Chassis.bk : CHAPTER3 Page 4 Monday, February 10, 1997 1:11 PM 3-4 CHAPTER 3: INSTALLING MODULES INTO THE MSH CHASSIS ■ Resilient links can be set up. See Figure 3-2 below. A resilient link consists of a main port and a stand-by port which are both set up locally via the display panel or remotely via a Network Manager. The main port is the normally operational port; however, if a fault occurs on the link and data cannot be passed over it, the stand-by port will automatically take over. .
Chassis.bk : CHAPTER3 Page 5 Monday, February 10, 1997 1:11 PM Introduction 3-5 Partitioning of a segment from the rest of the network will occur if the module detects thirty-two consecutive collisions on a segment or if it detects a single collision of between 1,000 and 30,000 bit times. Once a segment has been partitioned, the module will pass network traffic onto the segment; but will not accept anything from the segment for transmission to the rest of the network.
Chassis.bk : CHAPTER3 Page 6 Monday, February 10, 1997 1:11 PM 3-6 CHAPTER 3: INSTALLING MODULES INTO THE MSH CHASSIS ■ ■ Firstly, each frame is examined for the destination address, and passed intact to the port associated with that address. For 10Base-T, fiber or AUI, this is equivalent to passing direct to the addressed device. Every other port transmits a frame of the same length and network timing but with randomized bits: this is undecipherable. No extra delays are introduced.

Chassis.bk : APPENDC Page 1 Monday, February 10, 1997 1:11 PM MSH POWER CONSUMPTION LIMITS C Calculating Power Consumption It is important that you calculate the total power consumption and total current consumption required by the LinkBuilder MSH chassis and the modules that you intend to install in the MSH chassis. Only by calculating these values can you be sure that your selected combination will not exceed the power available for modules.
Chassis.bk : APPENDC Page 2 Monday, February 10, 1997 1:11 PM C-2 APPENDIX C: MSH POWER CONSUMPTION LIMITS Power consumption calculations must include the power used by the chassis and its components. ■ The basic chassis (3C18000), fitted with display panel, thermal management unit and backplane, consumes 67 watts (5.7 A @ +5V and 3.2A @ +12V). ■ A chassis fitted with an FDDI backplane (3C18001 or converted 3C18000) consumes an additional 19 watt (an additional 3.8A @ +5V).
Chassis.bk : APPENDC Page 3 Monday, February 10, 1997 1:11 PM Calculating Power Consumption C-3 If you have a 3C12010 ECS Coaxial module with a 3C18082 ECS-MSH converter installed in your MSH chassis, you must have at least one 375W PSU present, or two if you want resilience. The 3C18012 525W PSU does not provide the -9V supply required by the ECS Coaxial module. To calculate actual total current requirements, use the following equations.
