LampSite Installation Guide 5 Installing a pRRU 5.7.6 Installing an Ethernet Cable This section describes how to install an Ethernet cable. Prerequisites l Ethernet cables are not delivered, and they must be prepared onsite. You need to use a network cable tester to test the Ethernet cable connection. l Cables of Category 5e (enhanced) or higher specification is used for connecting the RHUB and pRRU.
LampSite Installation Guide 5 Installing a pRRU 3. Connect the RJ45 connector at the other end of the Ethernet cable to the transmission port of the AC based on the engineering design, as shown in Figure 5-39.
