Chapter 1 Overview
2 Cajun P118 Installation Guide
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.
