Show Memory Output
On some systems, the show memory [detail] command may show the cumulative memory
allocation field as negative (9010).
TFTP Download of Configuration Files
When using TFTP to download a configuration file and selecting “no” for the switch reboot request,
rebooting the switch at a later time will display a message that the configuration file has been
corrupted. The user will be prompted to reboot the switch with factory default parameters. If an
immediate reboot is performed after the download configuration command, the configuration file will
be initiated correctly (12413).
System Related – BlackDiamond Switch
Using 110v Power on a BlackDiamond Switch
The BlackDiamond switch requires 220-volt power for correct operation. If 110-volt power is supplied,
not all the I/O modules of the BlackDiamond switch may power up. The MSM will perform power
calculations and will power up the maximum number of I/O modules from left (slot1) to right (slot 8).
A module can be skipped if that module is not within the power budget, but the subsequent module is.
Using 110 volts, only four modules will typically be powered on (4877).
Enabled IdleTimeouts and Multiple BlackDiamond Console Connections
The idletimeouts feature should not be enabled if serial ports from both MSMs in a two MSM
configuration are used for console connections. If the idletimeouts feature is enabled in this scenario,
console sessions will not be re-established correctly (5093).
Modem Port on MSMs
The lower 9-pin serial port labeled as “modem” on the MSM blade for the BlackDiamond switch does
not allow any connectivity to the device at this time. The upper 9-pin console ports of both the primary
and secondary MSM can be used as console or modem connection (5179).
Hot Removal of an I/O Module with Traffic
If a BlackDiamond I/O module is removed during traffic flow to the module, several error messages
may be written to the log immediately following. These messages should cease to occur after about 10
seconds. Under this circumstance, the error messages can be safely ignored. The error messages may
contain one or more of the following (5160, 5082):
04/13/1999 17:18.46 <DBUG:KERN> killPacket: HW pqmWaitRx failed
04/13/1999 17:18.46 <DBUG:KERN> pqmWaitKill failed. Card 1 is removed.
Removal/Insertion of an I/O Module
The action of inserting or removing a BlackDiamond I/O module should be completed in a reasonable
time frame. Be sure to remove or insert the module completely and to avoid partial insertion or
connection of backplane connectors (7455).
