Chapter 2 Switch Installation
Installing the Switch
Rack-Mounting
To install the switch in a 19-inch or 24-inch rack (24-inch racks require optional mounting hardware),
follow the instructions described in these procedures:
• Removing Screws from the Switch, page 2-12
• Attaching Brackets to the Catalyst 3750G-24TS Switch, page 2-14
• Attaching Brackets to the Catalyst 3750G Integrated Wireless LAN Controller Switches, page 2-17
• Attaching Brackets to All Other Catalyst 3750 Switches, page 2-18
• Mounting the Switch in a Rack, page 2-24
• Attaching the Cable Guide, page 2-26
Note When you install the switch in a 24-inch rack, an optional bracket kit that is not included with the switch
is required. You can order a kit containing the 24-inch rack-mounting brackets and hardware from Cisco.
For the Catalyst 3750G-24TS switch, order part number RCKMNT-3550-1.5RU=. For the other
Catalyst 3750 switches, order part number RCKMNT-1RU=. The Catalyst 3750G-24WS-S25 and the
3750G-24WS-S50 switch do not support 24-inch rack-mounting.
Removing Screws from the Switch
If you plan to install the switch in a rack, you must first remove the screws in the switch chassis so that
you can attached the mounting brackets.
• Figure 2-9, Figure 2-10, and Figure 2-11 show how to remove the chassis screws in a 1-rack-unit
(RU) switch.
• Figure 2-12 shows how to remove the chassis screws in a 1.5-RU switch.
• Figure 2-13 shows how to remove the chassis screws in a 2-RU switch.
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to
ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest
component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in
the rack.
