Power the Base Station

The base station is powered the following ways:
• Power over Ethernet (only IPBS).
• Power over Express Powering Pairs (EPP) and data pairs (only BS3x0)
• By a local power supply.
Note: Do not power the base station using both power supplies. Parallel powering will
not harm the base station but it can disturb the signalling.
4.3.1

Power the IPBS over Ethernet

The IPBS supports Power over Ethernet, IEEE 802.3af, class 2. The IPBS power
consumption is maximum 5W. But according to the PoE standard for class 2 the PoE
power source will allocate 7W to the IPBS. This must be regarded when planning the
powering of the IPBSs so that the power limit of the PoE power source is not exceeded.
The PoE standard supports two ways of feeding the power:
1 Power over the Rx/Tx data pairs.
2 Power over the spare cable pairs.
Both power feed methods are supported in the IPBS, it is also insensitive to change of the
polarity.
4.3.2

Power the BS3x0 over Express Powering Pair (EPP) and data pairs

When a base station is powered remotely via the IPBL, the maximum length between the
base station and the IPBL depends on the supply voltage, the number of twisted pairs used
and the wire size. The length of the cable should never exceed "data-limited" length of
the cable, see
4.3.3

Power the Base Station with a Local Power Supply

Powering the base station with a local power supply can be done using the second data/
power inlet on the base station. The base station can be powered individually by an AC-
adapter. The AC-adapter is provided with an 8-pin RJ45 plug that can be plugged into the
Power Supply jack. For specification see
Note: Only approved power supply according to valid editions of EN/IEC/CSA/UL/AU/NZS
60950 is to be used when the base station is powered by a local power supply.
5 Installation of the IPBL
This section describes how to install the IPBL.
5.1 Install the IPBL
IMPORTANT: To keep the same functionality of the system, do not mix different RPFs,

Core (KRCNB 201) and Worf (KRCNB 30x and BS3x0), on the same IPBL. It
is also recommended for the RFPs to use the same software version.
