Chapter 1
Overview
ꢀDescription
ꢀThe Cajun P118SX and P118LX are part of the Cajun P110 family of switches. The
Cajun P110 family is composed of high-performance stackable switches which may be
used singly or stacked in any combination.
ꢀThe Cajun P118 has eight Ethernet/Fast Ethernet (10/100BASE-T) ports and two
Gigabit Ethernet (1000BASE-X) ports. The 10/100 Mbps ports are typically used for
workgroup connectivity, while the two 1000 Mbps ports can be used as full duplex
uplinks to a Cajun M400, P550, M770 Switch or another Cajun P110 switch or to any
other Gigabit Ethernet switch.
ꢀThe Giga Ethernet ports comply with the IEEE 802.3x Flow Control and IEEE
802.1Q for Tagging Mode standards. All 10/100 Mbps ports can run at full or half
duplex Ethernet. A redundant power supply may be used for enhanced fault tolerance.
ꢀThe Cajun P118 can operate standalone or as part of a stack. A stack can be made up of
any combination of two, three or four Cajun P110 switches, and up 32,000 MAC
addresses per stack are supported. A stack requires a Cajun P110 NMA to link the
switches. The units are physically linked using the Exoplane™.
ꢀ
ꢀNote: You need to install a Cajun P110 NMA in the P118SX and P118LX switches in
order to operate them in stand-alone mode.
ꢀ
ꢀ
ꢀThe Cajun P118 can use an advanced flow control mechanism to eliminate packet loss.
An automatic fairness mechanism ensures that all ports gain fair access to the Exoplane
even at very high network utilization. Congestion management works both on full and
half duplex ports, and ensures no packet loss should the buffers become saturated
during peak load conditions.
ꢀA redundant power supply (Cajun P110 BUPS) may be used for additional fault
tolerance.
ꢀThe Cajun P118 switch is manageable under CajunView,™ Lucent’s family of SNMP
network management systems, or any other SNMP-based management system, and
may be monitored using Lucent’s SMONMaster™ Switch Monitoring Application.
ꢀ
ꢀNote: The P118SX and P118LX switches are identical except that the P118LX
module has single-mode fiber ports. Therefore this Installation Guide will only refer
to the Cajun P118 unless there are differences in the operation of the switches.

Installation
Installing the Cajun P118
The procedure for getting the Cajun P118 up and running depends on whether the
switch is to operate standalone or as part of a stack.
First, attach the adhesive rubber legs to the base of the Cajun P110 switch. If the
switch is to be rack mounted, do not attach the legs.
Standalone Operation - Plug ‘n’ Play
Getting the Cajun P110 switch working is quick and easy:
1.ꢀ Connect the power cable to the switch.
2.ꢀ Connect the cables to the front panel ports.
Note: If you are operating the Cajun P118 in stand-alone mode, you must insert a
Cajun P110 NMA agent. Please refer to the Cajun P110 NMA Installation Guide for
details..
3.ꢀ The switch is now fully operational. By default, all 10/100 ports will operate in half
duplex mode.
Stacking Operation
If you are using the Cajun P118 as part of a stack, you only need one Cajun P110 NMA
for the entire stack.
œꢀ If there is a Cajun P110 NMA already in the stack then ensure it is in the topmost
Cajun P110 switch and remove the additional NMA.
œꢀ If there is no NMA in the stack then place the Cajun P118 at the top of the stack.
To check what software version you have, see the agent configuration window in
MultiMan (on UNIX) or Cajun P110 Manager (on Windows), or see the setup main
menu of the Cajun P110 NMA.
1.ꢀ Before adding a switch to the Cajun P110 stack, turn off the main power to the
stack, by individually switching off each hub
2.ꢀ Place the Cajun P110 NMA in the top switch of the stack
3.ꢀ If the Cajun P110 NMA contains agent software version 8.6 or higher, go to
step 5.
4.ꢀ If the Cajun P110 NMA does not contain the agent software version 8.6, you
should perform a software download of the latest version. The software is on the
diskette that came with the Cajun P118. Download is performed via TFTP using a
Terminal console or via the timed Download application from your management
station– details can be found in the Cajun P110 NMA installation Guide.
5.ꢀ Place the Cajun P118 switch in the stack. The Cajun P110 NMA must be in the
top switch of the stack.
ꢀ
To ensure proper ventilation, ensure that all empty Cajun P110 NMA slots in the
stack are closed.

Installation
6.ꢀ Connect Cajun P110 switches using the Exoplane cables, as shown in Figure 2. A
switch connects to its upper neighbor through two Exoplane cable, and to its lower
neighbor through another two Exoplane cables. Make sure you securely fasten the
cables to the connectors.
Cabling Requirements:
œꢀ For correct operation, the Cajun P110 Exoplane must be fully connected, with all
units powered up. In case units are stacked, the Cajun P110 NMA must be
installed and connected to the Exoplane.
Failure to observe this requirement will cause the Cajun P110 units to block all
traffic on attached stations and segments.
œꢀ When using the Cajun P114T or Cajun P114F in the stack, make sure all switches
in the stack are connected using Exoplane cables. Extra cables can be ordered
from your local Lucent representative.
Figure 2
Rear view of a Cajun P110 switch stack, showing how the switches are linked via
the Exoplane cables. A Cajun P110 NMA resides in the uppermost switch.
7.ꢀ Two terminators are supplied with the Cajun P110 NMA. Insert the two
terminators into the lowest two connectors at the bottom of the stack, as shown in
Figure 2.
8.ꢀ Turn on the mains power to the stack, by individually switching on each hub.
9.ꢀ Connect the cables to the front panel ports.

Rack Mounting
Cajun P110 switches slot into a standard 19 inch rack.
Remove the rubber legs from the base of any switch that is to be rack mounted.
Place the switches in the rack, and then connect the Exoplane, as follows:
1.ꢀ Snap open the ends of the front panel to reveal the fixing holes.
2.ꢀ Slot the switch into the rack. Insert the switches into the rack so that the switches
in a logical stack lie directly on top of each other. Ensure that the Cajun P110
screw holes are aligned with the rack hole positions exactly as shown in figure 3.
Stacking them in this way will allow the switches to be easily connected using the
Exoplane cables.
3.ꢀ Secure the switch in the rack using the screws. Use one screw on each side. Do not
overtighten the screws to avoid damaging the plastic.
4.ꢀ Connect the Exoplane cables, as described above, and as illustrated in Figure 2.
5.ꢀ Snap closed the hinged ends of the front panel.
