Installing A Power Module - NEC QX-S6648XP-6Q Installation Manual

Installation Guide
QX-S6600 Series Ethernet Switches

3.4.1 Installing a power module

CAUTION:
Follow the forward inertia of the power module when inserting it into the chassis, and make sure the power

module has firm contact with the connectors on the backplane.
To prevent damage to the connectors inside the switch chassis, insert the power module gently. If you

encounter a hard resistance while inserting the power module, pull out the power module and insert it
again.
If only one power module is installed, install a power filler module in the empty power module slot for good

ventilation of the switch.
Save the blank panel and the packaging box and packaging bag of the power module for future use.

The power module installation procedures are the same for the QX-S6600 Series Ethernet
Switches. This section uses the QX-S6632QP switch as an example.
To install a power module into the switch:
1) Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is
well grounded.
2) Unpack the power module and check that the power module model is correct.
3) Correctly orient the power module with the power module slot (see Figure 3-19), grasp
the handle of the power module with one hand and support its bottom with the other,
and slide the power module slowly along the guide rails into the slot. The slot is
foolproof. If you cannot insert the power module into the slot, re-orient the power
module rather than use excessive force to push it in.
