INSTALLATION
This chapter describes the installation procedure for your switch.
Packing List
Your package should come with the equipment listed below,
•One HomePNA Switch XL-HB14128M
•One AC Power Cord
•One RS-232 Console Cable (DB9-MiniDin8)
•One Cascaded Console Cable (MiniDin8-MiniDin8)
•One Cascaded Ethernet CAT-5 Cable

Front Panel
See the following Figure 1.
Figure 1 Front panel of XL-HB14128M
Connectors
1. 1 to 14: Fourteen HomePNA ports with dual-row RJ-45 connector labeled ‘1’ to ‘14’. Each HomePNA port has one
‘Line’ connector (upper row) and one ‘Terminal’ connector (bottom row).
2. E1, E2: Two Gigabit Ethernet ports are used to cascade with other XL-HB14128M or standard Ethernet Switch/Hub.
See the following section “Connecting the Cables” in this Chapter.
3. Console IN: The console IN port may connect to the serial COM port of PC for local configuration by the RS-232
Console Cable. See “Connecting the Cables”.
4. Console OUT: If you stack more XL-HB14128M in one MDU/MTU (Multiple Dwelling Unit/Multiple Tenant Unit)
system, one XL-HB14128M will be selected to output the MAP Sync Clock. All other switches will synchronize
to the same MAP Sync Clock input from Console IN port. It is necessary to connect the selected switch Console
OUT port to all other switches Console IN port in order to coordinate all the transmissions in HomePNA 3.0
Synchronous MAC protocol. Cascaded Console Cable is used to connect the console IN/OUT port through a lot
of switches in one MDU/MTU system. See “Connecting the Cables”.
NOTE: HomePNA 3.0 always adopt the Synchronous MAC protocol layer in MDU/MTD system to eliminate
Cross-Talk effect in a bundle of multi telephone wiring. It is crucial to MDU/MTD system.
LED Indicators
1. PWR: Lighting up when power on.
2. Link/Act (1 to 14): Each led represents the responding HomePNA port. Flashing when there is any data traffic.

XL-HB14128M HomePNA3.0 Switch User’s Guide
6
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.

XL-HB14128M HomePNA3.0 Switch User’s Guide

Figure 3 Cabling of more XL-HB14128M in single MDU/MTU system
The other way to stack more XL-HB14128Ms is applying the Gigabit Ethernet Switch. This connection can achieve
the maximum available bandwidth utilization for Gigabit rate up-link trunk. Note that port E1 is the up-link trunk of
XL-HB14128M. Also connect their console port together for the MAP Sync Clock to synchronize all switches. See the
following Figure 4.
Figure 4. Cabling of more XL-HB14128M by Ethernet Switch
Note that in the stacking switch architecture as Figure 3/Figure 4, the HomePNA switch ‘#1’ will generate and output
the MAP Sync Clock for all other switches. You can cascade their console port by Cascaded Console Cable as Figure
3; or you can connect all the console port together as Figure 4. You may re-wire the console line in Figure 4 to the
wiring way in Figure 3(Change the green wiring).

XL-HB14128M HomePNA3.0 Switch User’s Guide
8
To configure HomePNA switch ‘#2’ or ‘#3’ locally, unplug the cable from the console IN port and connect RS-232
Console Cable to PC for local configuration. Plug in the previous cable after you have finished the configuration.
The remote configuration function by Web browser or Telnet program can work with switch ‘#1’ ,‘#2’ and ‘#3’ in
Figure3/Figure4 without re-cabling.
NOTE: The 7-segment led shows the switch status code from ‘1’,‘2’,… to ‘9’. The dot (•) symbol shows on the
7-segment's right-bottom corner indicates that the code will plus 10. The code 10 will show ‘0.’, and 11 will be ‘1.’.
The 19 is ‘9.’. This led should always be ‘1’ after successfully power up.
Verification
After you have finished the installation, you should use the Web Browser to access the switch through Ethernet link
remotely or through Console link locally to verify the installation is completed. (See next Chapter for details).
NOTE: The factory default Port-Based VLAN setting doesn't allow the user to access the switch XL-HB14128M
internal Web Server remotely through port E2. Port E2 is designed to cascade the main Gigabit Ethernet Trunk. You
may connect to port E1 of XL-HB14128M with Ethernet UTP cable to your PC by default IP address
‘192.168.0.1’ .
CONFIGURATION
This chapter describes the configuration procedure for your switch.
Configuration Methods
To access and configure your switch, choose one the following methods:
♦Use Web Browser
♦Use Telnet Program
♦Use RS-232 Console Cable with a terminal emulation program as HyperTerminal in Windows.
Using Browser or Telnet Program is considered as Remote Configuration. RS-232 Console Cable connection is
called Local Configuration.
Use Web Browser
Web browser is the easiest tool to configure the switch. The factory default IP address of XL-HB14128M is
‘192.168.0.1’ and the default subnet mask is ‘255.255.255.0’. To access the switch with default IP, your PC should be
within the same IP network as the switch XL-HB14128M. That is, your PC's IP address should be as "192.168.0.xxx".
For instance, you may connect one PC with the switch directly by one Ethernet cable between your PC's Ethernet
adapter and switch's port E1. Also configures your PC's TCP/IP setting to fixed IP as "192.168.0.xxx", subnet mask as
"255.255.255.0", disable DHCP option. Make your PC and the switch within the same "192.168.0.xxx" network. Type
in 192.168.0.1 in your browser’s website navigating field, as the following,

