4.310 BASE-T Connection Procedure

The pattern for 10 BASE-T cable connections may vary, depending on the system configuration (such as number of IMG stacks or the mounting location/number of the FCH/HUB cards, etc.). According to your system configuration, connect necessary Ethernet cables:

4.3.1Procedure for 1-IMG System

If your system is 1-IMG type, the 10 BASE-T connection should use either of the following cables:

1.Cable unit specified as SR1201 ETIF CAU-n

2.Cables, other than those of SR1201 ETIF CAU-n, that are provided by the user

Based on the cable type, perform the following:

4.3.2When using cable unit SR1201 ETIF CAU-n

1.Referring to any of Figure 4-13through Figure 4-15, connect the 10 BASE-T straight cables, be- tween the LANI (PZ-PC19) and HUB (PA-M96) cards, and between the HUB and FCH (PA- FCHA) cards. If the HUB is in a dual configuration, also connect the 10 BASE-T cross cable be- tween HUB#0 and HUB#1.

When dual LANIs are used in both Slot 00 and 03 of CPR#0/CPR#1, be sure to use at least two HUB cards. Use one HUB for the internal LANI (in Slot 00) and use the other HUB for external LANI (in Slot 03, available for Series 7300 Release 3 software or later). If FCH is also in a dual configuration, the 10 BASE-T cross connection between the two HUBs is not required.

2.If your system needs more FCH (PA-FCHA) and/or HUB (PA-M96) cards, provide the required Ethernet connection(s) for the added card(s) using the following cables:

•When adding FCH card in PIM0: UTP CTG5 ST CA-D

•When adding HUB card in PIM0: UTP CTG5 CRS CA-D

•When adding FCH card in PIM1: UTP CTG5 ST CA-K

•When adding HUB card in PIM1: UTP CTG5 CRS CA-K

•When adding FCH card in PIM2: UTP CTG5 ST CA-M

•When adding HUB card in PIM2: UTP CTG5 CRS CA-M

•When adding FCH card in PIM3: UTP CTG5 ST CA-N

•When adding HUB card in PIM3: UTP CTG5 CRS CA-N

Note: The cables, cited above and used in Figure 4-13through Figure 4-15, are for the 1-IMG system only (not available in the 4-IMG/IMX-U system).
