Table 39: Ioa Management Information - Juniper JUNOSE SOFTWARE FOR E SERIES 11.3.X - SYSTEM BASICS CONFIGURATION GUIDE 2010-10-04 Configuration Manual

JunosE 11.3.x System Basics Configuration Guide
344
A line module on the E120 and E320 routers can accommodate one full-height IOA or
up to two half-height IOAs per slot. In the software, adapter 0 identifies the right IOA bay
(E120 router) and the upper IOA bay (E320 router); adapter 1 identifies the left IOA bay
(E120 router) and the lower IOA bay (E320 router).
You can configure the slot by using the command-line interface (CLI), as well as the
individual IOAs. For example, if you want to disable the line module installed in slot 3,
issue the slot disable 3 command. If you want to disable the IOA in the upper bay or left
bay of slot 3, issue the adapter disable 3/0 command. Table 39 on page 344 lists the IOA
bay values that you use to manage half-height and full-height IOAs.
For some IOAs, issuing the adapter disable 3/0 command reboots the line module.
Modules that support hot-swapping enable you to remove and add an IOA in a slot
without rebooting the line module. If the slot is populated with another active IOA, it
continues to operate.
Depending on the IOA type, you can manage IOAs from certain slots or bays. Table 39
on page 344 lists the IOA management information, including valid IOA combinations and
hot-swapping support.
