D. CONNECT THE ATM SWITCH TO THE CHASSIS AND CP SERVER
11.13 The interface and architecture of the ATM switch types differ. This affects the way the
switch physically connects to the chassis and CP Server, as described in the following sections.
ForeRunner LE155
11.14 The ForeRunner LE155 switch houses three (or four if the expansion slot is populated)
different interfaces, each labeled A-C (or D). Each of these interfaces contains four ports (1-4),
for a total of 12 ports (16 with the expansion slot). Each individual port is then identified by
the interface letter and port number. For example, the third port under Interface B is considered
Port B3.
11.15 The architecture of the ATM Switch allows each interface to function independently.
Using the Element Manager, see the ATM Switch documentation on the Ericsson
CD, you can reset one group of ports without affecting the others. For this reason, use a sepa-
rate interface for each chassis connection when possible. For example, if you have four chassis,
connect the first to Port A1; the second to Port B1; the third to Port C1; and the fourth to Port
A2 (or D1 if populated). When configured this way, you can reset ATM connections almost
entirely on a per-chassis basis. For example, if chassis two has a bad connection but chassis
three is running, you can reset Interface B without bringing down the third chassis.
NOTE:
those provided on the ATM Switch.
11.16 To connect the ForeRunner LE155 switch to the PCMA cards and the CP Server:
1.
2.
NOTE:
compatible operating system (OS) or CP versions. When the CP Server first signs on to a chas-
sis, the chassis sends a version response. If the version is not compatible, the CP Server does
not allow that particular CPU to come online, and message print M5134 is submitted.
ASX-200BX
11.17 The architecture of the ASX-200BX switch allows each interface to function indepen-
dently. Using the ATM Management Interface (AMI), you can reset one group of ports without
affecting the others, see the ATM switch documentation on the Ericsson (Marconi) CD. For
this reason, use a separate interface for each chassis connection when possible. For example, if
you have three chassis, connect the first to Port 1A1; the second to Port 1B1; and the third to
1C1. When configured this way, you can reset ATM connections almost entirely on a per-chas-
sis basis. For example, if chassis two has a bad connection but chassis three is running, you can
reset Interface B without bringing down the third chassis.
NOTE:
as those provided on the ATM switch.

MANUAL VERSION 11.0 – May 2008
The chassis PCMAs must have the same connector types (UTP5, MMF, or SMF) as
Connect CAT5 or MMF cables to the appropriate PCMA card and ATM Switch connec-
tors. Connect each equipment chassis to a different interface on the ATM Switch, if pos-
sible. For more information on the PCMA Groups and how they connect to the Switch,
see page 3-14.
Connect CAT5 or MMF cables to the PCMA card and ATM Adapter card on the CP
Server. If using a redundant system, connect each CP Server to a different interface on
the ATM Switch.
The CP Server is responsible for ensuring the chassis in an ATM system are running
