Cisco CATALYST 2960 - Power over Ethernet Features; Ability to provide power to connected Cisco pre-standard and IEEE 802.3 af-compliant powered devices from Power over Ethernet (PoE)-capable ports if the switch detects that there is no power on the circuit.; Support for IEEE 802.3 at, (PoE+) that increases the available power that can be drawn by powered devices from 15.4 W per port to 30 W per port (Catalyst 2960-S only); Support for Cisco intelligent power management. The powered device and the switch negotiate through power-negotiation CDP messages for an agreed power-consumption level. The negotiation allows a high-power Cisco powered device, which consumes more than 7 W, to operate at its highest power mode. The powered device first boots up in low-power mode, consumes less than 7 W, and negotiates to obtain enough power to operate in high-power mode. The device changes to high-power mode only when it receives confirmation from the switch.

Figure 3-3 Installing the Mounting Screws Under a Desk or Shelf
Step 4 Use a 0.144-inch (3.7 mm) or a #27 drill bit to drill a 1/2-inch (12.7 mm) hole in the three screw
template slots.
Step 5 Insert three screws in the slots on the screw template, and tighten until they touch the top of the screw
template.
Step 6 Remove the screw template from underneath the desk or shelf.
Step 7 Place the switch onto the mounting screws, and slide the switch forward until it locks in place, as shown
in Figure 3-4.
Note We strongly recommend that you allow at least 3 inches (7.6 cm) of clearance around the
ventilation openings to prevent airflow restriction and overheating.