The switch will prompt you a window for username and password authorization. The factory default Password for
XL-HB14128M is ‘root’. Please change it to a more secured password after you login successfully. Here shows the
main configuration menus on the browser.
The main window contains the left sub-window for the items to be configured, and the right sub-window displays the
contents for the selected item. Click your mouse on the item in the left window will pop out the corresponding
item-window in the right side. Click on the ‘Apply’ button (or ‘OK’ button in some screens) will submit your new

setting into the switch and will take effect immediately.
Upgrade
Browse to locate the new firmware or driver file for the upgrade item, and click ‘Upgrade’ button to proceed,
Switch Firmware
Upgrade the XL-HB14128M management firmware—the OS of XL-HB14128M. The switch will reboot after
upgrade.
Switch HomePNA Driver
Upgrade all XL-HB14128M HomePNA ports driver for the onboard HomePNA Chipset device, may treat it as device
driver for XL-HB14128M. The switch will reboot after upgrade.
HomePNA Driver for EP -- Endpoint
This is the first step in the 2 stages procedure for EP driver upgrade:
1. Upload EP HomePNA driver onto XL-HB14128M internal RAM.
2. Wait to upgrade the selected EP by XL-HB14128M itself.
The second step can be accomplished by the following “EP Management” function. The EP HomePNA driver stored in
XL-HB14128M’s RAM will vanish after rebooting XL-HB14128M.
NOTE: Work for HomePNA Ethernet Bridge only (as XL-HB128M), can’t work for USB adapter (as XL-HU128M).
Endpoint (EP) Management
Click the digit denoted ‘Port number’ on the web page will list all connected EP’s at current port. Here the ‘NA’ means
‘EP HomePNA driver’ is not available yet in XL-HB14128M RAM – you need to upload it onto the XL-HB14128M
first by ‘Upgrade’ function.

XL-HB14128M HomePNA3.0 Switch User’s Guide
11
After uploading the driver into XL-HB14128M, you may designate the targeted one or multiple EP’s for driver
upgrade.
Crosstalk
A bundle of phone wires may induce crosstalk noise to affect each other. Here we show the example for the strong
crosstalk effect between Port 1 and Port 2. XL-HB14128M can aware of this by showing ‘Crosstalk’ words in
‘Remark’ field. As the following,

XL-HB14128M HomePNA3.0 Switch User’s Guide
12
Port 1 and Port 2 will share the bandwidth and may have poor performance in such environment.
Use Telnet Program
Any popular Telnet client could use to configure the switch remotely. For example, run Windows built-in Telnet to
configure the switch.

XL-HB14128M HomePNA3.0 Switch User’s Guide
13
Note that Telnet connection will be terminated automatically if the telnet client doesn’t input any command for 5
minutes; i.e. the console idle timer is 5 minutes.
Use RS-232 Console Cable
To configure your XL-HB14128M switch by local console, do the following:
1. Connect ‘Console Cable’ to front panel Console ‘IN’ connector and then connect the cable to your PC serial port, as
COM1 or COM2.
2. Run a terminal emulation program as HyperTerminal in Windows. Its serial communication parameters should be
set to 115200bps baud rate, none parity bit, 8 data bit, one stop bit and none flow-control. As the following:

