Removing the SFP Module Patch Cable

To remove an SFP module patch cable from the SFP module slot, release the connector, and pull it from the slot.

Replacing the SD Flash Memory Card

Warning Be aware that the SD card contains sensitive and security relevant information, including but not limited to full device configuration information, public and private keys used for SSH and SSL (if those protocols are enabled), device passwords and others. Access to SD cards for any Cisco CGS switch should be limited to authorized personnel.

Step 1 Locate the Secure Digital (SD) flash memory card slot on the cable-side of the switch. Step 2 Use a number 1 Phillips screwdriver to loosen the captive screw (see Figure 2-21).
