Installing A Line Module Or An Ioa - Juniper E120 - RELEASE 11.1.X HARDWARE GUIDE 3-25-2010 Hardware Manual

CAUTION: We recommend that you power down the router before removing or
installing an IOA shelf between two slots that have modules installed in them already.
Otherwise, you might short-circuit the installed modules if you accidentally touch
the shelf to a module. An IOA shelf installation guide is available to ensure safe
installation. Contact your account representative for more information.

Installing a Line Module or an IOA

This section describes the procedures for installing line modules and IOAs.
NOTE: Install the IOA module before you install the corresponding line module;
otherwise, the diagnostics fail and the line module's status is listed as inactive when
you issue the show version command. If this occurs, remove and reinsert the line
module.
The router supports hot-swapping of line modules and IOAs. Hot-swapping enables
you to add or remove a line module without powering down the system. IOAs that
support hot-swapping enable you to add or remove an IOA without rebooting the
line module. See Table 4 on page 32 for a list of hot-swappable IOAs.
To install a line module or IOA:
1.
2.
NOTE: Line modules are in the front of the system and IOAs are in the back of the
system. See Table 4 on page 32 for IOA slot locations and combinations.

Ground yourself by using an antistatic wrist strap or other device and connect
it to one of the ESD grounding jacks.
Remove the blank IOA filler panel from the slot.
Align the shelf's guide pins with the corresponding holes in the midplane and
insert the threaded shaft into the hole in the midplane between the upper/right
bay and lower/left bay. Be sure the threaded shaft is visible from the right side.
(See Figure 20 on page 40.)
Using a flathead screwdriver, tighten the screw snugly to secure the shelf.
Ground yourself by using an antistatic wrist strap or other device and connect
it to one of the ESD grounding jacks.
Choose the slot where you want to insert the line module or IOA.
With a No. 2 Phillips screwdriver, loosen the screws that secure the blank filler
panel covering the empty chassis slot, if present, and remove the filler panel.
Remove the line module or IOA from its antistatic bag, being careful not to touch
module components, pins, leads, or solder connections.
