Page 36: Post Overview
If a terminal or a monitor is not connected to serial port A (default port) of a workstation or server to be tested, the keyboard LEDs are used to determine error conditions. See Section 3.7, “System and Keyboard LEDs” on page 3-22 Sun Ultra 60 Service Manual • August 2001...
Page 37: Setting Up A Tip Connection
3.2.1 Setting Up a Tip Connection A tip connection enables a remote shell window to be used as a terminal to display test data of a system being tested. Serial port A or serial port B of a tested system unit is used to establish the tip connection between the system unit being tested and another Sun workstation monitor or TTY-type terminal.

Page 225 The PHY chip integrates a 100BASE-T physical coding sub-layer (PCS) and a complete 10BASE-T module in a single chip. It provides a standard MII to communicate between the physical signaling and the medium access control layers for both 100BASE-X and 10BASE-T operations. The PHY IC interfaces to the 100- Mbps physical-medium-dependent transceiver Twister IC.
Page 226 MII port timing encompasses two configurations involving the use of either an on- board transceiver or external transceivers. For either transceiver configuration, the MII port timing is the same because MII operates with a 40-nanosecond cycle time. C-26 Sun Ultra 60 Service Manual • August 2001...

illustrates MII being used to interconnect both integrated circuits and FIGURE C-8 circuit assemblies. This enables separate signal transmission paths to exist between the reconciliation sublayer, embedded in the Cheerio ASIC, and a local PHY IC, and between the reconciliation sublayer and a remote PHY IC. The unidirectional paths between the reconciliation sublayer and the local PHY IC are composed of sections A1, B1, C1 and D1.
