The HIRES VME crates, hmotcrate and hccdvmep, control all of the motorized stages and the CCD image taking functions of the spectrograph. This document describes how to access and boot the crates, and warning signs for error conditions.

Telnet'ing to the VME Crates

There are two ways to directly access a VME crate console session, described below. Note that the HIRES user menus contain entries to either TIP (terminal server connection) or Telnet (ethernet connection) to the crates, under Engineering -> TIP Motor Crate, for example.

Ethernet hostname (or IP address) connection

For the HIRES motor crate: telnet hmotcrate

For the HIRES CCD crate: telnet hccdvmep

Note: additional information is available at the HIRES Network Info page.

lehoula{hireseng}37: telnet hmotcrate
Trying 192.168.4.8 ...
Connected to hmotcrate.
Escape character is '^]'.

VxWorks login: 

The login name and password can be obtained from a Support Astronomer. At a future date all VME crates will utilize identical login parameters to minimize confusion. To log out of an ethernet session simply type "logout"

Terminal Server (TIP) connections

The HIRES VME console is connected to through a direct line from the K1 terminal server 'tserver1'. The channels for HIRES access are 3012 (hmotcrate) and 2009 (hccdvmep). To connect to the motor crate through this TIP line, type the following:

For the HIRES motor crate: telnet tserver1 3012

For the HIRES CCD crate: telnet k1consoles 2009

For example:

lehoula{hires}62: telnet tserver1 3012

Trying 128.171.95.140 ...
Connected to tserver1.
Escape character is '^]'.

One must hit "Enter" to activiate the session. To exit, type "Control-]". If the session is active, the arrow prompt appears:

->

If you do not get an arrow prompt, then there is an error in the terminal server connection. If another user owns the connection the following message results:

telnet: connect: Connection refused

If you cannot get into an active session, connect to the VME crate via ethernet.

Rebooting the VME crates

There are two fundamental ways to reboot a VME CPU.

From the TIP or ethernet connection

The crates can be booted directly from any login session (TIP or ethernet), by simply typing "reboot":

-> reboot

The behaviour of the two types of session under reboot is different, however. The TIP session is a "live" connection to the console, so you will see the auto-boot countdown and parameter table scroll by. Do not type anything in the window during the TIP session reboot. During the countdown the default boot parameters can inadvertantly be modified. In fact, it is best to get your cursor out of there during the boot-up.

If your connection is via ethernet, the session will hang, and log itself out, so you must reestablish the connection if you want it.

The startup scripts for either crate load automatically.

Hitting the Reset switch on the CPU

The HIRES VME crates are in a single rack in the instrument electronics enclosure on the RNAS deck of Keck-1. The SPARC CPU's can be rebooted by hitting the "Reset" switch that is somewhat hidden by adjoining connections on the board. It is a spring-loaded toggle switch. When the CPU has been successfully rebooted, the red LED's will blink in a recycled row.

Tasks and Error Conditions

The active processes for the two crates under normal operating condtions are:

The CCD crate has a monitor task running, "dewar_fill", that checks the LN2 levels of the 3.8 liter CCD dewar, and the 50 liter storage dewar. Messages are printed every 10 seconds of the form:

dewar_fill[0]: Monitoring for 6256 mins. Control enabled for last 6256 mins.
dewar_fill[0]: dewar is   98.6 percent full  tank level is   71.8 percent full
dewar_fill[0]: dewar temperature is -120.0 degrees C
dewar_fill[0]: 30 minutes since last fill

If you should log onto the crate and NOT see these messages posted every 10s, then automatic dewar fills will not be enabled, and the CCD crate should be rebooted immediately.
