CAUTION: You can insert and connect XFP transceivers while the switch is

operating. You can also disconnect and remove XFP transceivers while the

switch is operating. However, inserting or removing the module is not

supported; it can crash or lock up the switch, requiring a reboot.

CAUTION: The CX4 module does not use transceivers. However, you can use

a CX4 cable with an XFP port by inserting a CX4 XFP converter (catalog

name GP- XFP-1CX4) into the slot. An XFP port does not support the use of

the cx4-cable-length command.

Power Up Sequence

There is no power switch. Connecting the switch to either an AC or DC power

source starts the switch. The S50V and S50N switches have both AC (3-prong

plug receptacle) and DC (-48V terminal-type) connections on the back of the

unit. They can use either power source independently or in combination, with

the DC source in a backup mode (except for the 470W DC power supply). You

have three options for providing power to the switch — AC only, DC only, or

using both AC and DC sources. If you select the third choice — AC and DC —

the switch will only use the DC source after the AC source fails.

The rear of the S50N and S50V models have both an auto-sensing 110/220V AC

receptacle and a standard -48V terminal-type DC connector. The rear of an

S50N differs only in the arrangement of the lugs on its DC terminal block. Each

system ships only with the AC power cord.

Dell Force10 recommends re-inspecting your system prior to powering up.

Verify that:

•

The equipment is properly secured to the rack and properly grounded.

•

The equipment rack is properly mounted and grounded.

•

The ambient temperature around the unit (which may be higher than the

room temperature) is within the limits specified for the unit.

•

There is sufficient airflow around the unit.

•

The input circuits are correctly sized for the loads and that sufficient over-

current protection devices are used.
