Insert the card into the card guides ensuring that the component side of the card
faces the right. Firmly push the card into the position ensuring that the card mates
correctly with the backplane connection.
After installing a module controller card you must reinstall the blanking plate.
MK511/2 Module Switch Cards
Up to 8 module switch cards can be connected to the module backplane to pro-
vide a first layer of switching. Even numbered backplane connectors carry plane
0 of the switch network, the odd numbered connectors carry plane 1. A fully con-
nected module containing single SPARC boards requires just two cards in slots
0 and 1, whereas a module containing quad-SPARC boards requires 8 switch
cards.
The MK511 contains a single Elite that provides the first level of network switch-
ing. The MK512 is a buffer card that has no switching and is used solely when
directly connecting two modules — in this case one module contains MK511
switch cards, the second contains MK512 buffer cards.
Neither card has special installation requirements, and neither card includes field
serviceable components.
MK515 Module Control Card
Monitors the status and configuration of the module, propagating error condi-
tions over the CAN bus (for interception by the System Software) and initiating
module shutdown under critical conditions (such as major component failure).
Field Upgradeable Components
The MK515 has the following field upgradeable components:
•
H8 ROM.
•
Non-volatile RAM (NVRAM).
