Switch 1005 Installation and Removal 2-7
Removing the Switch 1005
You do not need to power off the MSH chassis before removing the
Switch 1005. However, you should warn any users attached to the
Switch of the disruption in operation.
1 Undo the screws from the locking bar of the MSH chassis and lift the
bar away from the chassis.
2 Operate the module ejectors correctly, as shown in the MSH User Guide
referenced above. Store the removed Switch safely to avoid damage.
Note that the ejectors on the Expansion Module are dummy.
3 If you are not going to install a replacement module in the vacated slot
immediately, cover with a blanking plate.
4 Replace the locking bar and secure with the screws removed earlier.
Operation after Power-up
In an Unmanaged System
The links LK1 to LK5 are used to set the Switch’s backplane connections
in an unmanaged MSH chassis. These settings are used when the MSH
chassis containing the Switch is first powered-up. Subsequent changes
made to the settings directly through the Switch’s onboard
management software, either via an SNMP Network Manager or using
the VT100 interface, will be backed-up in non-volatile memory, and
will override the manual link settings if the Switch is subsequently
reset. If, however the Switch detects that the link settings have
changed since the last reset, the new link setting is applied and any
configuration stored in memory is deleted.
