setup.
There are three options used in order to address this problem:
3750(config)# no setup express
