Cabletron Systems manual Checking Network Status, Chassis Type, 2-14, Using the EMM-E6 Hub View

Using the EMM-E6 Hub View

NOTE

If your device firmware can accept four-digit year values, the Date field will allow you to enter the year portion in one-, two-, or four-digit format. If you choose to enter one or two digits for the year, any value greater than or equal to 88 will be presumed to be in the 1900s; a value of 87 or less is presumed to be in the 2000s. No matter which entry format you choose, the year will still be displayed and set as a four-digit value.

If your device firmware cannot accept four-digit year values, the Date field will allow you to enter the year portion in one- or two-digit format (with leading zeros supplied automatically for single-digit entries). No presumption is made about the century, and any two-digit year value (from 00 to 99) will be accepted.

Attempts to set the date may result in one of three different error messages. Two of these messages will indicate that the wrong number of digits has been used for the year value, and will indicate the appropriate number of digits to use for the selected device; the third message will indicate that the entered date is invalid because it is not an actual calendar date (such as 02/29 in a non-leap year, any month value greater than 12, or any day value greater than 31).

Chassis Type

Indicates the type of hub that houses this EMM-E6 — MMAC-M3FNB, MMAC-M5FNB, and so forth — and whether or not the hub contains a shunting backplane.

To change the name, location, contact, date, or time:

1.Highlight the appropriate field and type the new values.

2.Press Enter or Return on the keyboard to save each change before moving on to another; each change will appear on the front panel as soon as Enter or Return is pressed.

The Device Status window also allows you to enable or disable the audible chassis alarm for your chassis. When the chassis alarm is enabled, an alarm will sound when high temperature or low voltage conditions occur in the chassis. To enable or disable the chassis alarm:

1.In the Audible Alarm State field, click on theEnabled or Disabled option, as desired. The chassis alarm will be enabled or disabled, as selected.

Checking Network Status

The Network Status window provides information about each active repeating network, or channel, on the EMM-E6.

To access the Network Status window:

1.Click mouse button 1 in the appropriate Network Connection box (one displaying the letter that identifies the network you are interested in: A, B, or C).
