Caution: If you install an ERX-7xx model or ERX-310 router directly above an ERX-14xx model in the same rack, you must install a plenum between the ERX-7xx model or ERX-310 router and the ERX-14xx model so that the air can circulate between the systems. (See Figure 53.) This plenum is available from Juniper Networks. |
If you install an ERX-14xx model above an ERX-7xx model or ERX-310 router, there is no need to install a plenum between the units because the ERX-7xx models and ERX-310 routers vent air out the side of the chassis.
