before connecting the catalyst 3750 switches in a stack, observe these planning considerations:

    1?size of the switch. for switch dimensions, go to appendix a, “technical specifications.”?the catalyst 3750-24ts, 3750g-24ts, and 3750-48ts switches are the same depth, and the catalyst 3750g-12s and 3750g-24t switches are deeper than the other switches. stacking switches of the same size together will make it easier to cable the switches.

    2?length of cable. depending on the configurations you have, you might need different sized cables. if you don't specify the length of the stackwise cable, the 0.5-meter cable is supplied by default. if you require the 1-meter cable or 3-meter cable, you can order it from your cisco supplier. for cable numbers, see the "stackwise ports"?section on page 2-15. the "recommended cabling configurations"?section on page 3-15 provides examples of recommended configurations.

    3?access to the rear ports for unrestricted cabling.

    make sure that there is access to the rear of the rack if you are planning to stack the switches. if you do not have access to the rear panel, make sure you cable the switches before you rack-mount them.

    4?for concepts and procedures to manage switch stacks, refer to the switch software configuration guide.
