www.dell.com | support.dell.com The total PoE power budget for the switch is between 320W and 790W, depending on the power sources available. If the external 470W Redundant Power Supply (catalog # S50-01-PSU-V) from Dell Force10 is attached to the Current Sharing terminal (see Chapter , Installing Backup Power, on page 29), you can use the power-budget command in FTOS to convert the power supply to current-sharing mode to provide up to 790W of PoE. When running SFTOS, use the inlinepower threshold command. Each port can provide a maximum of 15.4W, subject to the power budget, voltage, power priority, and power limit settings. PoE is, by default, enabled globally on a first-come, first-serve basis, until it exceeds the total available power. Alternatively, the switch administrator can use the CLI to allocate power on a per-port and a per-stack-unit basis, with per-port power limits and port prioritization. For a brief introduction in this guide to the PoE commands, see Connecting S50V Ethernet Ports with PoE on page 42. For details, see the PoE Commands sections in the Command Reference and Configuration Guide for your software. Storing Components If you do not install your system and components immediately, Dell Force10 recommends that you properly store the switch and all optional components until you are ready to install them. WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the switch and its accessories. After you remove the original packaging, place the switch and its components on an antistatic surface. Follow these storage guidelines: • Storage temperature should remain constant, in the range from -40° to 158° F (-40°C to 70° C). • Storage humidity should be within 10 to 90% (relative humidity), non-condensing • Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts. • Store in a dust-free environment. Tools Required S-Series switches are shipped fully assembled, encased in foam. A utility knife is useful for cutting the packing tape, and a Phillips #2 screwdriver is required for attaching rack screws, and is also used for making some attachments, including DC cables and rear cover plates. Wear an anti-static guard, as noted above. 16 | Site Preparations

The total PoE power budget for the switch is between 320W and 790W, depending on the power sources
available. If the external 470W Redundant Power Supply (catalog # S50-01-PSU-V) from Dell Force10
is attached to the Current Sharing terminal (see

use the
power-budget
command in FTOS to convert the power supply to current-sharing mode to
provide up to 790W of PoE. When running SFTOS, use the

Storing Components
If you do not install your system and components immediately, Dell Force10 recommends that you
properly store the switch and all optional components until you are ready to install them.
WARNING:
Electrostatic discharge (ESD) damage can occur when components are mishandled. Always
wear an ESD-preventive wrist or heel ground strap when handling the switch and its accessories. After you
remove the original packaging, place the switch and its components on an antistatic surface.
Follow these storage guidelines:
•
Storage temperature should remain constant, in the range from -40° to 158° F (-40°C to 70° C).
•
Storage humidity should be within 10 to 90% (relative humidity), non-condensing
•
