housing until the card seats and the drawer is flush with the remainder of the back panel.
8 Hand tighten the screws clockwise on the faceplate to keep the Summit XEN Card in place.
NOTE
To ensure that your module is undamaged upon installation, you can correlate factory test data with
your installation site test data by consulting the average power reference values shown on the XENPAK
module test data sheet (Part No. 121074-00) enclosed with your module.
To remove an XENPAK module:
1 Turn the two captive screws counter-clockwise until they are completely free from the Summit XEN.
(The captive screws remain attached to the XENPAK module.)
WARNING!
Remove the SC fiber-optic connector from the XENPAK module before removing the module from
the Summit XEN card.
2 Remove the SC fiber-optic connector from the XENPAK module.
WARNING!
XENPAK modules become very hot after prolonged use. Take care when removing a XENPAK from
the chassis. If the module is too hot to touch, disengage the module and allow it to cool before
removing it completely.
3 Gripping both captive screws, pull the XENPAK module out of the card.
4 Place the dust covers back into the XENPAK module connectors.
5 Place the XENPAK module immediately into an antistatic container to protect it from ESD damage
and dust.
Installing the External Power System
The Extreme External Power System (EPS) allows you to add a redundant power supply to the
Summit 400 switch to protect against a power supply failure. It consists of a tray (EPS-T) that holds one
or two EPS-160 power supplies. Each EPS-160 provides one-to-one redundancy to an attached Extreme
switch. Please check the Extreme website or with your local sales representative for a list of compatible
Extreme switches.
The EPS can be ordered with one or two EPS-160 power supplies. You can order an additional EPS-160
to add to an EPS system. If you do not already have an EPS-T, you can order one from your sales
representative. The EPS-160 installs into an existing EPS-T rack-mountable chassis.Each individual
EPS-160 ships with an AC cord for use in the USA and a special redundant power supply cable.
