Recommendations for Cable Management 2 Example switch:admin> tsclockserver LOCL switch:admin> tsclockserver 132.163.135.131 switch:admin> CORRECTING THE TIME ZONE OF A SWITCH If the time of your switch(es) is off by hours (and not minutes), use the following procedure on all switches to set the time zone: 1. Log in as admin. 2. Enter the tsTimeZone - - interactive command. 3. Follow the prompts to select the correct time zone for the switch. Refer to the tsTimeZone command in the Fabric OS Command Reference for more detailed information about the command parameters. 4. Repeat Steps 1 through 3 on all switches for which the time zone needs to be set. This needs to be done only once, because the value is stored in nonvolatile memory. Recommendations for Cable Management Cables can be organized and managed in a variety of ways, such as by using cable channels or patch panels. Following is a list of recommendations: - Plan cable management before installing the switch in a rack. - Leave at least one meter of slack for each port cable. This provides room to remove and replace the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius. ATTENTION A 50-micron cable should not be bent to a radius less than 2 inches under full tensile load and 1.2 inches with no tensile load. Tie wraps are not recommended for optical cables because they are easily overtightened. - If using Brocade ISL Trunking: - It might be useful to group cables by trunking groups. - The cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the Brocade Fabric OS Administrator's Guide. - For easier maintenance, label the fiber-optic cables and record the devices to which they are connected. - Keep LEDs visible by routing port and other cables directly down or otherwise away from the LEDs.
