HARDWARE INSTALLATION
Prior to installing in a daisy-chain, the address of each TAP-100-2X16 must be set either individually
or as a group — as described in the control pull-down section of this hardware guide.
NOTE
Daisy-chaining capability is limited to four 2x16 switches, yielding access to as many as 64 insert ports.
The typical installation described below focuses on the TAP-100-2X16 unit configuration shown on
the following page in
Figure 14
. To connect between multiple TAP-100-2X16s and individual network
links, refer to the steps below:
1. Connect the DB9 male lead (labeled
A
) to the
COM 1
port of network appliance
A
as shown on
the previous page in
Figure 13
. Remove the DB9 male lead (labeled
B
) tie-wrap to make the entire
lead length available for installation. Connect the DB9 male lead (labeled
B
) to the
COM 1
port of
network appliance
B
.
2. Connect the
LINK
port of the first TAP-100-2X16 unit to the
CONTROL
port of the second TAP-
100-2X16 unit using a DRL448-6 cable. Any subsequent daisy-chained TAP-100-2X16 unit has the
LINK
port connected to the
CONTROL
port of the next TAP-100-2X16 unit using a DRL448-6 cable.
3: Connect the top
TAP A
port to one of the network appliance’s Network Interface Cards (NICs)
using a DRL366-3 tap cable. The selected
INLINE
port data is output on pins 3 and 6 of the
top
TAP A
port.
4. Connect the bottom
TAP A
port to the other NIC of the same network appliance using a
DRL366X-3 cross-over tap cable. The selected
INLINE
port data is output on pins 1 and 2
of the bottom
TAP A
port.
5. Connect the top
TAP B
port to one of the Network Interface Cards (NICs) of the other
network appliance using a DRL366-3 tap cable. The selected
INLINE
port data is output
on pins 3 and 6 of the top
TAP B
port.
6. Connect the bottom
TAP B
port to the other NIC on the same network appliance using
a DRL366X-3 cross-over tap cable. The selected
INLINE
port data is output on pins 1 and 2
of the bottom
TAP B
port.
7. Any subsequent daisy-chained TAP-100-2X16 units have their top
DAISY A
and
B
ports and
bottom
DAISY A
and
B
ports connected to the top
TAP A
and
B
ports and bottom
TAP A
and
B
ports, respectively, of the next TAP-100-2X16 unit using DRL366-3 tap cables for all connections.
8. Connect network cables to the
1–16
ports on the desired TAP-100-2X16 unit.
IMPORTANT
100BASE-T has a history of auto-negotiation problems, primarily because there are two standards; negotiation
can be ambiguous at certain cable lengths. Most NICs do support auto-negotiation, but in many cases, they do
not negotiate very well, if at all. If the network device connected to the TAP-100-2X16 unit
1–16
port upper
connector fails to auto-negotiate, then a cross-over cable must be used to complete the upper port connection.
IMPORTANT
Do not exceed 90 meters network segment length for a single TAP-100-2X16 unit installation and 80 meters
network segment length for subsequent daisy-chain TAP-100-2X16 unit installations.
