Attach a Ground Cable to the System

CAUTION: To prevent electrical shock, make sure the switch is grounded

properly. If you do not ground your equipment correctly, excessive emissions

can result. Use a qualified electrician to ensure that the power cables meet

your local electrical requirements.

NOTE: The rack installation ears are not suitable for grounding.

CAUTION: Grounding conductors must be made of copper. Do not use

aluminum conductors.

NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping.

Bring any un-plated mating surfaces to a shiny finish, and coat with an anti-oxidant

prior to mating. Plated mating surfaces must be clean and free from contamination.

Connect the grounding cable to the FG terminal first (located on the PSU side of

the chassis), then connect the opposite end to the appropriate grounding point at

your site to ensure an adequate unit ground.

Install the SFP and XFP Optics

The S25 chassis have four receptacles on the I/O side that accommodate

10/100/1000 SFP optical transceivers. Additionally, the S25 has bays on the

PSU side that accommodate optional CX4 or XFP modules.

A 10GbE module contains two ports. 10GbE modules should only be inserted or

removed when the switch is powered down.

SFP and XFP transceivers can be inserted or removed while the switch is

running.

CAUTION: Before connecting a transceiver to a source, check the receive

power of the transceiver with an optical power meter. Generally, Dell Force10

specified optics are not to be subjected to receive power higher than that

stipulated by the optic specification. If the optic is exposed to optical power in

excess of the specification, there is a high likelihood that it will be damaged.

Installing SFPs

NOTE: When a copper SFP2 module with catalog number GP-SFP2-1T is used in

the S25P switch, the SFP speed can be manually set with the speed command.

When the speed is set to 10 or 100 Mbps, the duplex command can also be

executed.