ADVANCED FEATURES
This chapter describes the advanced features offered by your switch.
Port-Based VLAN
The main purpose of VLAN is security, to prevent HomePNA user to access each other directly in the switch system.
Only the ports within the same VLAN group can access each other directly.
Default VLAN Configuration
Refer to Figure 3 in Chapter 2, the cascaded Ethernet link acts as a traffic trunk to aggregate all HomePNA port traffic.
The straightforward VLAN configuration should let each HomePNA port (1 to 14) can communicate with the trunk for
LAN/WAN connectivity, but can't communicate with each other directly. In this configuration, Port E1 acts as Trunk
Link port; Port E2 gathers the traffic from other cascaded switch Up-Link port. The following figure shows the data
flow of default Port-Based VLAN in XL-HB14128M,
The default Port-Based VLAN configuration in the switch XL-HB14128M allows each HomePNA user to group with
port E1 only. For each HomePNA user, to access the main Ethernet trunk E1 is allowed, to access other user (port 1 to
port 14, cascaded users on port E2) is forbidden. HomePNA port (1 to 14) and port E2 aren't within the same VLAN
group. Only port 1 to port 14 and port E1 are allowed to access XL-HB14128M for Remote Configuration.
Close VLAN
If you wish to get ride of the VLAN restriction, users locate in the same LAN can access each other freely and make the
switch work as a standard switch. Adopt Tag VLAN mode and set each port with the same VID.
Tag VLAN
Please refer 802.1Q for Tag VID operation and 802.1P for Tag Priority operation. The switch can accept and forward
tagged packet with the matched VID, it can also tag the untagged packet with default VID and Priority.
Each HomePNA port (1 to 14) should be assigned a unique VID. Packets from port E1/E2 trunk with the matched VID
19

XL-HB14128M HomePNA3.0 Switch User’s Guide
can be forwarded to the correct destined HomePNA port. Terminals attached on port 1 to port 14 should be able to
receive tagged/untagged packet and can transmit tagged/untagged packet.
NOTE: The connection may be terminated abnormally while Tag VLAN is being turned on and the terminal (PC) can't
recognize/receive tagged packets, especially while you configure the VID/Priority setting on port E1.
Egress Action Rules
‘Action’ will take effect while packets outgoing from each port of XL-HB14128M,
1. Tag: Untagged packets will be tagged with each default VID and Priority when they go out.
2. UnTag: Tagged packets will be forced to get rid of Tag, become untagged packet when they go out.
3. Pass: Either tagged or untagged packets pass through unchanged.
SNMP
SNMP Agent inside XL-HB14128M will handle request from SNMP Manager. The agent supports standard SNMP
operations as ‘SET’, ‘GET’ and ‘TRAP’.
XL-HB14128M SNMP is setting to read-only mode by default. You need to specify the Read/Write Community
Name into switch before any SNMP ‘SET’ operation can work. Default setting will only allow agent to monitor the
switch and report the requested SNMP data to SNMP manager.
You may need the accompanying proprietary MIB file for some popular SNMP/MIB manager software to manage the
switch system. Or to integrate the XL-HB14128M switch system into your original SNMP management system by this
specific MIB file.
Each SNMP manager must indicate the name of the community it belongs in all ‘GET’, ‘SET’ and ‘TRAP’ operations.
The community name could be unique to allow set of SNMP managers to access to the agent. The default ‘GET’ and
‘TRAP’ community name of XL-HB14128M is ‘public’.
Rate Control
You may impose the restriction of maximum available data rate on HomePNA port for either upstream or downstream
traffic. Rate control disabled by default, and each port could have the maximum possible data rate.
QoS
Quality of Service is enforced by assigning each incoming packet with a predefined priority value. Packet with higher
priority should be processed as soon as possible (fast in, fast out). In shortage of buffers, some low priority packets
should be discarded to smooth the high priority traffic flow. Higher priority traffic will have higher data rate and lower
possibility of discarding.
The numbering priority value ranges from 0 to 7, and 7 represents the highest priority level. XL-HB14128M supports
priority scheme as Port-Based, 802.1P, IP TOS and TCP/UDP protocol.
Priority in Downstream
There are 4 priority queues for upstream packet. Packet with priority value 0 or 1 goes to the same queue, denoted as
Q0. Q1 has priority value 2 and 3, Q2 has priority value 4 and 5, and Q3 has priority value 6 and 7. Totally 4 level of
service are provided. Q3 will always be the first one to service, i.e. packets reside in Q3 will be send out first. Packets
in Q0 will be discarded first in congestion situation since it is classified as less important.
