Keyword Description
Whenever communication with an EC card occurs, the associated ECLKEXP value
is automatically set to Y. Therefore, there is no need to explicitly establish a
connection to a particular expansion shelf. The assumption is that connection to an
EC card would not occur if there was no intention to actually use the expansion
shelf associated with it. Setting ECLKEXP to N while communication with that EC
card is continuing causes the ECLKEXP value to automatically return to Y.
When removing an expansion shelf from a TimeHub system, set the ECLKEXP
settings for EC cards in that shelf to N after the shelf connection was removed. This
prevents the EXCLKGONE condition from being reported for those EC cards.
Command Examples:
Retrieve the current setting of ECLKEXP for expansion shelf 2 (S2-) for the right
side Expansion Controller card (CLK2).
For each expansion shelf, the left side EC card (labeled EC1 on the shelf) is
identified by CLK1. The right side EC card (labeled EC2 on the shelf) is identified by
CLK2.
RTRV-EQPT::S2-CLK2:SV01:::PARAMETER=ECLKEXP;
The response is:
SYMMBITS 02-07-10 11:22:40
M SV01 COMPLD
"S2-CLK2::ECLKEXP=Y"
;
The preceding example shows that communication with the right side Controller
card in expansion shelf two is expected. If there is no communication, the following
condition is present:
"S2-CLK2:MJ,EXCLKGONE,NSA,07-10,13-05-52:\"Expansion CLK card
missing\""
Setting ECLKEXP to N causes this condition to end:
ED-EQPT::S2-CLK2:SV01:::ECLKEXP=N;
Note: If the Management card contains firmware version 4328D, the
Expansion Controller cards are identified by the AIDs ECC1 and
ECC2 instead of CLK1 and CLK2. The Clock cards on the main shelf
use the AIDs CLK1 and CLK2.
