BlackDiamond 6800 Series I/O Modules
1 If you have a PoS module, the link is up, but the PPP/VLAN interface might not be up. To determine whether PPP is up, use
the
show ppp command to display PPP status information.
Installing I/O Modules
You can insert I/O modules at any time, without causing disruption of network services. Complete the
action of inserting a BlackDiamond I/O module in a reasonable time frame. Be sure to insert the
module completely to avoid partial insertion or connection of backplane connectors.
You need the following tools and equipment to install an I/O module:
ESD-preventive wrist strap
# 1 Phillips screwdriver
I/O module
Appropriate type of cable for the I/O module you plan to install
