module. One empty slot for every 2 values of N
greater than N=2. (i.e. one empty slot for N=3 or
4, two empty slots for N=5 or 6 etc.).
When using the 6NE module in MV3 systems, it
is necessary to map to a time slot, for WAN A, at
least 3 time slots to the right of the physical slot
where the 6NE is installed. WAN B, (if used),
must similarily be mapped 3 slots to the right of
where WAN B is shown. (Please refer to Fig. 24-
3) MV5 does not have these restrictions.
24.4.3 Status Indicators
This module has eleven status indicators as shown
in Figure 24-4. The red/green status LED is green
if the module is functional and red if the module is
non-functional. Top to Bottom & Left to Right,
they are;
Data Errors - A / Data Errors - B
CPU Ready - A / CPU Ready - B
Link Integrity - A / Link Integrity - B
Link Integrity - Port 0 / Link Integrity - Port 1
Link Up - A / Link Up - B
24.5 Acceptance Tests
As noted earlier, we recommend that you initially
install and test the 6NE module in a “test” chassis
(i.e., chassis that are not part of an operating
network). This way, you can quickly perform the
acceptance tests without interfering with a live
network. Either of the following tests will verify
the connectivity of your 6NE network.
24.5.1 Ethernet Ping Test
Ping is a generic tool found in most operating
systems to test network connectivity to a remote
computer. It is a network test, not a 6NE link level
test and can therefore work between any 2
computers, independent of the number of 6NE
modules.
To see how ping works, on a Windows PC, open a
DOS window and type ping/?, this will display the
help screen for the ping command.
A ping command looks like this:
ping 192.168.1.2
Since the originating PC does not have the MAC
address of the PC being pinged, the ping
command forces the originating PC to send a
broadcast ping packet out its Ethernet port over
the entire network, over all 6NE links and down
all LAN segments. Providing the network is
working properly, the PC with the address being
pinged will reply with a ping response packet. The
original PC receives this packet and displays a
response showing the round trip time. The origi-
nating PC will ‘learn’ the MAC address of the
responding PC and thereafter will send nonbroad-
cast ping packets with the MAC address of the
pinged PC.
When testing connectivity over a 6NE network, it
may be beneficial to start with one DS0 channel
and bond more as connectivity is verified.
