XL-HB14128M HomePNA3.0 Switch User’s Guide

3. Link/Act (E1, E2): Lighting up when the Ethernet link is active, and flashing when there is any data traffic.
4. ID: 7-segment led shows the switch status. Display ‘1’ for OK, or display the other status code of self-diagnosis in
booting.
Connecting the Cables
The HomePNA ‘Terminal’ port (1 to 14) requires standard twisted phone wiring for user attached to the same phone
line via the HomePNA adapter. The HomePNA ‘Line’ port (1 to 14) connects to the PSTN/PABX for your original
phones. The Ethernet port (E1 and E2) is unshielded twisted pair (UTP) 1000Base-T cabling. All 16 ports work as a
standard 16 ports Managed Ethernet switch in the LAN (Local Area Network) environment. See Figure 2 for the detail
cabling of one HomePNA switch XL-HB14128M.
Figure 2 Detail cabling of XL-HB14128M
On each HomePNA ‘Terminal’ (port 1 to 14) you can connect maximal 24 HomePNA 3.0 adaptors (XL-HB128M).
Totally could be used up to 336x XL-HB128M per each switch. For best performance we recommend to use as
maximum of four XL-HB128M units per ‘Terminal’.
Stacking
You can stack more XL-HB14128Ms to accommodate more HomePNA users by cascading XL-HB14128M's Ethernet
port in one MDU/MTU system. For example, connect two or three XL-HB14128M with Ethernet cable from one
switch's port E1 to the next switch's port E2. And cascade their console port together for the MAP Sync Clock to
coordinate all switches. See Figure 3 for the cabling of cascaded HomePNA switches.
