Chapter 12: Removing the Switch WARNING: Because of the switch's size and weight, we require the use of a mechanical lift to remove the switch. NOTE: If you are removing more than one switch in a rack, remove the first switch from the top of the rack. Before removing a J-EX8216 switch from a rack: • Ensure that the rack is stable and secured to the building. • Ensure that there is enough space to place the removed switch in its new location and along the path to the new location. • Read "General Safety Guidelines and Warnings for J-EX Series Switches" on page 201, with particular attention to "Chassis Lifting Guidelines for J-EX8200 Switches" on page 214. • Ensure that the switch has been safely powered off (see "Powering Off a J-EX8200 Switch" on page 151) and that you have unplugged (disconnected) the power cords or cables from the power supplies. • Ensure that you have disconnected any cables or wires attached to the switch ports, the console and management ports, and the protective earthing terminals. Ensure that you have the following parts and tools available to remove the switch: • A mechanical lift • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws • If you installed the switch with square-hole cage nuts, a flat-blade (-) screwdriver to remove the cage nuts To remove the switch using a lift (see Figure 70 on page 155): 1. Use the appropriate Phillips (+) screwdriver to remove the mounting screws-and washers if you installed the switch with cage nuts-that attach the chassis front-mounting brackets to the rack. 2. Place the removed screws in a labeled bag. You will need them when you reinstall the chassis. 3. Move the lift to the rack and position it so that its platform is centered about 0.5 in. (1.27 cm) below the bottom of the switch chassis and as close to it as possible. 4. Carefully slide the switch from the adjustable mounting brackets attached to the rack onto the lift. 5. If you installed the switch with cage nuts: a. Remove the cage nuts from the rack. 153
