34 PARAGON II USER GUIDE
• When a blocked switch is detected, it will be displayed in red color in Selection menu (in
order of channel number only) on OSUI to distinguish from a switch that has available path
reach (in purple).
• The ‘Blocked Channel/switch Identification’ is User Station dependent. User login on
different User Station may see different blocked channels.
Blocked Channels/Switch Identification
Definition of a blocked channel:
• Channel that is active and unoccupied by a user.
• User is unable to switch to that channel because there is no available path in upper tier.
Definition of a blocked switch:
• All tier paths from lower tier switches to that switch are occupied.
• User is unable to switch to servers that are connected to channel ports of the switch.
The identification of blocked channels is fully supported whether in a single base or multiple
bases regular Paragon configuration with some limitations as below.
• Blocked channel/switch identification only functions within a regular Paragon configuration
(no diamond connection and triangle connection inside). There is no guarantee that it will
function correctly in diamond or triangle configuration (For additional information about
these two configurations, see Non-Standard Tier Configuration in Chapter 7). However,
from user's perspective, the user behavior on light blue channel (the blocked one) is the same
as on green channel (the active and unoccupied one). Same does on the blocked switch.
• Blocked channel/switch identification are only activated in Private mode. This feature will
be disabled when in PC Share or P-View modes.
Manually Selecting the Access Path
When all tiered devices in the Paragon II system are implemented with firmware version later
than 3E3, you can manually choose a path to access a target server in the channel number view.
For older Paragon I or Paragon II products to support this feature, see the note in the end of this
section for more information.
1. Make sure you are in the channel number view in the Selection Menu. If not, press F12 to
toggle the view.
2. Press the Ç and È keys to highlight one of the channel ports in purple (available paths) or
yellow (in PC share mode) which are connected to a tier device (a tier device is indicated
with the symbol “--” displayed in the Scn field ).
