+ copper twin-ax technology. At least one 10GbE SFP+ uplink is required to
connect to a C9010 switch.
NOTE: A C1048P can connect to a C9010 switch only through a 10GbE
SFP+ port; a C1048P cannot connect to a C9010 through a
10/100/1000 Mbps RJ-45 port.
CAUTION: ESD damage can occur if the components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when
handling the PE and its components.
WARNING: When working with optical fibres, follow all the warning
labels and always wear eye protection. Never look directly into the end
of a terminated or unterminated fibre or connector as it may cause eye
damage.
To connect to a C9010:
1. Position the SFP+ optic correctly over a port. The optic has a key that
prevents it from being inserted incorrectly.
2. Insert the optic into an SFP+ port until it gently snaps into place.
3. Connect one end of an appropriately connectorized fiber-optic cable
into the port. Connect the other end to an SFP+ connector in a C9010
switch.
Stacking Multiple C1048P Port Extenders
The C1048P supports PE stacking, which allows multiple C1048P units to act
as a single port extender You can stack up to eight C1048P port extenders
using the stack ports located on the back panel.
C1048P stack ports support the Serial Attached SCSI (SAS) protocol and
operate as mini-SAS ports. The C1048P supports stacking only with other
C1048P port extenders. You can connect up to eight C1048Ps together
through the stack ports so that they operate as a single unit with up to 384
front panel ports. The stack operates and is managed as a single entity.
NOTE: If you are installing a stack of C1048Ps, assemble and cable the
stack before powering it up. When you power up a stack for the first
time, the C1048P units receive the provisioned configuration from the
parent C9010. A stack master unit is elected based on the highest MAC
address or highest provisioned priority. The master unit may occupy any
location in the stack. The Master LED on the front panel is illuminated on
the master unit.
