Installing and removing a 10 Gb SFP+ module
The switch supports the 10 Gb small-form-factor pluggable (SFP+) module and the
1 Gb small-form-factor pluggable (SFP) module. The SFP+ and SFP modules are
laser products that convert electrical signals to optical signals.
For additional information about the location of the switch, the network interface
requirements, and expansion options, see the documentation for your Flex System
chassis.
Notes:
1. The illustrations in this document might differ slightly from your hardware.
2.
While the information in this section describes the 10 Gb small-form-factor
pluggable (SFP+) module, it also applies to the 1 Gb small-form-factor
pluggable (SFP) module.
3. The switch also supports MSA-compliant copper direct-attach cables (DAC), up
to 7 m (23 ft) in length.
Handling an SFP+ module
Before you install an SFP+ module, read the following information:
v The module housing of the SFP+ has an integral guide key that is designed to
prevent you from inserting the module incorrectly.
v
Use minimal pressure when you insert the module into the port. Forcing the
module into the port can cause damage to the module or the module port.
v
You can insert or remove the module while the Flex System chassis is turned on.
v
You must first insert the module into the port before you can connect the cables.
v
You must remove the cable from the SFP+ module before you remove the SFP+
module from the switch.
