• Switch connection: Up to three optical fibre cables are connected together through the switches to
connect the devices. Up to two switches can be used.
In the following figure:
1. Some switch vendors require F port (for example, McData ED5000).
2. To set ports, use LUN Management and set port topology to:
• NL port: Fab on, FC-AL
• N port: Fab on, Point-to-Point
Figure 9 Fibre Channel interface switch connection (FL port or F port)
• Extender connection: Channel extenders and switches are used to connect the devices across large
distances.
In the following figure: * To set ports, use LUN Management and set port topology to:
• NL port: Fab on, FC-AL
• N port: Fab on, Point-to-Point

Serial Remote Copy Connections
The following figure shows the TC390 serial remote copy connection configurations. The MCU and RCU of
each TC390 pair must be connected through multimode ESCON cables. For distances greater than 3 km,
single-mode cables up to 20 km in length and IBM 9032/9033 ESCDs and/or 9036 ESCON repeaters
are required. Dedicated ESCON channels may be installed, or existing ESCON channels connected by
ESCDs may be used. The IBM 9032/9033 ESCD supports the extended distance facility (XDF), which uses
single-mode ESCON cables up to 20 km. The IBM 9036 ESCON repeater supports
single-mode-to-single-mode connection or single-mode-to-multimode connection. When TC390 disk arrays
are more than 9 km apart, the XDF connections provided by the ESCDs or ESCON repeaters are required.
TC390 operations can be performed at distances of up to 43 km (26.7 miles) using standard ESCON
