Summit 400-48 Switch Overview and Installation
Installing the Summit XEN Card
The Summit 400-48t allows you to add up to two 10 Gigabit uplink modules to increase the bandwidth
of the switch. The Summit XEN Card supports either of these Extreme XENPAK optical transceivers:
• SR XENPAK for the 850 nm range
• LR XENPAK for the 1310 nm range
• ER XENPAK for the 1550 nm range
CAUTION
The Summit XEN Card cannot be hot-swapped. Before installing the Summit XEN Card into the Summit
400-48t, you must turn off the switch. Use only XENPAK modules approved by Extreme Networks.
To install the Summit XEN Card:
1 Disconnect the AC power from the Summit 400.
2 Use a standard screwdriver to remove the blank plate to expose the opening for the card.
3 Install the XENPAK optical transceiver modules onto the card. For more detail on this step, see
“Installing XENPAK Optical Transceiver Modules”.
4 Place the Summit XEN Card into the drawer.
5 Carefully close the drawer to engage the card.
Installing XENPAK Optical Transceiver Modules
This section describes installing and removing the XENPAK module, a 10 Gbps optical transceiver. Both
the LR XENPAK and the ER XENPAK appear and install the same. An example of an XENPAK module
is shown in Figure 9.

The XENPAK module is a Class 1 Laser device that operates at 5 V. Use only Extreme-approved devices
on all Extreme switches.
