Page 10: Hardware Description
The LPB2910A, LPB2926A, and LPB2952A switches support two or four Small Form Factor Pluggable (SFP) transceiver slots. The LPB2910A shares two SFP slots with RJ-45 ports 9 and 10. The LPB2926A shares two SFP slots with RJ-45 ports 25 and 26. If an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled. -

Devices connected to the switch can be powered over the twisted-pair cable that links the devices to the switch. A powered device (PD) provides power over the extra wires on the RJ-45 connector and cables. The LPB2910A, LPB2926A, and LPB2952A support PoE (802.3af) and PoE+ (802.3at) up to 30 W per port. 724-746-5500 | blackbox.com... -
Page 16: Network Planning
Chapter 3: Network Planning 3. Network Planning 3.1 Introduction to Switching A network switch allows simultaneous transmission of multiple packets; it can partition a network more efficiently than bridges or routers. The switch is one of the most important devices for today’s networking technology. When performance bottlenecks are caused by congestion at the network access point such as file server, the device can be connected directly to a switched port. -

Then, before beginning the installation, be sure you have all other necessary installation equipment. WARNING: The SFP transceivers are Class 1 laser devices. -
Page 19: Installing An Optional Sfp Transceiver
You can install or remove an SFP from an SFP slot without powering off the switch. Use only compatible SFPs. NOTE: On the LPB2910A and LPB2926A, the SFP slots are shared with the two 10/100/1000BASE-T RJ-45 ports. If an SFP is installed in a slot, the associated RJ-45 port is disabled and cannot be used. -
