Table 31 (Page 2 of	2). Dual Fiber Repeater Module LED Descriptions

LED Name		Color	State	Description

RI/RO		Green	On	Trunk enabled and operating

			Off	Trunk disabled.

			Blinking	Trunk enabled but not
				operating normally

JA1 and JA2		Green	On	JADC card installed and
				operating normally

			Off	JADC card not installed

			Blinking	JADC card failed diagnostics

Port Status		Green	On	Port enabled and operating
				normally on the ring

			Off	Port disabled

			1 blink	Port enabled, no phantom

Figure 114 shows the side view of the dual fiber repeater module. As can be seen, in addition to the 11 isolated segments and the mounting for one T-MAC, there is an 8-position DIP switch located on the module. These DIP switches are used in the absence of an installed management module in the 8260. However, if a management module is installed in your 8260, the setting of these DIP switches will be ignored unless ″DIP_CONFIGURATION″ is enabled for DMM. For more information, please refer to 4.2.4.4, ª Configuring DMM Deviceº on

page 50.

Figure 114. Dual Fiber Repeater Module Side View

The DIP switch settings on this module are identical to those of the 18-port active per-port switching module which is described in 9.3.1, ªConfiguring the 18-Port Active Per-Port Switching Moduleº on page 177.
