When working with transceiver modules supporting fiber-to-copper conversion, the SAP-48GBP
uses category-5 straight-through or crossover Ethernet cables when operating at 10/100 Mbps,
and uses category-6 cable (recommended) when operating at 1000 Mbps.
For the appearance and connection of a SAP-48GBP interface cable, see "

SAP-4EXP (RT-SAP-4EXP-H3)
The SAP-4EXP is a 4-port 10 Gbps Ethernet service module. It provides 4 SFP+ ports, all of which feature
Layer 3 routing and high-performance Layer 2 switching. Each port uses a bi-color LED indicating the
running status of the interface. In addition, the SAP-4EXP uses a run LED (RUN) to show the running status
of the module.

Max power consumption
•
Tested
—109 W
•
Theoretical
—150 W
NOTE:
The theoretical max power consumption, greater than the tested max power consumption, is the upper
power consumption threshold defined for the SAP to prevent power module overloading. You must use the
theoretical max power consumption, rather than the tested max power consumption, to calculate the total
power consumption for managing power modules and determining power module numbers.
