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, 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.
